Read PACT Contract Testing: A Step-by-Step Guide Implement Contract Testing for Free WhatsApp LinkedIn X (Twitter) Copy link In our previous contract testing article, we covered the basics of what contract testing is and how it works. Now, in this blog post, we'll introduce you to a popular tool for contract testing—PACT Contract testing. What is PACT contract testing? Let's understand why PACT contract testing became essential through a real team retrospective about a production failure. Q: Why did our user profile feature break in production when the Auth service team said they only made a "minor update"? A: We were consuming their /user endpoint expecting the response to always include a phone field, but they changed it to optional without telling us. Q: But didn't we have unit tests covering the user profile logic? A: Yes, but our unit tests were mocking the Auth service response with the old structure. Our mocks had the phone field as required, so our tests passed even though the real service changed. Q: Why didn't integration tests catch this? A: We only run full integration tests in staging once a week because they're slow and flaky. By then, the Auth team had already deployed to production and moved on to other features. Q: How could we have prevented this? A: If we had a contract between our services - something that both teams agreed upon and tested against - this wouldn't have happened. That's exactly what PACT contract testing solves. Contract tests combine the lightness of unit tests with the confidence of integration tests and should be part of your development toolkit. PACT is a code-based tool used for testing interactions between service consumers and providers in a microservices architecture. Essentially, it helps developers ensure that services (like APIs or microservices) can communicate with each other correctly by validating each side against a set of agreed-upon rules or "contracts". Here's what PACT does in a nutshell: It allows developers to define the expectations of an interaction between services in a format that can be shared and understood by both sides. PACT provides a framework to write these contracts and tests for both the consuming service (the one making the requests) and the providing service (the one responding to the requests). PACT has a lot of manual effort involved in generating the test cases, move beyond that and adopt in a fast-performing approach that auto generates test cases based on your application's network traffic. Curious to know more? When the consumer and provider tests are run, PACT checks whether both sides adhere to the contract. If either side does not meet the contract, the tests fail, indicating an issue in the integration. By automating these checks, PACT helps teams catch potential integration issues early and often, which is particularly useful in CI/CD environments. So, PACT focuses on preventing breaking changes in the interactions between services, which is critical for maintaining a reliable and robust system when multiple teams are working on different services in parallel. Importance of PACT Contract Testing ➡️PACT reduces the complexity of the environment that is needed to verify integrations , as well as isolates changes to the specific interaction between services. This prevents cascading failures and simplifies debugging. Managing different environments for different purposes is definitely a tedious task to do, companies like Zoop, Skaud, PayU, Nykaa etc, uses a smart approach that takes away all the need to manage dedicated environments, allowing you to focus on more important things. ➡️Decoupling for Independence: PACT enables microservices to thrive on decoupled, independent development, testing, and deployment, ensuring adherence to contracts and reducing compatibility risks during the migration from monoliths to microservices. ➡️Swift Issue Detection: PACT's early identification of compatibility problems during development means faster feedback, with precise, interaction-focused tests that expedite feedback and streamline change signoffs. ➡️Enhanced Collaboration and Confidence: Clear, shared service interaction contracts reduce misunderstandings, fostering collaboration and developer confidence in releasing changes without breaking existing contracts. ➡️Living Documentation: Pact contracts serve as dynamic, clear-cut documentation, simplifying developers' comprehension of integration points. ➡️Reduced Service Outages: Pact contract tests swiftly highlight provider service changes that break consumer expectations, facilitating quick identification and resolution of disruptive modifications. How does Pact implement contract testing? Pact implements contract testing through a process that involves both the consumer and the provider of a service , following these steps: ➡️Consumer Testing: The consumer of a service (e.g., a client application) writes a test for the expected interaction with the provider's service. While writing this test, Pact stubs out the actual provider service and records the expectations of the consumer—what kind of request it will make and what kind of response it expects—into a Pact file, which is a JSON file acting as the contract. The consumer test is run with the Pact mock service, which ensures the consumer can handle the expected response from the provider. ➡️Pact File Generation: When the consumer tests pass, the Pact file (contract) is generated. This file includes the defined requests and the expected responses. ➡️Provider Verification: The provider then takes this Pact file and runs it against their service to verify that the service can meet the contract's expectations. The provider's tests take each request recorded in the Pact file and compare it against the actual response the service gives. If they match, the provider is considered to be in compliance with the contract. ➡️Publishing Results: Results of the provider verification can be published to a Pact Broker, which is a repository for Pact files. This allows for versioning of contracts and tracking of the verifications. Both the consumer and the provider use the Pact Broker to publish and retrieve Pact files. It helps to ensure that both parties in the service interaction are always testing against the latest contract. ➡️Continuous Integration: Pact is often integrated into the CI/CD pipeline . Whenever changes are made to the consumer or provider, the corresponding contract tests are automatically run. This helps in identifying any breaches in the contract immediately when a change is made, ensuring that any integration issues are caught and addressed early in the development lifecycle. ➡️Version Control: Pact supports semantic versioning of contracts, which helps in managing the compatibility of interactions between different versions of the consumer and provider services. By automating the creation and verification of these contracts, Pact helps maintain a reliable system of independent services by ensuring they can communicate as expected, reducing the likelihood of integration issues in a microservices architecture. How to perform Pact Contract Testing? Now we all know that Pact is a code-first tool for testing HTTP and message integrations using contract tests. Instead of testing the internal details of each service, PACT contract testing focus on the "contract" or the agreement between services on how their APIs should behave. For this example, we have created a hypothetical scenario where a client app expects to fetch user data from a service. Step 1: Define the Consumer Test In the consumer service, you would write a test that defines the expected interaction with the provider's API. Step 2: Run the Consumer Test When this test is executed, the pact context manager starts the mock service, and the defined interaction is registered with it. Then, the test makes a request to the mock service, which checks that the request matches the registered interaction. If it does, it responds with the predefined response. Step 3: Generate the Contract (Pact File) If all assertions pass and the test completes successfully, Pact will generate a .json file representing the contract. This file is then used by the provider to verify that their API meets the expectations defined by the consumer. { "consumer": { "name": "ConsumerService" }, "provider": { "name": "ProviderService" }, "interactions": [ { "description": "a request for user id 1", "providerState": "a user with id 1 exists", "request": { "method": "GET", "path": "/user/1" }, "response": { "status": 200, "body": { "id": 1, "name": "John Doe", "email": "john.doe@example.com" } } } ], "metadata": { "pactSpecification": { "version": "2.0.0" } } } Step 4: Verify the Provider with the Pact File The provider's test suite would use this .json Pact file to ensure their service can handle the requests and send the expected responses. The provider doesn't necessarily need to know the internals of the consumer; it just needs to satisfy the contract as outlined in the Pact file. The Verifier uses the pact file to make requests to the actual provider service and checks that the responses match the contract. If they do, the provider has met the contract, and you can be confident that the provider and consumer can communicate correctly. Problems with PACT If your primary goal is keeping contract testing simple and with lesser overheads, PACT may not be the ideal tool. PACT contract testing has become very popular among teams off late given its simplicity and effectiveness. But it comes with its own set of challenges, making adoption at scale a challenge. It’s not always straightforward, it demands a considerable amount of manual effort and time. There are some obvious challenges in getting started and also the manual intervention in contract maintenance doesn’t make it the perfect fit for testing microservices alone. 👉Complex setup and high maintenance 👉CI/CD Pipeline Integration Challenges 👉High Learning Curve 👉Consumer Complexity 👉Test Data Management Let’s get started with all of them, one-by-one. 1. Lots of Manual Effort Still Needed Pact contracts need to be maintained and updated as services evolve. Ensuring that contracts accurately reflect real interactions can become challenging, especially in rapidly changing environments. Ensuring that contracts accurately reflect the expected interactions can become complex, especially when multiple consumers are involved. Any time teams (especially producers) miss updating contracts, consumers start testing against incorrect behaviors which is when critical bugs start leaking into production. ➡Initial Contract Creation Writing the first version of a contract involves a detailed understanding of both the consumer's expectations and the provider's capabilities. Developers must manually define the interactions in test code. # Defining a contract in a consumer test @pact.given('user exists') @pact.upon_receiving('a request for a user') @pact.with_request(method='GET', path='/user/1') @pact.will_respond_with(status=200, body={'id': 1, 'name': 'John Doe'}) def test_get_user(): # Test logic here This change must be communicated and agreed upon by all consumers of the API, adding coordination overhead. ➡ Maintaining Contract Tests The test suite for both the consumer and the provider will grow as new features are added. This increased test suite size can make maintenance more difficult. Each function represents a new contract or a part of a contract that must be maintained. # Over time, you may end up with multiple contract tests def test_get_user(): # ... def test_update_user(): # ... def test_delete_user(): # ... 2. Testing Asynchronous Patterns Pact supports non-HTTP communications, like message queues or event-driven systems, but this support varies by language and can be less mature than HTTP testing. // A JavaScript example for message provider verification let messagePact = new MessageProviderPact({ messageProviders: { 'a user created message': () => Promise.resolve({ /*...message contents...*/ }), }, // ... }); This requires additional understanding of how Pact handles asynchronous message contracts, which might not be as straightforward as HTTP. 3. Consumer Complexity In cases where multiple consumers interact with a single provider, managing and coordinating contracts for all consumers can become intricate. ➡ Dependency Chains Consumer A might depend on Consumer B, which in turn depends on the Provider. Changes made by Provider could potentially impact both Consumer A and the Consumer B. This chain of dependencies complicates the contract management process. 💡 Let’s understand this with an example: Given Services: - Provider : User Management API. - Consumer B : Profile Management Service, depends on the Provider. - Consumer A: Front-end Application, depends on Consumer B. Dependency Chain: - ` Consumer A ` depends on ` Consumer B `, which in turn depends on the `Provider`. Change Scenario: - The ` Provider ` adds a new mandatory field ` birthdate ` to its user data response. - ` Consumer B ` updates its contract to incorporate ` birthdate ` and exposes it through its endpoint. - ` Consumer A ` now has a failing contract because it doesn't expect `birthdate` in the data it receives from ` Consumer B `. Impact: - ` Consumer A ` needs to update its contract and UI to handle the new field. - ` Provider ` needs to coordinate changes with both the ` Consumer B ` and ` Consumer A ` to maintain contract compatibility. - The ` Provider ` must be aware of how its changes affect downstream services to avoid breaking their contracts. ➡ Coordination Between Teams When multiple teams are involved, coordination becomes crucial. Any change to a contract by one team must be communicated to and accepted by all other teams that are consumers of that API. # Communication overhead example # Team A sends a message to Team B: "We've updated the contract for the /user endpoint, please review the changes." This communication often happens outside of Pact, such as via team meetings, emails, or chat systems. Ensuring that all consumer teams are aware of contract changes and aligned on the updates can require effective communication channels and documentation. 4. Test Data Management Test data management in Pact involves ensuring that the data used during contract testing accurately represents real-world scenarios while maintaining consistency, integrity, and privacy. This can be a significant challenge, particularly in complex microservices ecosystems. The problems that might arise would be: ➡ Data Generation Creating meaningful and representative test data for all possible scenarios can be challenging. Services might need specific data states to test different interactions thoroughly. ➡ Data Synchronization PACT tests should use data that accurately reflects the behavior of the system. This means that the test data needs to be synchronized and consistent across different services to ensure realistic interactions. Mismatched or inconsistent data can lead to false positives or negatives during testing. Example: If the consumer's Pact test expects a user with ID 1, but the provider's test environment doesn't have this user, the verification will fail. ➡ Partial Mocking Limitations Because Pact uses a mock service to simulate provider responses, it's possible to get false positives if the provider's actual behavior differs from the mocked behavior. This can happen if the provider's implementation changes without corresponding changes to the contract. How we've fixed the biggest problem with the Pact workflow? PACT driven integration testing has becoming very popular among teams off late given its simplicity and effectiveness. But some obvious challenges in getting started and contract maintenance still does not make it the perfect solution for integration testing. So, we at HyperTest have built an innovative approach that overcomes these shortcomings, making contract testing easy to implement and scalable. In this approach, HyperTest builds contract tests for multiple services autonomously by monitoring actual flows from production traffic. Principally there are two modes i.e. record mode which records real world scenarios 24x7 and replay/test mode that then replays these scenarios to test the service with an external system, without actually making it live and running. Let's explore how these two modes work: Record mode: Automatic tests generation based on real-world scenarios The HyperTest SDK is placed directly above a service or SUT. It observes and documents all incoming requests for traffic that the service receives. This includes recording the entire sequence of steps that the SUT takes in order to generate a response. The incoming requests represent the paths users take, and HyperTest captures them exactly as they occur. This ensures that no scenarios are overlooked, resulting in a comprehensive coverage of all possible test cases. In this mode HyperTest records: 👉The incoming request to the SUT 👉The outgoing requests from the SUT to downstream services and databases. Also, the response of these external systems 👉The response of the SUT which is stored (say X’) Replay/Test mode: Replay of recorded test scenarios with mocked dependencies During the (replay) Test mode, integrations between components are verified by replaying the exact transaction (request) recorded during the record mode. The service then makes external requests to downstream systems, databases, or queues whose response are already mocked. HyperTest uses the mocked response to complete these calls, then compares the response of the SUT in the record mode to the test mode. If the response changes, HyperTest reports a regression. Advantages of HyperTest over PACT This simple approach of HyperTest takes care of all the problems with PACT. Here is how: 👉Auto-generate service contracts with no maintenance required HyperTest observes actual calls (requests and responses) and builds contracts in minutes. If requests (consumer) or responses (producer) change breaking the contracts, respective service owners can approve changed contracts with a click for all producers or consumers rather than rewriting in PACT files. This updation of contracts (if needed) happens with every commit. Respective consumer - provider teams are notified on slack needing no separate communication. This instant feedback on changing behavior of external systems helps developers make rapid changes to their code before it breaks in production. 👉Test Data Management It is solved by design. HyperTest records real transactions with the real data. For example: ✅When testing for login, it has several real flows captured with user trying to login. ✅When it tests login, it will replay the same flow (with transactional data) and check if the same user is able to login to verify the right behavior of the application. HyperTest's approach to aligning test data with real transactions and dynamically updating mocks for external systems plays a vital role in achieving zero bugs in production. 👉Dependency Management HyperTest autonomously identifies relationships between different services and catches integration issues before they hit production. Through a comprehensive dependency graph, teams can effortlessly collaborate on one-to-one or one-to-many consumer-provider relationships. Notification on Disruption: Let's developer of a service know in advance when the contract between his and other services has changed. Quick Remediation: This notification enables quick awareness and immediate corrective action. Collaboration on Slack: This failure is pushed to a shared channel where all developers can collaborate 👉CI/CD integration for early issue detection and rollback prevention HyperTest identifies issues early in SDLC for developers to quickly test changes or new features and ensure they integrate seamlessly with rest of the system. ✅ Early Issue Detection ✅ Immediate Feedback Automatically run tests using your CI/CD pipeline when a new merge request is ready. The results can be observed on platforms like GitHub, GitLab or Bitbucket and sign-off knowing your change will not break your build in production. 👉Build Confidence Knowing that their changes have undergone rigorous testing and integration checks, devs can sign off with confidence, assured that their code will not break the production build. This confidence significantly reduces the likelihood of introducing bugs that could disrupt the live system.

Stop system headaches! Master SIT (System Integration Testing) & identify communication issues early. Best practices for a seamless system! 11 July 2024 06 Min. Read All you need to know about System Integration Testing (SIT) WhatsApp LinkedIn X (Twitter) Copy link Download the Checklist System Integration Testing (SIT) is the phase in the software development lifecycle that focuses on verifying the interactions between integrated components or systems. SIT evaluates the entire system’s functionality by testing how different modules work together. This type of testing ensures that various sub-systems communicate correctly, data transfers smoothly between components and the integrated system meets specified requirements. SIT helps detect issues related to interface mismatches, data format inconsistencies and integration errors early in the development process. By identifying and addressing these problems before the system goes live, SIT helps prevent costly fixes, improves software reliability and enhances overall system performance. Effective SIT contributes to a smoother deployment, higher user satisfaction and a well-functioning software product. How to Perform System Integration Testing? SIT verifies if different software components function together as a cohesive unit, meeting the overall system requirements. This is how SIT is performed: Process Description Planning and Test Design Define the SIT scope, identify components to be tested and design test cases covering various functionalities and integrations. Test Environment Setup Create a test environment that replicates the production setup as closely as possible. This includes installing necessary software, configuring systems and preparing test data. Test Execution and Defect Reporting Execute the designed test cases, meticulously documenting any errors or unexpected behaviour encountered. Report these defects to the development team for rectification immediately. Defect Resolution and Re-testing The development team fixes the reported defects and the SIT team re-executes the affected test cases to ensure the fixes work as intended. Regression Testing After fixing important defects, conduct regression testing to ensure new fixes haven not introduced regressions in other functionalities. See in action how HyperTest catches all the errors before they turn into bugs, right in the staging environment itself. Evaluation and Reporting Upon successful test completion, evaluate the overall system's functionality, performance and compliance with requirements. Document the testing process, results and recommendations in a comprehensive SIT report. Best Practices for System Integration Testing Here are best practices to optimise your SIT process: Clear Scope and Defined Entry/Exit Criteria: Set clear boundaries for what SIT will cover and establish well-defined criteria for starting and ending the testing phase. This ensures everyone is on the same page. Collaborative Effort: Involve stakeholders from development, business and testing teams. Use Subject Matter Experts (SMEs) to provide valuable insights into system functionalities and user workflows. Test Environment Fidelity: Replicate the production environment as closely as possible. This includes installing the same software versions, configuring identical network settings and preparing realistic test data. Prioritise Test Cases: Focus on important business functionalities and integrations first. Utilise risk-based testing to prioritise areas where failures could have the most significant impact. Defect Management and Communication: Establish a clear process for logging, reporting and tracking defects. Maintain open communication with development teams to ensure timely resolution and effective retesting. 💡 Example: An e-commerce application — during SIT, a test case might involve simulating a user adding an item to the cart, proceeding to checkout and using a payment gateway to complete the purchase. This scenario would test the integration between the shopping cart, product database, user authentication and payment processing systems.. Common Challenges and Solutions The following are some of the challenges of System Integration Testing along with their solutions. Complex Integration Points : Integrating multiple sub-systems is difficult due to differing interfaces, communication protocols and data formats. Solution : Detailed interface documentation and strong middleware solutions can simplify integration.

Visit HyperTest today! Related to Integration Testing Frequently Asked Questions 1. Why is System Integration Testing (SIT) important? System Integration Testing (SIT) is crucial because it ensures different parts of your system (applications, databases) work together seamlessly. Imagine building a house – individual bricks (code modules) may be perfect, but if they don't fit together, the house won't stand. SIT acts like the architect, identifying any compatibility or communication issues before you reach the final stages of development. 2. What is the purpose of System Integration Testing (SIT)? The purpose of SIT is to verify that integrated systems exchange data accurately and function as a cohesive whole. It focuses on how well different components interact and exposes any hidden integration problems that might not be apparent in individual unit tests. 3. What is the difference between System Integration Testing (SIT) and UAT (User Acceptance Testing)? The key difference between SIT and UAT (User Acceptance Testing) lies in the perspective. SIT looks at the system from a technical standpoint, ensuring components work together. UAT, on the other hand, focuses on whether the system meets user needs and expectations. Think of SIT as the internal quality check, while UAT is the final user exam that ensures the system is fit for purpose. For your next read Dive deeper with these related posts! 13 Min.

Discover the essentials of REST API, the web service communication protocol that simplifies interactions over the internet with its flexible, scalable, and developer-friendly architecture. 13 December 2023 14 Min. Read What is REST API? - REST API Explained WhatsApp LinkedIn X (Twitter) Copy link Access the Guide Is a significant part of your daily work routine spent sending API requests and examining the responses, or maybe the other way around? Well, guess what? REST API is like your trusty work buddy. But what exactly is a REST API, and how does it make your data-fetching tasks better? This article is here to break down the concept of APIs, provide REST APIs examples, and give you all the details you need to use them effectively. What is an API? First things first, let's begin from the basics to ensure a solid foundation. What exactly is an API? If you're already well-acquainted with this, feel free to skip this section and jump to the part that addresses your current needs the most. Simply put, APIs are the backbone of today’s software. Let’s take the library analogy to understand the meaning of APIs: Imagine an API as a librarian. You go to a librarian and ask for a book on a specific topic. The librarian understands your request and fetches the book from the shelves. Here, you don’t need to know where the book is or how the library is organized. The API (librarian) abstracts the complexity and presents you with a simple interface - asking for information and receiving it. Imagine you're using an app like "Agoda" to find a hotel room. Behind the scenes, a bunch of API requests are at play, darting around to compile the list of available rooms. It's not just about clicking buttons; APIs do the behind-the-scenes work. They process your request, gather responses, and that's how the whole frontend and backend system collaborates. So an API could be anything in any form. The only thing that it has to be is that it has to be a way to communicate with a software component. Types of APIs Each type of API serves a unique purpose and caters to different needs, just as different vehicles are designed for specific journeys. Open APIs (Public Transport) : Open APIs are like public buses or trains. They are available to everyone, providing services that are accessible to any developer or user with minimal restrictions. Just as public transport follows a fixed route and schedule, open APIs have well-defined standards and protocols, making them predictable and easy to use for integrating various applications and services. Internal APIs (Company Shuttle Service) : These APIs are like the shuttle services provided within a large corporate campus. They are not open to the public but are used internally to connect different departments or systems within an organization. Like a shuttle that efficiently moves employees between buildings, internal APIs enable smooth communication and data exchange between various internal software and applications. Partner APIs (Car Pooling Services) : Partner APIs are akin to carpooling services where access is granted to a select group of people outside the organization, usually business partners. They require specific rights or licenses, much like how a carpool requires a shared destination or agreement among its members. These APIs ensure secure and controlled data sharing, fostering collaboration between businesses. Composite APIs (Cargo Trains) : Just as a cargo train carries multiple containers and combines different goods for efficient transportation, composite APIs bundle several service calls into a single call. This reduces the client-server interaction and improves the performance of listeners in web interfaces. They are particularly useful in microservices architectures, where multiple services need to interact to perform a single task. REST APIs (Electric Cars) : REST (Representational State Transfer) APIs are the electric cars of the API world. They are modern, efficient, and use HTTP requests to GET, PUT, POST, and DELETE data. Known for their simplicity and statelessness, they are easy to integrate and are widely used in web services and applications. SOAP APIs (Trains) : SOAP (Simple Object Access Protocol) APIs are like trains. They are an older form of API, highly standardized, and follow a strict protocol. SOAP APIs are known for their security, transactional reliability, and predefined standards, making them suitable for enterprise-level and financial applications where security and robustness are paramount. GraphQL APIs (Personalized Taxi Service) : GraphQL APIs are like having a personalized taxi service. They allow clients to request exactly what they need, nothing more and nothing less. This flexibility and efficiency in fetching data make GraphQL APIs a favorite for complex systems with numerous and varied data types. What is a REST API? Coming back to the topic of this piece, let’s dive deep and discuss all about REST APIs. A REST API or REST web service is an API that follows that follows the rules of REST specification. A web service is defined by these rules: How software components will talk? What kind of messages they’ll send to each other? How requests and responses will be handled? A REST API, standing for Representational State Transfer API, is a set of architectural principles for designing networked applications. It leverages standard HTTP protocols and is used to build web services that are lightweight, maintainable, and scalable. You make a call from a client to a server, and you get the data back over the HTTP protocol. Architectural Style REST is an architectural style, not a standard or protocol. It was introduced by Roy Fielding in his 2001 doctoral dissertation. A RESTful API adheres to a set of constraints which, when followed, lead to a system that is performant, scalable, simple, modifiable, visible, portable, and reliable. REST itself is an underlying architecture of the web. Principles of REST REST APIs are built around resources, which are any kind of objects, data, or services that can be accessed by the client. Each resource has a unique URI (Uniform Resource Identifier). An API qualifies as a REST API if it follows these principles: Client-Server Architecture : The client application and the server application must be able to operate independently of each other. This separation allows for components to evolve independently, enhancing scalability and flexibility. Statelessness : Each request from the client to the server must contain all the information needed to understand and process the request. The server should not store any session state, making the API more scalable and robust. Cacheability : Responses should be defined as cacheable or non-cacheable. If a response is cacheable, the client cache is given the right to reuse that response data for later, equivalent requests. Layered System : A client cannot ordinarily tell whether it is connected directly to the server or to an intermediary along the way. Intermediary servers can improve system scalability by enabling load balancing and shared caches. Uniform Interface : This principle simplifies the architecture, as all interactions are done in a standardized way. It includes resource identification in requests, resource manipulation through representations, self-descriptive messages, and hypermedia as the engine of application state (HATEOAS). REST API Example It is always better to understand things with the help of examples, so let’s do the same with this and dive deeper into this REST API example. 👉Imagine a service that manages a digital library. This service provides a REST API to interact with its database of books. A client application wants to retrieve information about a specific book with the ID 123. Anatomy of the Request 1. Endpoint URL The endpoint is the URL where your API can be accessed by a client application. It represents the address of the resource on the server which the client wants to interact with. Example : https://api.digitalibrary.com/books/123 Components : Base URL : https://api.digitalibrary.com/ - The root address of the API. Path : /books/123 - Specifies the path to the resource. In this case, books is the collection, and 123 is the identifier for a specific book. 2. HTTP Method This determines the action to be performed on the resource. It aligns with the CRUD (Create, Read, Update, Delete) operations. Example : GET Purpose : In this case, GET is used to retrieve the book details from the server. 3. Headers Headers provide metadata about the request. They can include information about the format of the data, authentication credentials, etc. Example : Content-Type: application/json - Indicates that the request body format is JSON. Authorization: Bearer your-access-token - Authentication information, if required. 4. Request Body This is the data sent by the client to the API server. It's essential for methods like POST and PUT. Example : Not applicable for GET requests, as there is no need to send additional data. Purpose : For other methods, it might include details of the resource to be created or updated. 5. Query Parameters These are optional key-value pairs that appear at the end of the URL. They are used to filter, sort, or control the behavior of the API request. Example : https://api.digitalibrary.com/books/123?format=pdf&version=latest Purpose : In this example, the query parameters request the book in PDF format and specify that the latest version is needed. 6. Response Components : Status Code : Indicates the result of the request. E.g., 200 OK for success, 404 Not Found for an invalid ID, etc. Response Body : The data returned by the server. For a GET request, this would be the details of the book in JSON or XML format. Response Headers : Contains metadata sent by the server, like content type or server information. Client-Server Interaction in the REST API World Let's put everything together in a detailed request example: 1.Endpoint URL : https://api.digitalibrary.com/books/123 2. HTTP Method : GET 3. Headers : Accept: application/json (tells the server that the client expects JSON) Authorization: Bearer your-access-token (if authentication is required) 4. Request Body : None (as it's a GET request) 5. Query Parameters : None (assuming we're retrieving the book without filters) The client sends this request to the server. The server processes the request, interacts with the database to retrieve the book's details, and sends back a response. The response might look like this: Status Code : 200 OK 6. Response Body : { "id": 123, "title": "Learning REST APIs", "author": "Jane Doe", "year": 2021 } Response Headers : Content-Type: application/json; charset=utf-8 The HTTP Methods and REST World In the realm of RESTful web services, HTTP methods are akin to the verbs of a language, defining the action to be performed on a resource. Understanding these methods is crucial for leveraging the full potential of REST APIs. Let's delve into each of these methods, their purpose, and how they are used in the context of REST. 1. GET: Retrieve data from a server at the specified resource Safe and idempotent: Does not alter the state of the resource. Used for reading data. Example: fetch('') .then(response => response.json()) .then(data => console.log(data)); 2. POST: Send data to the server to create a new resource Non-idempotent: Multiple identical requests may create multiple resources. Commonly used for submitting form data. Example: fetch('', { method: 'POST', headers: { 'Content-Type': 'application/json', }, body: JSON.stringify({ name: 'New Item', price: 20 }) }) .then(response => response.json()) .then(data => console.log(data)); 3. PUT: Update a specific resource (or create it if it does not exist) Idempotent: Repeated requests produce the same result. Replaces the entire resource. Example: fetch('', { method: 'PUT', headers: { 'Content-Type': 'application/json', }, body: JSON.stringify({ name: 'Updated Item', price: 30 }) }) .then(response => response.json()) .then(data => console.log(data)); 4. DELETE: Remove the specified resource Idempotent : The resource is removed only once, no matter how many times the request is repeated. Used for deleting resources. Example: fetch('', { method: 'DELETE' }) .then(() => console.log('Item deleted')); 5. PATCH: Partially update a resource Non-idempotent: Repeated requests may have different effects. Only changes specified parts of the resource. Example: fetch('', { method: 'PATCH', headers: { 'Content-Type': 'application/json', }, body: JSON.stringify({ price: 25 }) }) .then(response => response.json()) .then(data => console.log(data)); RESTful Design Considerations When designing a RESTful service, it's important to adhere to the intended use of each HTTP method: Use GET for retrieving data. Use POST for creating new resources and actions that do not fit into the other methods. Use PUT and PATCH for updates, with PUT for full updates and PATCH for partial updates. Use DELETE for removing resources. Proper use of these methods ensures clarity and consistency in your API, making it more intuitive and easier to use for developers. This approach adheres to the REST architectural style, promoting stateless communication and standardized interactions between clients and servers. How REST is different from SOAP? REST (Representational State Transfer) and SOAP (Simple Object Access Protocol) are two different approaches to web service communication, each with its unique characteristics and use cases. Understanding their differences is key to choosing the right protocol for a specific application. Let's explore how REST and SOAP differ in various aspects: 1. Design Philosophy and Style REST : REST is an architectural style rather than a protocol. It is based on the principles of statelessness, cacheability, and a uniform interface, leveraging standard HTTP methods like GET, POST, PUT, and DELETE. REST is resource-oriented; each URL represents a resource, typically an object or a service. SOAP : SOAP is a protocol defined by a standard set of rules and has a stricter set of messaging patterns. It focuses on actions and operations rather than resources. SOAP messages are typically wrapped in an XML envelope, which can contain headers and body content. 2. Data Format REST : RESTful services can use various data formats, including JSON, XML, HTML, and plain text, but JSON is the most popular due to its lightweight nature and ease of use with web technologies. SOAP : SOAP exclusively uses XML for sending messages. This can lead to larger message sizes and more parsing overhead compared to JSON. 3. Statefulness REST : REST is stateless; each request from a client to a server must contain all the information needed to understand and complete the request. Statelessness helps in scaling the application as the server does not need to maintain, update, or communicate the session state. SOAP : SOAP can be either stateful or stateless, though it often leans towards stateful operations. This means that SOAP can maintain state across multiple messages or sessions. For the complete list of differences between REST and SOAP APIs, click here to download it. How does REST APIs work? When a RESTful API is called, the server transfers a representation of the state of the requested resource to the requesting client. This information, or representation, is delivered in one of several formats via HTTP: JSON (JavaScript Object Notation), HTML, XLT, Python, PHP, or plain text. JSON is the most popular due to its simplicity and how well it integrates with most programming languages. The client application can then manipulate this resource ( through editing, deleting, or adding information ) and request the server to store this new version. The interaction is stateless, meaning that each request from the client contains all the information the server needs to fulfill that request. 👉It uses HTTP method suitably(GET for getting data, PUT/ PATCH for updating, POST for putting data, DELETE for deleting) 👉Scoping information (and other data) goes in the parameter part of the URL. 👉It uses common data formats like JSON and XML (most commonly used is JSON) 👉Communication is stateless REST API Advantages As we delve into the world of web services and application integration, REST APIs have emerged as a powerful tool. Here are some key benefits: 1. Simplicity and Flexibility Intuitive Design : REST APIs use standard HTTP methods, making them straightforward to understand and implement. This simplicity accelerates development processes. Flexibility in Data Formats : Unlike SOAP which is bound to XML, REST APIs can handle multiple formats like JSON, XML, or even plain text. JSON, in particular, is favored for its lightweight nature and compatibility with modern web applications. 2. Statelessness No Session Overhead : Each request in REST is independent and contains all necessary information, ensuring that the server does not need to maintain session state. This statelessness simplifies server design and improves scalability. Enhanced Scalability and Performance : The stateless nature of REST facilitates easier scaling of applications. It allows servers to quickly free up resources, enhancing performance under load. 3. Cacheability Reduced Server Load : REST APIs can explicitly mark some responses as cacheable, reducing the need for subsequent requests to hit the server. This caching mechanism can significantly improve the efficiency and performance of applications. Improved Client-Side Experience : Effective use of caches leads to quicker response times, directly impacting user experience positively. 4. Uniform Interface Consistent and Standardized : REST APIs provide a uniform interface, making interactions predictable and standardized. This uniformity enables developers to create a more modular and decoupled architecture. Ease of Documentation and Understanding : A standardized interface aids in creating clearer, more concise documentation, which is beneficial for onboarding new team members or integrating external systems. 5. Layered System Enhanced Security : The layered architecture of REST allows for additional security layers (like proxies and gateways) to be introduced without impacting the client or the resource directly. Load Balancing and Scalability : REST's layered system facilitates load balancing and the deployment of APIs across multiple servers, enhancing scalability and reliability. 6. Community and Tooling Support Widespread Adoption : REST's popularity means a large community of developers and an abundance of resources for learning and troubleshooting. Robust Tooling : A plethora of tools and libraries are available for testing, designing, and developing REST APIs, further easing the development process. 7. Platform and Language Independence Cross-Platform Compatibility : REST APIs can be consumed by any client that understands HTTP, making them platform-independent. Language Agnostic : They can be written in any programming language, offering flexibility in choosing technology stacks according to project needs. 8. Easy Integration with Web Services Web-Friendly Nature : REST APIs are designed to work seamlessly in a web environment, taking advantage of HTTP capabilities. Compatibility with Microservices : The RESTful approach aligns well with the microservices architecture, promoting maintainable and scalable system design. REST API Challenges Addressing REST API challenges is crucial for engineering leads and developers who are pivotal in navigating the complexities of API development and integration. Despite the numerous advantages of REST APIs, there are several challenges that teams often encounter. Recognizing and preparing for these challenges is key to ensuring successful implementation and maintenance of RESTful services. REST APIs are stateless; they do not retain information between requests. This can be a hurdle in scenarios where session information is essential. REST APIs typically define endpoints for specific resources. This can lead to overfetching (retrieving more data than needed) or underfetching (needing to make additional requests for more data). Evolving a REST API without breaking existing clients is a common challenge. Proper versioning strategy is essential. Managing the load on the server by implementing rate limiting and throttling is essential but tricky. Poorly implemented throttling can lead to denied services for legitimate users or allow malicious users to consume too many resources. Developing a consistent strategy for error handling and providing meaningful error messages is essential for diagnosing issues. Effectively handling nested resources and relationships between different data entities in a RESTful way can be complex. This may result in intricate URL structures and increased complexity in request handling. Why Choose HyperTest for Testing Your Restful APIs?

Learn how to test event-driven systems effectively using HyperTest. Discover key techniques and tools for robust system testing. 17 March 2025 08 Min. Read How to test Event-Driven Systems with HyperTest? WhatsApp LinkedIn X (Twitter) Copy link Test Queues with HyperTest Modern software architecture has evolved dramatically, with event-driven and microservices-based systems becoming the backbone of scalable applications. While this shift brings tremendous advantages in terms of scalability and fault isolation, it introduces significant testing challenges. Think about it: your sleek, modern application probably relies on dozens of asynchronous operations happening in the background. Order confirmations, stock alerts, payment receipts, and countless other operations are likely handled through message queues rather than synchronous API calls. But here's the million-dollar question (literally, as we'll see later): How confident are you that these background operations are working correctly in production? If your answer contains any hesitation, you're not alone. The invisible nature of queue-based systems makes them notoriously difficult to test properly. In this comprehensive guide, we'll explore how HyperTest offers a solution to this critical challenge. The Serious Consequences of Queue Failures Queue failures aren't merely technical glitches—they're business disasters waiting to happen. Let's look at four major problems users will experience when your queues fail: Problem Impact Real-world Example Critical Notifications Failing Users miss crucial information A customer never receives their order confirmation email Data Loss or Corruption Missing or corrupted information Messages disappear, files get deleted, account balances show incorrectly Unresponsive User Interface Application freezes or hangs App gets stuck in loading state after form submission Performance Issues Slow loading times, stuttering Application becomes sluggish and unresponsive Real-World Applications and Failures Even the most popular applications can suffer from queue failures. Here are some examples: 1. Netflix Problem: Incorrect Subtitles/Audio Tracks Impact: The streaming experience is degraded when subtitle data or audio tracks become out-of-sync with video content. Root Cause: Queue failure between content delivery system (producer) and streaming player (consumer). When your queue fails: Producer:  I sent the message! Broker:  What message? Consumer:  Still waiting... User:  This app is trash. 2. Uber Problem: Incorrect Fare Calculation Impact: Customers get charged incorrectly, leading to disputes and dissatisfaction. Root Cause: Trip details from ride tracking system (producer) to billing system (consumer) contain errors. 3. Banking Apps (e.g., Citi) Problem: Real-time Transaction Notification Failure Impact: Users don't receive timely notifications about transactions. Root Cause: Asynchronous processes for notification delivery fail. The FinTech Case Study: A $2 Million Mistake QuickTrade, a discount trading platform handling over 500,000 daily transactions through a microservices architecture, learned the hard way what happens when you don't properly test message queues. Their development team prioritized feature delivery and rapid deployment through continuous delivery but neglected to implement proper testing for their message queue system. This oversight led to multiple production failures with serious consequences: The Problems and Their Impacts: Order Placement Delays Cause: Queue misconfiguration (designed for 1,000 messages/second but received 1,500/second) Result: 60% slowdown in order processing Impact: Missed trading opportunities and customer dissatisfaction Out-of-Order Processing Cause: Configuration change allowed unordered message processing Result: 3,000 trade orders executed out of sequence Impact: Direct monetary losses Failed Trade Execution Cause: Integration bug caused 5% of trade messages to be dropped Result: Missing trades that showed as completed in the UI Impact: Higher customer complaints and financial liability Duplicate Trade Executions Cause: Queue acknowledgment failures Result: 12,000 duplicate executions, including one user who unintentionally purchased 30,000 shares instead of 10,000 Impact: Refunds and financial losses The Total Cost: A staggering $2 million in damages, not counting the incalculable cost to their reputation. Why Testing Queues Is Surprisingly Difficult? Even experienced teams struggle with testing queue-based systems. Here's why: 1. Lack of Immediate Feedback In synchronous systems, operations usually block until completion, so errors and exceptions are returned directly and immediately. Asynchronous systems operate without blocking, which means issues may manifest much later than the point of failure, making it difficult to trace back to the origin. Synchronous Flow: Operation → Result → Error/Exception Asynchronous Flow: Operation → (Time Passes) → Delayed Result → (Uncertain Timing) → Error/Exception 2. Distributed Nature Message queues in distributed systems spread across separate machines or processes enable asynchronous data flow, but they make tracking transformations and state changes challenging due to scattered components. 3. Lack of Visibility and Observability Traditional debugging tools are designed for synchronous workflows, not asynchronous ones. Proper testing of asynchronous systems requires advanced observability tools like distributed tracing to monitor and visualize transaction flows across services and components. 4. Complex Data Transformations In many message queue architectures, data undergoes various transformations as it moves through different systems. Debugging data inconsistencies from these complex transformations is challenging, especially with legacy or poorly documented systems. Typical developer trying to debug queue issues: End-to-End Integration Testing with HyperTest Enter HyperTest: a specialized tool designed to tackle the unique challenges of testing event-driven systems. It offers four key capabilities that make it uniquely suited for testing event-driven systems: 1.

End-to-End Testing of Producers and Consumers HyperTest monitors actual calls between producers and consumers, verifying that: Producers send the right messages to the broker Consumers perform the right operations after receiving those messages And it does all this 100% autonomously, without requiring developers to write manual test cases. 3. Distributed Tracing HyperTest tests real-world async flows, eliminating the need for orchestrating test data or environments. It provides complete traces of failing operations, helping identify and fix root causes quickly. 4. Automatic Data Validation HyperTest automatically asserts both: Schema : The data structure of the message (strings, numbers, etc.) Data : The exact values of the message parameters Testing Producers vs. Testing Consumers Let's look at how HyperTest handles both sides of the queue equation: ✅ Testing Producers Consider an e-commerce application where OrderService sends order information to GeneratePDFService to create and store a PDF receipt. HyperTest Generated Integration Test 01: Testing the Producer In this test, HyperTest verifies if the contents of the message sent by the producer (OrderService) are correct, checking both the schema and data. OrderService (Producer) → Event_order.created → GeneratePDFService (Consumer) → PDF stored in SQL HyperTest automatically: Captures the message sent by OrderService Validates the message structure (schema) Verifies the message content (data) Provides detailed diff reports of any discrepancies ✅ Testing Consumers HyperTest Generated Integration Test 02: Testing the Consumer In this test, HyperTest asserts consumer operations after it receives the event. It verifies if GeneratePDFService correctly uploads the PDF to the data store. OrderService (Producer) → Event_order.created → GeneratePDFService (Consumer) → PDF stored in SQL HyperTest automatically: Monitors the receipt of the message by GeneratePDFService Tracks all downstream operations triggered by that message Verifies that the expected outcomes occur (PDF creation and storage) Reports any deviations from expected behavior Implementation Guide: Getting Started with HyperTest Step 1: Understand Your Queue Architecture Before implementing HyperTest, map out your current queue architecture: Identify all producers and consumers Document the expected message formats Note any transformation logic Step 2: Implement HyperTest HyperTest integrates with your existing CI/CD pipeline and can be set up to: Automatically test new code changes Test interactions with all dependencies Generate comprehensive test reports Step 3: Monitor and Analyze Once implemented, HyperTest provides: Real-time insights into queue performance Automated detection of schema or data issues Complete tracing for any failures Benefits Companies Are Seeing Organizations like Porter, Paysense, Nykaa, Mobisy, Skuad, and Fyers are already leveraging HyperTest to: Accelerate time to market Reduce project delays Improve code quality Eliminate the need to write and maintain automation tests "Before HyperTest, our biggest challenge was testing Kafka queue messages between microservices. We couldn't verify if Service A's changes would break Service B in production despite our mocking efforts. HyperTest solved this by providing real-time validation of our event-driven architecture, eliminating the blind spots in our asynchronous workflows." -Jabbar M, Engineering Lead at Zoop.one Conclusion As event-driven architectures become increasingly prevalent, testing strategies must evolve accordingly.

Explore the inherent challenges in manual testing, from time-consuming processes to scalability issues. Learn how to navigate and overcome the top obstacles for more efficient and effective testing. 1 February 2024 09 Min. Read Top Challenges in Manual Testing WhatsApp LinkedIn X (Twitter) Copy link Download The Comparison Sheet The software development lifecycle (SDLC) has undergone significant evolution, characterized by shorter development sprints and more frequent releases. This change is driven by market demands for constant readiness for release. Consequently, the role of testing within the SDLC has become increasingly critical. In today's fast-paced development environment, where users expect regular updates and new features, manual testing can be a hindrance due to its time-consuming nature. This challenge has elevated the importance of automation testing, which has become indispensable in modern software development practices. Automation testing efficiently overcomes the limitations of manual testing, enabling quicker turnaround times and ensuring that software meets the high standards of quality and reliability required in the current market. In this blog, we will delve into the various challenges associated with manual testing of applications. While manual testing is often advisable for those at the beginning stages of development or operating with limited budgets, it is not a sustainable long-term practice. This is particularly true for repetitive tasks, which modern automation tools can handle more efficiently and effectively. What is Manual Testing? Manual testing is a process in software development where testers manually operate a software application to detect defects or bugs. Unlike automated testing, where tests are executed with the aid of scripts and tools, manual testing involves human input, analysis, and insights. Key aspects of manual testing include: Human Observation : Crucial in detecting subtle issues like user interface defects or usability problems, which automated tests might miss. Test Case Execution : Testers follow a set of predefined test cases but also use exploratory testing, where they deviate from these cases to identify unexpected behavior. Flexibility : Testers can quickly adapt and change their approach based on the application's behavior during the testing phase. Understanding User Perspective : Manual testers can provide feedback on the user experience, which is particularly valuable in ensuring the software is user-friendly and meets customer expectations. Cost-Effectiveness for Small Projects : For small-scale projects or when the testing requirements are constantly changing, manual testing can be more cost-effective than setting up automated tests. No Need for Test Script Development : This saves time initially, as there is no need to write scripts, unlike in automated testing. Want to perform automated testing without putting any efforts in writing test scripts? Identifying Visual Issues : Manual testing is more effective in identifying visual and content-related issues, such as typos, alignment issues, color consistency, and overall layout. What’s the Process of Manual Testing? Manual testing is a fundamental aspect of software development that involves a meticulous process where testers evaluate software manually to find defects. The process can be both rigorous and insightful, requiring a combination of structured test procedures and the tester's intuition. Let's break down the typical stages involved in manual testing: Understanding Requirements : The process begins with testers gaining a thorough understanding of the software requirements. This includes studying the specifications, user documentation, and design documents to comprehend what the software is intended to do. Test Plan Creation : Based on the understanding of requirements, testers develop a test plan. This plan outlines the scope, approach, resources, and schedule of intended test activities. It serves as a roadmap for the testing process. Test Case Development : Testers then create detailed test cases. These are specific conditions under which they will test the software to check if it behaves as expected. Test cases are designed to cover all aspects of the software, including functional, performance, and user interface components. Example Test Case: - Test Case ID: TC001 - Description: Verify login with valid credentials - Precondition: User is on Login Page - Steps: 1. Enter valid username 2. Enter valid password 3. Click on Login button - Expected Result: User is successfully logged in and directed to the dashboard Setting up the Test Environment : Before actual testing begins, the appropriate test environment is set up. This includes hardware and software configurations on which the software will be tested. Test Execution : During this phase, testers execute the test cases manually. They interact with the software, inputting data, and observing the outcomes to ensure that the software behaves as expected in different scenarios. Defect Logging : If a tester encounters a bug or defect, they log it in a tracking system. This includes detailed information about the defect, steps to reproduce it, and screenshots if necessary. Retesting and Regression Testing : Once defects are fixed, testers retest the software to ensure that the specific issue has been resolved. They also perform regression testing to check if the new changes haven’t adversely affected existing functionalities. Perform regression testing with ease with HyperTest and never let a bug leak to production! Know about the approach now! Reporting and Feedback : Testers prepare a final report summarizing the testing activities, including the number of tests conducted, defects found, and the status of the software. They also provide feedback on software quality and suggest improvements. Test Summary Report: - Total Test Cases: [Number] - Passed: [Number] - Failed: [Number] - Defects Found: [Number] - Recommendations: [Any suggestions or feedback] Final Validation and Closure : The software undergoes a final validation to ensure it meets all requirements. Upon successful validation, the testing phase is concluded. The process of manual testing is iterative and may cycle through these stages multiple times to ensure the software meets the highest standards of quality and functionality. It requires a keen eye for detail, patience, and a deep understanding of both the software and the user's perspective. How Manual Testing is different from Automation Testing? Manual testing and automation testing are two distinct approaches in software testing, each with its own set of characteristics and uses. Since we’ve already explored the concept of manual testing above, let's first understand the concept of automation testing and then move ahead with the differences. Automation Testing: Automation testing uses software tools and scripts to perform tests on the software automatically. This approach is ideal for repetitive tasks and can handle large volumes of data. Speed and Efficiency : Automated tests can be run quickly and repeatedly, which is a significant advantage for large projects. Accuracy : Reduces the risk of human error in repetitive and detailed test cases. Cost-Effective in the Long Run : While the initial investment is higher, it's more cost-effective for long-term projects. Non-UI Related Testing : Better suited for non-user interface testing such as load testing, performance testing, etc. Requires Technical Skills : Knowledge of scripting and programming is necessary to write test scripts. For better clarity, here’s a comparison table between the two types of testing: Aspect Manual Testing Automation Testing Execution Performed by human testers Performed by tools and scripts Time-Consumption Time-consuming, especially for large-scale testing Faster, can run tests repeatedly Cost Initially less costly, more for long-term Higher initial cost, but cheaper long-term Accuracy Prone to human error in repetitive tasks High accuracy, minimal human error Suitability Ideal for exploratory, usability, and ad-hoc testing Best for regression, load, and performance testing Technical Skills Required Generally not required Requires programming knowledge Flexibility More flexible in test design and execution Less flexible, requires predefined scripts Feedback on User Experience Better at assessing visual and user experience aspects Does not assess user experience Top Challenges in Manual Testing Manual testing, while essential in many scenarios, faces several key challenges. These challenges can impact the effectiveness, efficiency, and overall success of the testing process. Here we are going to discuss the most prominent challenges in manual testing as faced by majority of testers. Time-Consuming and Labor-Intensive Manual testing requires significant human effort and time, especially for large and complex applications. Consider manual testing in a retail banking application. The application's vast array of features means a significant number of test cases need to be executed. For example , just the fund transfer feature might include test cases for different types of transfers, limits, recipient management, transaction history, etc. Human Error Due to its repetitive nature, manual testing is prone to human error. Testers may miss out on executing some test cases or fail to notice some bugs. Consider a scenario where a tester needs to verify the correctness of user input fields across multiple forms. Missing even a single validation, like an email format check, can lead to undetected issues. Example Missed Test Case: - Test Case ID: TC105 - Description: Validate email format in registration form - Missed: Not executed due to oversight Difficulty in Handling Large Volume of Test Data Managing and testing with large datasets manually is challenging and inefficient. For instance, manually testing database operations with thousands of records for performance and data integrity is not only tedious but also prone to inaccuracies. Example: Healthcare Data Management System A healthcare data management system needs to manage and test thousands of patient records. The manual testing team might struggle to effectively validate data integrity and consistency, leading to potential risks in patient data management. Inconsistency in Testing Different testers may have varied interpretations and approaches, leading to inconsistencies in testing. For example, two testers might follow different paths to reproduce a bug, leading to inconsistent bug reports. For example, inconsistencies might come when testing a mobile app for delivery services, leading to varied bug reports and confusion. A particular testing team might report an issue with the GPS functionality, while another might not, depending on their approach and device used. Documentation challenges Comprehensive documentation of test cases and defects is crucial but can be burdensome. Accurately documenting the steps to reproduce a bug or the test case execution details demands meticulous attention. Bug Report Example: - Bug ID: BUG102 - Description: Shopping cart does not update item quantity - Steps to Reproduce: 1. Add item to cart 2. Change item quantity in cart 3. Cart fails to show updated quantity - Status: Open Difficulty in Regression Testing With each new release, regression testing becomes more challenging in manual testing, as testers need to re-execute a large number of test cases to ensure existing functionalities are not broken. Lets say you’re performing manual testing of a financial analytics tool since a new feature is added to the app. You need to perform manual testing for all the existing functionalities to check its compatibility with this new feature. This repetitive process can become increasingly burdensome over time, slowing down the release of new features. Limited Coverage Achieving comprehensive test coverage manually is difficult, especially for complex applications. Testers might not be able to cover all use cases, user paths, and scenarios due to time and resource constraints. Manually testing an ever-expanding application is increasingly impractical, especially when trying to meet fast-paced market demands. Complex applications often feature thousands, or even lakhs, of interconnected services, resulting in a multitude of possible user flows. Attempting to conceive every possible user interaction and subsequently creating manual test scripts for each is an unrealistic task. This often leads to numerous user flows being deployed to production without adequate testing. As a result, untested flows can introduce bugs into the system, necessitating frequent rollbacks and emergency fixes. This approach not only undermines the software's reliability but also hinders the ability to swiftly and efficiently respond to market needs. Tired of manually testing your half-found user-flows? Get rid of this and achieve up to 95% test coverage without ever writing a single line of code. See it working here. Conclusion In conclusion, manual testing remains a critical component in the software testing landscape, offering unique advantages in terms of flexibility, user experience assessment, and specific scenario testing. However, as we have seen through various examples and real-world case studies, it comes with its own set of challenges. These include being time-consuming and labor-intensive, especially for complex applications like retail banking software, susceptibility to human error, difficulties in managing large volumes of test data, limited scope for non-functional testing, and several others.

Discover why integration testing is essential for software development success. Explore key benefits and best practices. 2 July 2024 07 Min. Read Reasons Why Integration Testing is Crucial? WhatsApp LinkedIn X (Twitter) Copy link Download the Checklist Know why integration testing is crucial? Let’s come directly to the point. ➡️Think of a ride-hailing app like Uber or Lyft. They rely on multiple interacting components: User interface: Users interact with the app to request rides. Location services: The app tracks user location and finds available drivers. Routing algorithms: The app calculates the optimal route for the driver. Payment gateway: Users pay for rides through the app. What role did integration testing play here? Integration testing ensures these components work seamlessly together . This involves verifying: Data flow: User location data is accurately transmitted to the routing algorithm. Response times: Drivers receive ride requests promptly, and users experience minimal delays. Error handling: The system gracefully handles situations like unavailable drivers or unexpected location issues. The Importance of Integration Testing Embracing integration testing with a modern approach is the definitive solution to overcoming the challenges associated with traditional methods. By validating the interaction between various components, modules, and services, integration testing goes beyond the confines of unit tests. It simulates real-world scenarios, including interactions with databases, APIs, and external services, to uncover bugs that may only manifest under specific conditions. 💡 A study by Infosys found that integration defects are 4-5 times more expensive to fix compared to unit-level defects. Integration testing plays a pivotal role in identifying and resolving integration issues early in the development process. It ensures end-to-end validation of critical workflows and user journeys, instilling confidence in the code changes made by developers. Moreover, by automating integration tests and integrating them into the CI/CD pipeline , developers can validate changes early and often, facilitating smoother deployments. Benefits of Integration Testing By validating the interaction between different components, modules, and services within an application, integration testing helps developers deliver robust, high-quality software with greater confidence and efficiency. Let's explore some of the key benefits of integration testing. 1. Ensures Component Compatibility Integration testing is essential for verifying that different components of an application are compatible with each other. 💡 This involves ensuring that data formats, interfaces, and communications between components are correctly implemented. Example: Suppose your application integrates a third-party payment gateway and your own user account management system. Integration testing helps verify that users can successfully make payments through their accounts without issues, catching compatibility issues early. # Example integration test for payment through user accounts def test_user_payment_integration(): user_account = create_test_user_account() payment_response = make_payment_through_gateway(user_account, amount=100) assert payment_response.status == 'Success' 2. Detects Interface Defects Example: Testing the interaction between the front-end UI and the back-end database can reveal issues with data retrieval or submission that unit tests might not catch, such as improperly handled query parameters. // Example integration test for front-end and back-end interaction describe("User profile update", () => { it("should update the user's profile information in the database", async () => { const user = await createUserWithProfile({name: 'John Doe', age: 30}); const updatedInfo = {name: 'John Doe', age: 31}; await updateUserProfile(user.id, updatedInfo); const updatedUser = await getUserById(user.id); expect(updatedUser.age).toEqual(31); }); }); 3. Validates End-to-End Functionality Example: An end-to-end test might simulate a user's journey from logging in, performing a task, and logging out, thereby ensuring the application behaves as expected across different modules. # Example end-to-end integration test def test_user_workflow_end_to_end(): login_success = login_user('testuser', 'correctpassword') assert login_success is True task_creation_success = create_user_task('testuser', 'Complete integration testing') assert task_creation_success is True logout_success = logout_user('testuser') assert logout_success is True 4. Facilitates Early Detection of Problems Detecting and solving problems early in the development process is less costly than fixing issues discovered later in production. Integration testing helps identify and address integration and interaction issues before the deployment phase. Imagine an e-commerce platform where the shopping cart functionality is built and tested independently of the payment processing system. Unit testing might ensure each component works internally, but integration testing is crucial. Without it, issues like: Incorrect data exchange: The shopping cart might send product details with different formatting than expected by the payment gateway, causing transaction failures. Make sure that you don’t end up becoming a victim of such data failures, implement the right solution now. Communication problems: The network connection between the e-commerce platform and the payment gateway might be unstable, leading to timeouts and order processing delays. Logic conflicts: Discounts applied in the shopping cart might not be reflected in the final payment amount calculated by the payment gateway. 💡  In 2012, a major bank outage occurred due to an integration issue between a core banking system and a new fraud detection module. Thorough integration testing could have prevented this widespread service disruption. 5. Efficient Debugging Process Imagine a social media platform where users can post updates and interact with each other. Issues with integration points can be complex to diagnose. Integration testing helps pinpoint the exact problem location: Is the issue with the user interface module not sending data correctly? Is the user data being misinterpreted by the backend server? Is there a communication failure between the different servers hosting the platform? By isolating the issue within specific modules through integration testing, developers can save significant time and effort compared to troubleshooting isolated units. 6. Reduces Risks and Increases Confidence By thoroughly testing the integration points between components, engineering teams can be more confident in the stability and reliability of the software product, reducing the risk of failures in production environments. Imagine a large hospital information system with modules for patient records, appointment scheduling, and lab results. Integration testing helps ensure these modules work together flawlessly: 1. Patient information entered in one module should consistently appear in others. 2. Appointments scheduled in one module should not conflict with existing appointments. 3. Lab results should be readily accessible within the patient record module. Successful integration testing builds confidence in the overall system's functionality. When developers need to modify or introduce new features, they can rely on well-tested integration points, making maintenance and future development smoother. 7. Improves Team Collaboration Integration testing requires communication and collaboration between different members of a development team, such as developers, QA engineers, and system administrators, fostering a more cohesive and efficient team environment. Overall, integration testing is essential for developers as it helps ensure seamless communication between different components, detects and resolves integration issues early, validates the interoperability of different modules, and reduces the risk of regression and system failures. By incorporating integration testing into the development process, developers can deliver high-quality software that meets the needs and expectations of users. Best Practices for Integration Testing Integration testing plays a crucial role in software development by ensuring seamless communication between various components, modules, and services within an application. It goes beyond the scope of unit testing and validates the interaction between different parts of the codebase. In this section, we will explore the best practices for integration testing that can empower developers to deliver robust and high-quality software with greater confidence and efficiency. 💡 A study by Capgemini revealed that automated integration testing can improve test coverage by up to 70%, leading to faster development cycles and reduced costs. ✅ Establishing a comprehensive test environment One of the key aspects of integration testing is setting up a dedicated test environment that includes all the necessary dependencies. This environment should accurately simulate the production environment, including message queues, databases, and other external services. By replicating the real-world conditions, developers can thoroughly test the integration points and identify any potential issues that may arise when the application is deployed. ✅ Defining clear test objectives and scenarios To ensure effective integration testing, it is essential to define clear test objectives and scenarios. This involves identifying the critical workflows and user journeys that need to be tested. By focusing on the end-to-end user scenarios, developers can validate that the application functions correctly and delivers the expected results. Clear test objectives and scenarios provide a roadmap for testing and help prioritize the areas that require thorough validation. ✅ Designing test cases to cover different integration scenarios Designing comprehensive test cases is a critical step in integration testing. Test cases should cover different integration scenarios, including interactions with databases, APIs, and external services. By testing the application in a realistic environment, developers can uncover potential bugs that may only manifest under specific conditions. It is important to design test cases that validate the integration points and ensure that the code functions seamlessly as a unified whole. ✅ Implementing test automation for efficient and effective testing Test automation is an essential practice for efficient and effective integration testing. Automating the testing process helps save time, reduce human errors, and ensure consistent results. By leveraging tools like HyperTest, developers can automatically generate and run integration tests, simulate dependencies with intelligent mocks, and identify issues early through shift-left testing. Test automation allows developers to focus on coding and innovation while ensuring that the application meets the desired quality standards. ✅ Analyzing and reporting test results for continuous improvement Analyzing and reporting test results is a crucial step in the integration testing process. It provides valuable insights into the performance and reliability of the application. By analyzing test results, developers can identify areas that require improvement, detect integration issues such as data inconsistencies or communication failures, and address them proactively. Continuous improvement is an iterative process, and analyzing test results plays a vital role in enhancing the overall quality of the software. Conclusion In conclusion, integration testing plays a pivotal role in ensuring the delivery of high-quality software products. It helps engineering teams identify and address issues early, facilitates smoother integrations between components, and ultimately leads to a more reliable and robust application. Emphasizing the importance of integration testing within your team can lead to more successful project outcomes and satisfied customers. Related to Integration Testing Frequently Asked Questions 1.

Master end-to-end testing! This guide shows you how to design tests for real user flows, manage test data, and automate effectively. 20 June 2024 14 Min. Read End-to-End Testing: A Detailed Guide WhatsApp LinkedIn X (Twitter) Copy link Checklist for best practices 💡 I am a senior SWE at a large tech company. I started on a legacy tool that has multiple repos (frontend, backend, and some other services) and has no automated interface testing. We do have a QA team that runs through scenarios, but that's error prone and expensive. In reality, a lot of our defects are encountered by users in prod ( sad ). I have had mixed experience with e2e testing in the past: challenging to maintain with a lot of moving parts, sometimes flakey, challenging to coordinate between repos moving at different speeds. Relatable, right? That’s the story of every other SWE! E2E tests are good only when they’re working correctly and navigating the actual failure instead of any other broken parts. But this is not a guide to tell the reality-check of E2E tests. INSTEAD, this guide is here to tell you everything about End-to-end tests. We’re not going to discuss only about the positive and how-to sides of this top segment of the testing pyramid . This is more like a raw version of everything E2E, which talks both about the + and - of it. End-to-End testing: The most debatable part of the pyramid E2E tests are the ones that tests your whole app in one go. Interesting? Superficially, yes! But when you dig deep and gain more knowledge on this, you’ll also find yourself debating about keeping it or leaving it within your team. A formal introduction on E2E tests⬇️: End-to-end testing is a method of testing the entire software application from start to finish. The goal is to validate the system as a whole and ensure that all integrated components work together as expected. E2E testing simulates real user scenarios to identify any issues with the system's interaction and data integrity across different layers. Basically, E2E tests can test your system under two conditions: all your services, databases and other dependent components need to be kept up and running: Simulating a live scenario mocking or stubbing any external dependencies as per your convenience to allow for controlled and repeatable testing Why is end-to-end testing important? 1. Covers the Entire Application: End-to-end testing checks the entire flow of an application from start to finish. It ensures all parts of the system work together as expected, from the user interface down to the database and network communications. 2. Detects System-Level Issues: E2E helps identify issues that might not be caught during unit testing or integration testing , such as problems with data integrity, software interactions, and overall system behavior. 3. Mimics Real User Scenarios: It simulates real user experiences to ensure the application behaves correctly in real-world usage scenarios. This helps catch unexpected errors and improves user satisfaction. The Benefits of End-to-End testing In an ideal scenario when E2E test is running smoothly and finding the right defects and bugs, it has potential to offer tremendous help: E2E can often be the most straightforward or apparent way to add testing to an existing codebase that’s missing tests. When it's working, it gives a lot of confidence when you have your most important use cases covered. E2E tests for basic sanity checks (i.e. just that a site loads and the page isn’t blank) is very useful and are always good to have. Key Components of End-to-End Testing 💡 Yes, E2E can be flaky, yes they can be annoying to keep up to date, yes their behavior can be harder to define, yes they can be harder to precisely repro. However, they can test behavior which you can't test otherwise. Steps in End-to-End Testing 💡 Writing a  couple  of e2e (UI) tests is ok though. The key is to not overdo it. E2E tests are really complex to maintain. Requirement Analysis : Understand the application requirements and user workflows. Test Planning : Define the scope, objectives, and approach for E2E testing. Test Design : Create detailed test scenarios and test cases. Test Environment Setup : Prepare the test environment to mimic production. Test Execution : Run the test scenarios using automated tools. Test Reporting : Document the results and identify any defects. Defect Retesting : Fix and retest any identified defects. Regression Testing : Ensure new changes do not affect existing functionality. Example of End-to-End Testing Consider an application with a user authentication system. An E2E test scenario might include: User Signup : Navigate to the signup page, fill out the form, and submit. Form Submission : Submit the signup form with user details. Authentication : Verify the authentication process using the provided credentials. Account Creation : Ensure the account is created and stored in the database. Login Service : Log in with the newly created account and verify access. Types of End-to-End Testing There are two types of End-to-End Testing: Vertical E2E testing and horizontal E2E testing. Each type serves a different purpose and approach. Let’s have a quick look at both: ⏩Vertical E2E Testing Vertical E2E testing focuses on testing a complete transaction or process within a single application. This type of testing ensures that all the layers of the application work together correctly. It covers the user interface (UI), backend services, databases, and any integrated systems. Example: Consider a banking application where a user transfers money. Vertical E2E testing would cover: User logs into the application. User navigates to the transfer money section. User enters transfer details and submits the request. The system processes the transfer. The transfer details are updated in the user’s account. ⏩Horizontal E2E Testing Horizontal E2E testing spans multiple applications or systems to ensure that they work together as expected. This type of testing is important for integrated systems where different applications interact with each other. Example: Consider an e-commerce platform with multiple integrated systems. Horizontal E2E testing would cover: User adds a product to the shopping cart on the website. The cart service communicates with the inventory service to check stock availability. The payment service processes the user's payment. The order service confirms the order and updates the inventory. The shipping service arranges for the product delivery. Best Practices for End-to-End Testing Implementing E2E testing effectively requires following best practices to ensure thorough and reliable tests. Here are some key practices to consider: E2E tests hitting API endpoints tend to be more useful than hitting a website. This is because it tends to break less, be more reliable, and easier to maintain. Focus on the most important user journeys. Prioritize scenarios that are critical to the business and have a high impact on users. E2E tests on an existing codebase often requires ALOT of test setup, and that can be very fragile. If E2E testing takes a lot of work to get setup, then chances it will become easily broken, as people develop. This will become a constant burden on development time. If your E2E tests aren’t automated and lots of manual steps to run them. Then they won’t get used, and development will be painful. Ideally you’d want to be able to run your tests with 1 or 2 direct commands with everything automated. Set up a test environment that mimics production but is isolated from it. This prevents tests from affecting live data and services. If your E2E tests have any unreliability, then they will be ignored by developers on the build system. If they aren’t actively worked on, they will eventually get disabled. Test data should be as close to real-world data as possible. This helps in identifying issues that users might face in a production environment. 💡 Eliminate the problem of test-data preparation while performing E2E tests cases, ask us how Regularly update and maintain test scripts to reflect changes in the application. This ensures that the tests remain relevant and effective. If your E2E tests take longer to write and run than unit tests, than they will become unmaintainable. By following these best practices, you can ensure that your E2E testing is thorough, efficient, and effective in identifying and resolving issues before they reach your users. Challenges with End to End Testing Well, here’s the part finally why I narrowed down to write on this topic. Since I started on a negative side about E2E testing and then continued with all the positives and how-to things, I assume you might be confused by this time? Whether E2E testing is a good practice to invest in or should the fast moving teams of today should leave it as it is? Here’s the breakdown of some challenges that are worth to talk about before you make your decision to go ahead with E2E testing. Extremely difficult to write, maintain and update . While End-to-End (E2E) tests mimicking real user interaction can expose integration issues between services, the cost of creating and maintaining such tests, especially for complex systems with numerous services, can be very high due to the time and effort involved. imprecise because they've such a broad scope needs the entire system up & running, making it slower and difficult to identify the error initiation point E2E testing might be overkill for this minor issue{user}→{users}. It requires all services to be operational, and even then, there's a chance it might not pinpoint the exact cause. It could potentially flag unrelated, less critical problems instead. Tools for End-to-End Testing ⏩HyperTest Before we start, we don’t do E2E testing! But we are capable of providing the same outcomes as you expect from an E2E test suite.

It simplifies E2E testing with a user-friendly interface. ⏩Testim An AI-powered E2E testing tool that helps create, execute, and maintain automated tests. Conclusion While E2E tests offer comprehensive system checks, they're not ideal for pinpointing specific issues. They can be unreliable (flaky), resource-intensive, and time-consuming. Therefore, focus on creating a minimal set of E2E tests. Their true value lies in exposing gaps in your existing testing strategy. Ideally, any legitimate E2E failures should be replicated by more focused unit or integration tests. Try HyperTest for that. Here's a quick guideline: Minimize: Create only the essential E2E tests. Maximize frequency: Run them often for early error detection. Refine over time: Convert E2E tests to more targeted unit/integration tests or monitoring checks whenever possible. Related to Integration Testing Frequently Asked Questions 1. What does e2e mean? E2E stands for "end-to-end." It refers to a method that checks an application's entire functionality, simulating real-world user scenarios from start to finish. 2. Is selenium a front-end or backend? E2E testing can face a few challenges: - Maintaining consistent and realistic test data across different testing environments can be tricky. - Testing across multiple systems and integrations can be complex and time-consuming, requiring specialized skills. - Tests might fail due to external factors or dependencies, making them unreliable (flaky). 3. Are E2E and integration testing the same? No, E2E and integration testing are distinct. Integration testing focuses on verifying how individual software components interact with each other. E2E testing, on the other hand, simulates real user journeys to validate the entire application flow. For your next read Dive deeper with these related posts! 09 Min.

Discover the challenges of using Playwright for web application testing and learn best practices to overcome them. 23 July 2024 09 Min. Read Using Playwright? Here Are the Challenges You Need to Know WhatsApp LinkedIn X (Twitter) Copy link Get the Comparison Sheet Developers nowadays face challenges like “ Lot fewer examples/documentation out there on how to "structure" the framework ” or “challenge of initializing the page beans in parallel run”. However, they are not just the challenges in using Playwright being encountered, there are others too that require to be addressed. In this article, we will be discussing those challenges that you need to know about Playwrights. Along with this, we will also highlight some best practices of Playwright testing to overcome the challenges. So let us get started, but first, let us give you a brief on Playwright. What is Playwright? Playwright is an open source and freely available automation testing framework developed by Microsoft. It framework is very beneficial for developer as it allows to test web application from start to finish with different coding preferences. This is because Playwright support for various programming languages like JavaScript, TypeScript, Python, C#, and Java. But what exactly make Playwright different from other testing tool? The playwright distinguishes itself by automating browsers like Chromium, Firefox, and WebKit; with just one API, you can perform cross-browser testing and ensure your web applications perform flawlessly across different platforms. Features of Playwright Playwright is new to the market, and just having its overview is not just enough. To take full advantage of Playwright testing, you must be aware of its key features. Let us know about those: Cross-browser Testing: It can test seamlessly across various browser engines like Chromium, Firefox, and WebKit. Auto-wait feature: This ensures that elements of software application are ready before executing actions, minimizing potential test failures due to flakiness. Network Interception: Playwright enables the monitoring and alteration of network requests, which helps in executing Playwright testing across various network scenarios and API interactions. Headless Mode: It has the capability to operate browsers in headless mode, a necessary feature for executing tests in CI/CD pipelines without a graphical user interface. Strong Selectors: Playwright offers strong selector engines, simplifying the process of finding elements on web pages for interactions. “Although Playwright for executing tests offers several key advantages like easy setup, multi-browser support, parallel browser testing, etc. It is important to first understand the challenges of using Playwright” Challenges of Using Playwright Addresing the challenges of using Playwright will help you to ensure seamless integration, effective debugging, and improved performance. Further, it can help developers fully leverage Playwright's capabilities, resulting in more reliable test automation. So let us dive deep into detail in knowing about those challenges: Challenge 1: Support For Protocols Other Than Browsers is Limited. Playwright's support is limited to HTTP/HTTPS and browser-specific protocols like data: and blob:. It cannot handle FTP, file downloads, or other non-browser protocols. This restriction means that while Playwright good in automating and testing web applications, it is unsuitable for tasks requiring interaction with non-browser protocols. You should consider alternative tools for comprehensive testing needs involving FTP or file downloads. Challenge 2: Lack of Native Watch Mode It does not have a pre-installed feature for monitoring changes done during Playwright testing. This impact the development workflow and Playwright testing process more complicated. It is because of need of manual configuration and upkeep of extra tools or scripts to monitor file changes effectively. Although Playwright is effective for browser automation and testing, its dependency on external libraries for detecting changes can hamper smooth integration and immediate responsiveness when conducting automated tests. Challenge 3: Environment Files Are Not Natively Supported. Playwright does not have native support for reading environment files. Developers often turn to external tools like “ dotenv ” to interpret JSON or other formats, adding an extra task to the development process. You can often face problems in the set-up process because it requires the manual incorporation of external libraries to manage environment configuration when you perform automated testing and development activities. Challenge 4: The Limitations of Unit Testing for Playwrights. Developers should be aware that Playwright is not suitable for unit testing because it prioritizes end-to-end testing and browser automation. You must be knowing that unit testing often needs a framework like Jest in JavaScript designed for testing individual, confined sections of code. However, when you will be using Playwright for unit testing, it could add unnecessary complexity and overhead since it is designed for higher-level testing instead of the specific, detailed focus needed for unit tests. Challenge 5: Asynchronous Execution in Playwright Another crucial challenge in Playwright testing is that the tool fails to work in an asynchronous manner, potentially causing difficulties for developers not accustomed to asynchronous programming. This complexity can heighten the learning curve and create challenges in writing, maintaining, and troubleshooting tests. Challenge 6: Challenges in Finding Solutions with Playwright The bug or issue identified during the Playwright testing can be difficult to fix. You may wonder why this is so. Well, the Playwright lacks extensive resources and robust community support. This can lead to longer troubleshooting times and fewer readily available solutions for complex issues found in software application. Challenge 7: Unsupported Features Playwright, being a recently developed library, does not have official backing for some capabilities, such as configuring local storage. Although there are ways to work around them, depending on these methods can make the development process more complex. Developers might have to create their own solutions or try different approaches in order to achieve the desired functionality, potentially leading to higher code complexity and maintenance tasks. Challenge 8: Integration with CI/CD Pipelines Integrating Playwright into the CI/CD pipeline in different environments like Jenkins and Gitlab CI is another crucial challenge faced by everyone. You can think of this due to diverse setup requirements such as configuring environment variables, handling dependencies, guaranteeing consistent browser versions, and establishing necessary permissions for browser access and test execution. Challenge 9: Handling Complicated DOM Layouts It is crucial to note that Playwright is capable of manipulating and interacting with web elements. However, developers often face issues when dealing with complex and constantly changing DOM structures when using Playwright. Hence, when they execute Playwright testing, the test script may have difficulty finding and interacting with elements that are deeply buried in complex DOM trees or dynamically load after page interactions. This could result in unreliable tests or necessitate complex scripting workarounds to manage properly. Challenge 10: Identifying and Troubleshooting Unstable Tests. Recognizing and fixing flaky tests, which fail irregularly with no modifications to the application or test code, is a major challenge in Playwright. For developers, getting a flaky test is problematic because it not only undermines the trust in automation results but also consumes developer hours in troubleshooting unpredictable problems and impacts timely responses to software changes. Best Practice To Overcome Challenges In Using Playwright Challenges in using Playwright are not exceptional issues, as different automation testing frameworks also come with key limitations. The most important part here is to address those challenges so they do not impact the test process and result. Here are some of the best practices of Playwright testing that could help you leverage the true capability of a Playwright and overcome the challenges discussed: Set your test coverage objectives from the start. Before you start creating end-to-end (E2E) tests for your application, it is important to identify the main workflows that need to be tested. You must concentrate on user experience and user interaction or use an analytical tool that can show the most visited URL, and devices and browsers frequently being used. This give idea on deciding which aspect of app needs to be tested. Utilize consistent selectors for identifying elements. In order to test the functionality of your web application, you must locate elements on the page and interact with them. Playwright promotes the use of its predefined locators to choose the elements that you want to interact with. Automate your tests and keep track of them . Testing only on your personal computer is not enough for a strong development process. It is important to incorporate them into your CI/CD workflows in order to track them together with your builds. Avoid testing third-party integrations. It is recommended to refrain from directly testing third-party interfaces in your end-to-end tests. Instead of that, use the Playwright Network API to mock these external services. This method allows you to replicate the precise functioning of these connections, ensuring that your tests stay speedy and reliable, regardless of how well the third-party services are performing or their accessibility. You can also opt for HyperTest which facilitates testing by mocking all third-party dependencies, including databases, message queues, and sockets, as well as dependent services. This approach enables each service to undergo testing independently, even in intricate environments with high interdependence among services. By mocking external dependencies, HyperTest ensures tests can concentrate on verifying the service's functionality itself, free from the uncertainties of real-world dependencies. This method creates a stable and controlled testing environment, enhancing focus on the specific behaviors and outputs of the service being tested without the distractions posed by real external systems. Conclusion In this article on using Playwright, we come across numerous challenges that should be taken into account during playwright testing. You must pay attention to every step, from including tests in various CI/CD pipelines to ensuring reliable element selectors for successful testing. Maintaining concentrated and separate tests increases reliability, whereas automating and overseeing tests outside of local environments allows you to have ongoing quality assurance. Furthermore, streamlining testing processes can be achieved by avoiding direct testing of third-party integrations and using Playwright's Network API for mocking. By proactively tackling these challenges, you ensure smoother development cycles and stronger, reliable testing results for applications. Related to Integration Testing Frequently Asked Questions 1.

Unleash the power of cloud automation testing! Reduce costs, speed up deployments, and achieve wider test coverage with these actionable tips. 26 June 2024 07 Min. Read Benefits of Cloud Automation Testing WhatsApp LinkedIn X (Twitter) Copy link Checklist for best practices What is Cloud Testing? Cloud testing uses the capabilities of cloud computing to streamline and enhance software testing systems. It is like testing your software on a vast number of devices and environments, all being accessible from the comfort of your desk. Usually software testing involves setting up physical devices and infrastructure which is a resource-intensive and time-consuming endeavour. Cloud testing eliminates this need.
