Considering manual vs. automation testing? Read our blog for a comprehensive comparison and make informed decisions for robust software testing 7 December 2023 12 Min. Read Manual Testing vs Automation Testing : Key Differences WhatsApp LinkedIn X (Twitter) Copy link Get the Comparison Sheet Let’s start this hot discussion by opening with the most debated and burning question, Is manual testing still relevant in the era where AI has taken over, what’s the future of manual testing and the manual testers thereof? What’s the need of manual testing in the era of AI and automation all around? It is an undeniable fact that with the rise in automation and AI, manual testing has definitely taken a back seat. It is all over the internet that manual testing is dying, manual testers are not required anymore. But with what argument? Simply because automation and AI is seeing all the limelight these days, it is not true in all senses that it can completely take over the job of a manual tester or completely eliminate manual testing. Let’s break it down and understand why have this opposing opinion despite of witnessing all the trends: 👉 When a product or software is newly introduced to the market, it's in its early stages of real-world use. At this point, the focus is often on understanding how users interact with the product, identifying unforeseen bugs or issues, and rapidly iterating based on user feedback. Let’s understand this with the help of an example: Consider a new social media app that has just been released. The development team has assumptions about how users will interact with the app, but once it's in the hands of real users, new and unexpected usage patterns emerge. For instance, users might use the chat feature in a way that wasn't anticipated, leading to performance issues or bugs. In this case, manual testers can quickly adapt their testing strategies to explore these unforeseen use-cases. They can simulate the behavior of real users, providing immediate insights into how the app performs under these new conditions. On the other hand, if the team had invested heavily in automation testing from the start, they would need to spend additional time and resources to constantly update their test scripts to cover these new scenarios, which could be a less efficient use of resources at this early stage. 👉 New software features often bring uncertainties that manual testing can effectively address. Manual testers engage in exploratory testing, which is unstructured and innovative, allowing them to mimic real user behaviors that automated tests may miss. This approach is vital in agile environments for quickly iterating new features. Automated testing setup for these features can be resource-intensive, especially when features frequently change in early development stages. However, once a feature is stable after thorough manual testing, transitioning to automated testing is beneficial for long-term reliability and integration with other software components. A 2019 report by the Capgemini Research Institute found that while automation can reduce the cost of testing over time, the initial setup and maintenance could be resource-intensive, especially for new or frequently changing features. Let’s understand this with the help of an example: Consider a software team adding a new payment integration feature to their e-commerce platform. This feature is complex, involving multiple steps and external payment service interactions. Initially, manual testers explore this feature, mimicking various user behaviors and payment scenarios. They quickly identify issues like unexpected timeouts or user interface glitches that weren't anticipated. In this phase, the team can rapidly iterate on the feature based on the manual testing feedback, something that would be slower with automation due to the need for script updates. Once the feature is stable and the user interaction patterns are well understood, it's then automated for regression testing , ensuring that future updates do not break this feature. While automation is integral to modern software testing strategies, the significance of manual testing, particularly for new features and new products, cannot be overstated. Its flexibility, cost-effectiveness, and capacity for immediate feedback make it ideal in the early stages of feature and product development. Now that we’ve established ground on why manual testing is still needed and can never be eliminated from the software testing phase anytime soon, let’s dive deep into the foundational concepts of both the manual and automation testing and understand both of them a little better. Manual Testing vs Automation Testing Manual Testing and Automation Testing are two fundamental approaches in the software testing domain, each with its own set of advantages, challenges, and best use cases. Manual Testing It refers to the process of manually executing test cases without the use of any automated tools. It is a hands-on process where a tester assumes the role of an end-user and tests the software to identify any unexpected behavior or bugs. Manual testing is best suited for exploratory testing, usability testing, and ad-hoc testing where the tester's experience and intuition are critical. Automation Testing It involves using automated tools to execute pre-scripted tests on the software application before it is released into production. This type of testing is used to execute repetitive tasks and regression tests which are time-consuming and difficult to perform manually. Automation testing is ideal for large scale test cases, repetitive tasks, and for testing scenarios that are too tedious for manual testing. A study by the QA Vector Analytics in 2020 suggested that while over 80% of organizations see automation as a key part of their testing strategy, the majority still rely on manual testing for new features to ensure quality before moving to automation. Here is a detailed comparison table highlighting the key differences between Manual Testing vs Automation Testing: Aspect Manual Testing Automation Testing Nature Human-driven, requires physical execution by testers. Tool-driven, tests are executed automatically by software. Initial Cost Lower, as it requires minimal tooling. Higher, due to the cost of automation tools and script development. Execution Speed Slower, as it depends on human speed. Faster, as computers execute tests rapidly. Accuracy Prone to human error. Highly accurate, minimal risk of errors. Complexity of Setup Simple, as it often requires no additional setup. Complex, requires setting up and maintaining test scripts. Flexibility High, easy to adapt to changes and new requirements. Low, requires updates to scripts for changes in the application. Testing Types Best Suited Exploratory, Usability, Ad-Hoc. Regression, Load, Performance. Feedback Qualitative, provides insight into user experience. Quantitative, focuses on specific, measurable outcomes. Scalability Limited scalability due to human resource constraints. Highly scalable, can run multiple tests simultaneously. Suitability for Complex Applications Suitable for applications with frequent changes. More suitable for stable applications with fewer changes. Maintenance Low, requires minimal updates. High, scripts require regular updates. How does Manual Testing work? Manual Testing is a fundamental process in software quality assurance where a tester manually operates a software application to detect any defects or issues that might affect its functionality, usability, or performance. Understanding Requirements : Testers begin by understanding the software requirements, functionalities, and objectives. This involves studying requirement documents, user stories, or design specifications. Developing Test Cases : Based on the requirements, testers write test cases that outline the steps to be taken, input data, and the expected outcomes. These test cases are designed to cover all functionalities of the application. Setting Up Test Environment : Before starting the tests, the required environment is set up. This could include configuring hardware and software, setting up databases, etc. Executing Test Cases : Testers manually execute the test cases. They interact with the software, input data, and observe the outcomes, comparing them with the expected results noted in the test cases. Recording Results : The outcomes of the test cases are recorded. Any discrepancies between the expected and actual results are noted as defects or bugs. Reporting Bugs : Detected bugs are reported in a bug tracking system with details like severity, steps to reproduce, and screenshots if necessary. Retesting and Regression Testing : After the bugs are fixed, testers retest the functionalities to ensure the fixes work as expected. They also perform regression testing to check if the new changes have not adversely affected the existing functionalities. Final Testing and Closure : Once all major bugs are fixed and the software meets the required quality standards, the final round of testing is conducted before the software is released.

We will explore the reasons why the traditional testing pyramid may not work for testing microservices and provide the modified testing pyramid as the ultimate solution. 22 May 2023 07 Min. Read Testing Pyramid: Why won’t it work for microservices testing? WhatsApp LinkedIn X (Twitter) Copy link Get a Demo Microservices architecture has been gaining popularity due to its ability to enhance the agility, scalability, and resiliency of applications. However, testing microservices can be challenging because of their distributed and independent nature. In traditional monolithic applications, the testing pyramid is a widely used framework for testing applications. This framework emphasizes the importance of unit testing, integration testing, and end-to-end testing in ensuring software quality. However, this testing pyramid may not work effectively for testing microservices architecture. In this blog post, we will explore the reasons why the traditional testing pyramid may not work for testing microservices and provide the modified testing pyramid as the ultimate solution. The Traditional Testing Pyramid The traditional testing pyramid is a framework that emphasizes the importance of unit tests, integration tests, and end-to-end tests in ensuring software quality. The pyramid is shaped like a triangle, with unit tests at the bottom, followed by integration tests in the middle, and end-to-end tests at the top. Unit tests are used to test the smallest units of code, typically at the function or class level. Integration tests are used to test how different modules of the application interact with each other. End-to-end tests are used to test the entire application from a user perspective. The traditional " Test Pyramid " suggests balancing unit, integration, and end-to-end tests . This pyramid is designed to provide a framework for testing software applications. However, with the rise of microservices, the traditional testing pyramid has become less useful. Where the Traditional Testing Pyramid Lacks? Microservices architecture is more complex than monolithic architecture. In a microservices architecture, services are distributed and independent, and each service may have its own database, making testing more challenging . This test pyramid approach needs to be modified for testing microservices . E2E tests need to be completely dropped. Aside from being time-consuming to build and maintain, E2E tests execute complete user-flows on the entire application with each test. This requires all services under the hood to be simultaneously brought up (including upstream), even when it is possible to catch the same kind and the same number of failures by testing only a selected group of services; only the ones that have undergone a change. 1. Microservices are highly distributed: Microservices architecture is based on breaking down an application into smaller, independently deployable services that communicate with each other over a network. This distributed nature makes it difficult to test the system as a whole using end-to-end tests. 2. Service boundaries are constantly evolving: Microservices architecture allows for rapid iteration and deployment, which means that the boundaries between services can be constantly changing. This serves as a challenge in maintaining end-to-end tests and integration tests as the system evolves. 3. Testing one service in isolation may not provide enough coverage: Because microservices are highly distributed and rely heavily on communication between services, testing one service in isolation may not be sufficient to ensure the overall quality of the system. 4. Independent Releases: In a microservices architecture, services are independently deployable and release cycles are faster. This makes it challenging to test each service thoroughly before release, and end-to-end testing is more critical than in traditional monolithic applications. The Modified Testing Pyramid for Microservices Microservices have a consumer-provider relationship between them. In a consumer-provider, one microservice (the consumer) relies on another microservice (the provider) to perform a specific task or provide a specific piece of data. The consumer and provider communicate with each other over a network, typically using a well-defined API to exchange information. This means the consumer service could break irreversibly if the downstream service (provider) changes its response that the consumer is dependent on. Since APIs are the key to run microservices-based system, testing them via the contracts they exchange while communicating would be an effective strategy to test them. This approach of selecting and testing only one service at a time is faster, cheaper, and more effective, and can be easily achieved by testing contracts [+data] for each service independently. Test every service independently for contracts [+data], by checking the API response of the service. Service level isolation is the most effective, manageable and scalable strategy for testing a multi-repo system. How HyperTest can help you achieve Contract[+data] testing? HyperTest is a no-code test automation tool for API testing. It is tailor-made to cater the challenges that microservices come with. It helps in running integration tests for all services deployed with HyperTest. If teams find it difficult to build tests that generate response from a service with pre-defined inputs, there is a simple way to test services one at a time using HyperTest Record and Replay mode. HyperTest sits on top of each service and monitors all the incoming traffic for the service under test [SUT]. HyperTest will capture all the incoming requests coming to a particular service and all of its upstream, creating a record for each request. This happens 24x7 and helps HyperTest builds context of the possible API requests or inputs that can be made to the service under test. This recorded traffic is curated into contracts tests by HyperTest. These contracts tests perfectly mimic any actual interaction between the consumer service and the provider service. These contract tests that capture incoming traffic, are then run on the SUT to generate response from 2 branches which are then compared and validated for contracts [+data]. Benefits of Testing Microservices The HyperTest Way Service level contract tests are easy to build and maintain. HyperTest builds or generates these tests in a completely autonomous way. The provider can make changes to their APIs without breaking upstream services. Reduces the need for developers to talk to each other and coordinate, saving time and unnecessary communication. HyperTest localizes the root cause of the breaking change to the right service very quickly, saving debugging time. Very easy to execute, since contract[+data] tests can be triggered from the CI/CD pipelines . Conclusion The traditional testing pyramid is no longer suitable for testing microservices. Microservices architecture requires new testing strategies that can address the challenges that come with this architecture. The contract[+data] is the best alternative testing strategy that can be used to test microservices effectively. This testing strategy focus on testing the API and the interactions between services rather than testing the application as a whole. Adopting this testing strategy will help organizations achieve the scalability, flexibility, and agility that come with microservices architecture. Schedule a demo today to let HyperTest help you in achieving your contract[+data] testing. Related to Integration Testing Frequently Asked Questions 1. What is Testing Pyramid? The Testing Pyramid is a concept in software testing that represents the ideal distribution of different types of tests. It forms a pyramid with a broad base of unit tests (low-level), followed by integration tests (middle-level), and topped by a smaller number of end-to-end tests (high-level). This pyramid emphasizes the importance of testing at lower levels to ensure a stable foundation before conducting higher-level, more complex tests. 2. What kind of tests are performed in the test pyramid? The Testing Pyramid includes Unit Tests, which check individual parts, Integration Tests that validate component interactions, and End-to-End Tests to ensure the entire system works as expected. It emphasizes testing comprehensively while prioritizing efficiency and early issue detection. 3. Does inverting the test pyramid make sense? Inverting the test pyramid, with more end-to-end tests and fewer unit tests, can be justified in some cases based on project needs, but it has trade-offs in terms of speed and maintainability. Adding contract tests and removing or reducing the end-to-end tests can significantly help get the microservices testing right in place.

Example Code Block for Unit Testing with Jest Let's consider a simple React component and a corresponding Jest test: React Component (Button.js): import React from 'react'; function Button({ label }) { return {label}; } export default Button; Jest Test (Button.test.js): import React from 'react'; import { render } from '@testing-library/react'; import Button from './Button'; test('renders the correct label', () => { const { getByText } = render(); const buttonElement = getByText(/Click Me/i); expect(buttonElement).toBeInTheDocument(); }); In this example, we're using Jest along with React Testing Library to test if the Button component correctly renders the label passed to it. Frontend testing is a vast field, and the approach and tools may vary based on the specific requirements of the project. It's crucial to maintain a balance between different types of tests while ensuring the application is thoroughly tested for the best user experience. Diving into Backend Testing In contrast, backend testing targets the server-side of the application. This includes databases, servers, and application logic. Backend testing is essential for validating data processing, security, and performance. It involves tasks like database testing, API testing , and checking the integration of various system components. Types of Backend Testing 1. Unit Testing : Testing individual units or components of the backend code in isolation. Tools : JUnit (Java), NUnit (.NET), PyTest (Python). Example : Testing a function that calculates a user's account balance. 2. Integration Testing : Testing the interaction between different modules or services in the backend. Tools : Postman, SoapUI. Example : Testing how different modules like user authentication and data retrieval work together. 3. Functional Testing : Testing the business requirements of the application. Tools : HP ALM, TestRail. Example : Verifying if a data processing module correctly generates reports. 4. Database Testing: Ensuring the integrity and consistency of database operations, data storage, and retrieval. Tools : SQL Developer, DbUnit. Example : Checking if a query correctly retrieves data from a database table. 5. API Testing : Testing the application programming interfaces (APIs) for functionality, reliability, performance, and security. Tools : Postman, HyperTest, Swagger. Example : Verifying if an API returns the correct data in response to a request. 6. Performance Testing: Evaluating the speed, scalability, and stability of the backend under various conditions. Tools : Apache JMeter, LoadRunner. Example : Assessing the response time of a server under heavy load. 7. Security Testing: Identifying vulnerabilities in the backend and ensuring data protection. Tools : OWASP ZAP, Burp Suite. Example : Testing for SQL injection vulnerabilities. 8. Load Testing: Testing the application's ability to handle expected user traffic. Tools : LoadRunner, Apache JMeter. Example : Simulating multiple users accessing the server simultaneously to test load capacity. Best Practices in Backend Testing Comprehensive Test Coverage : Ensure all aspects of the backend, including databases, APIs, and business logic, are thoroughly tested. Automate Regression Tests : Automate repetitive tests to save time and reduce errors. Realistic Testing Environment : Test in an environment that closely resembles the production setting. Data-Driven Testing : Use varied and extensive datasets to test how the backend handles different data inputs. Prioritize Security : Regularly test for and fix security vulnerabilities. Monitor Performance Regularly : Continuously monitor server performance and optimize when necessary. Version Control for Test Cases : Maintain a version control system for test documentation and scripts. CI/CD Integration : Integrate backend testing into the Continuous Integration/Continuous Deployment pipeline. Test Early and Often : Implement testing early in the development cycle and conduct tests frequently. Collaboration Between Teams : Encourage collaboration between backend developers, testers, and operations teams. HyperTest , our no-code API automation testing tool provides a quick remediation by notifying on disruption. It lets developer of a service know in advance when the contract between his and other services has changed, offering immediate action and better collaboration. Example Code Block for API Testing with Postman Assuming you have an API endpoint /api/users for retrieving user data, you can create a test in Postman: Send a GET request to /api/users. In the "Tests" tab of Postman, write a test script to validate the response: pm.test("Status code is 200", function () { pm.response.to.have.status(200); }); pm.test("Response time is less than 500ms", function () { pm.expect(pm.response.responseTime).to.be.below(500); }); pm.test("Response should be in JSON format", function () { pm.response.to.have.header("Content-Type", "application/json"); }); pm.test("Response contains user data", function () { var jsonData = pm.response.json(); pm.expect(jsonData.users).to.not.be.empty; }); In this example, Postman is used to validate the status code, response time, content type, and data structure of the API response. With all the API collections, API testing becomes all the way tedious and time-consuming with Postman eventually. HyperTest is a way out here, you won’t need to manually write test scripts for all the APIs you have. Here’s a quick overview on Postman Vs HyperTest. Frontend vs. Backend Testing: Key Differences Layer of Testing : Frontend Testing: Focuses on the presentation layer. Backend Testing: Concentrates on the application and database layers. Nature of Testing : Frontend Testing: Involves graphical user interface (GUI) testing, layout, and responsiveness. Backend Testing: Encompasses database integrity, business logic, and server testing.

Read What is Microservices Testing? WhatsApp LinkedIn X (Twitter) Copy link Get a Demo Microservices architecture is a popular design pattern that allows developers to build and deploy complex software systems by breaking them down into smaller, independent components that can be developed, tested, and deployed separately. However, testing a micro-services architecture can be challenging, as it involves testing the interactions between multiple components, as well as the individual components themselves. What is Microservices Architecture? Microservices architecture, characterized by its structure of loosely coupled services, is a popular approach in modern software development, lauded for its flexibility and scalability. The most striking benefits include scalability and flexibility, as microservices allow for the independent scaling of application components. This aspect was notably leveraged by Netflix , which transitioned to microservices to manage its rapidly growing user base and content catalog, resulting in improved performance and faster deployment times. Each service in a microservices architecture can potentially employ a technology stack best suited to its needs, fostering innovation. Amazon is a prime example of this, having adopted microservices to enable the use of diverse technologies across its vast array of services, which has significantly enhanced its agility and innovation capacity. Key Characteristics of Microservices Architecture If you have made the move or thinking of making the move to a multi-repo architecture, consider that done right only if your micro-services fulfil these characteristics i.e. your service should be: 👉 Small: How small is small or micro; if you can do away with the service and rewrite it completely from scratch in 2-3 weeks 👉 Focused on one task : It accomplishes one specific task, and does that well when viewed from the outside 👉 Aligned with bounded context: If a monolith is subdivided into microservices, the division is not arbitrary in fact every service is consistent with the terms and definitions that apply to them 👉 Autonomous : Change the implementation of the service without coordinating with other services 👉 Independently deployable : Teams can deploy changes to their service without feeling the need to coordinate with other teams or services. If you always test your service with others before release, then they are not independently deployable 👉 Loosely coupled : Make external and internal representations different. Assume the interface to your service is a Public API. How Microservices Architecture is Different from Monolithic Architecture? People hardly are sticking to the conventional architectural approach, i.e., the monolithic approach these days . Considering the benefits and agility microservices bring to the table, it’s hard for any company to be left behind in such competitive space. However, we have presented the differences in a tabular form, click here to learn about the companies that switched from monoliths to microservices. Testing Pyramid and Microservices The testing pyramid is a concept used to describe the strategy for automated software testing. It's particularly relevant in the context of microservices due to the complex nature of these architectures. It provides a structured approach to ensure that individual services and the entire system function as intended. Given the decentralized and dynamic nature of microservices, the emphasis on automated and comprehensive testing at all levels - unit, integration, and end-to-end - is more critical than ever. The Layers of the Testing Pyramid in Microservices a. Unit Testing (Bottom Layer): In microservices, unit testing involves testing the smallest parts of an application independently, such as functions or methods. It ensures that each component of a microservice functions correctly in isolation, which is crucial in a distributed system where each service must reliably perform its specific tasks. Developers write these tests during the coding phase, using mock objects to simulate interactions with other components. b. Integration Testing (Middle Layer): This layer tests the interaction between different components within a microservice and between different microservices. Since microservices often rely on APIs for communication, integration testing is vital to ensure that services interact seamlessly and data flows correctly across system boundaries. Tests can include API contract testing, database integration testing, and testing of client-service interactions. c. End-to-End Testing (Top Layer): This involves testing the entire application from start to finish, ensuring that the whole system meets the business requirements. It’s crucial for verifying the system's overall behavior, especially in complex microservices architectures where multiple services must work together harmoniously. Automated end-to-end tests simulate real user scenarios and are typically run in an environment that mimics production. The Problem with Testing Pyramid The testing pyramid provides a foundational structure, but its application in microservices requires adjustments. Since the distributed and independently deployable nature of this multi-repo systems presents challenges while adopting the testing pyramid. 👉The Problem with End to End tests Extremely difficult to write, maintain and update: An E2E test that actually invokes the inter service communication like a real user would catch this issue. But cost of catching this issue with a test that could involve many services would be very high, given the time and effort spent creating it. The inter-service communication in microservices architectures introduces complexity, making it difficult to trace issues. Ensuring that test data is consistent across different services and test stages. 👉The Problem with Unit tests The issue of mocks: Mocks are not trustworthy, specially those that devs write themselves. Static mocks that are not updated to account for changing responses could still miss the error. Replicating the production environment for testing can be challenging due to the distributed nature of microservices. For microservices, the interdependencies between services mean integration testing becomes significantly more critical. Ensuring that independently developed services interact correctly requires a proportionally larger emphasis on integration testing than what the traditional pyramid suggests. So a balanced approach with a stronger emphasis on integration and contract testing, while streamlining unit and end-to-end testing, is essential to address the specific needs of microservices architectures. Why Testing Microservices is a Challenge? This bring us to the main topic of our article, why testing microservices is a challenge in itself. We have now understood where the testing pyramid approach lacks and how it needs some adjustments to fit into the microservices system. Testing multi-repo system need a completely different mindset and strategy. This testing strategy should align with the philosophy of running a multi-repo system i.e. test services at the same pace at which are they are developed or updated. Multi-repo systems have a complex web of interconnected communications between various micro-services. Complex Service Interactions : Microservices operate in a distributed environment where services communicate over the network. Testing these interactions is challenging because it requires a comprehensive understanding of the service dependencies and communication protocols. Ensuring that each service correctly interprets and responds to requests from other services is critical for system reliability. Diverse Technology Stacks : Microservices often use different technology stacks, which can include various programming languages, databases, and third-party services. This diversity makes it difficult to establish a standardized testing approach. Isolation vs. Integration Testing : Balancing between isolated service tests (testing a service in a vacuum) and integration tests (testing the interactions between services) is a key challenge. Isolation testing doesn’t capture the complexities of real-world interactions, while integration testing can be complex and time-consuming to set up and maintain. Dynamic and Scalable Environments : Microservices are designed to be scalable and are often deployed in dynamic environments like Kubernetes. This means that the number of instances of a service can change rapidly, complicating the testing process. Data Consistency and State Management : Each microservice may manage its own data, leading to challenges in maintaining data consistency and state across the system. Testing must account for various data states and ensure that transactions are handled correctly, especially in distributed scenarios where services might fail or become temporarily unavailable. Configuration and Environment Management : Microservices often rely on external configuration and environment variables. Testing must ensure that services behave correctly across different environments (development, staging, production) and that configuration changes do not lead to unexpected behaviors. The Right Approach To Test Microservices We are now presenting an approach that is tailor-made to fit your microservices architecture. As we’ve discussed above, a strategy that tests integrations and the contracts between the services is an ideal solution to testing microservices. Let’s take an example to understand better: Let's consider a simplified scenario involving an application with two interconnected services: a Billing service and a User service. The Billing service is responsible for creating invoices for payments and, to do so, it regularly requests user details from the User service. Here's how the interaction works: When the Billing service needs to generate an invoice, it sends a request to the User service. The User service then executes a method called and sends back all the necessary user details to the Billing service. Imagine a situation where the User service makes a seemingly minor change, such as renaming an identifier from User to Users . While this change appears small, it can have significant consequences. Since the Billing service expects the identifier to be User , this alteration disrupts the established data exchange pattern. The Billing service, not recognizing the new identifier Users , can no longer process the response correctly. This issue exemplifies a " breaking change " in the API contract. The API contract is the set of rules and expectations about the data shared between services. Any modification in this contract by the provider service (in this case, the User service) can adversely affect the dependent service (here, the Billing service). In the worst-case scenario, if the Billing service is deployed in a live production environment without being adapted to handle the new response format from the User service, it could fail entirely. This failure would not only disrupt the service but also potentially cause a negative user experience, as the Billing service could crash or malfunction while users are interacting with it. Testing Microservices the HyperTest Way Integration tests that tests contracts [+data]: ✅Testing Each Service Individually for Contracts: In our example the consumer service can be saved from failure using simple contracts tests that mock all dependencies like downstreams and db for the consumer. Verifying (testing) integrations between consumer and provider by mocking each other i.e. mocking the response of the provider when testing the consumer, and similarly when testing the provider mocking of the outgoing requests from the consumer. But changing request / response schema makes the mocks of either of the services update real-time, making their contract tests valid and reliable for every run. This service level isolation helps test every service without needing others up and running at the same time. Service level contract tests are much simple to maintain than E2E and unit tests, but test maintenance is still there and this approach is not completely without effort. ✅Build Integration Tests for Every Service using Network Traffic If teams find it difficult to build tests that generate response from a service with pre-defined inputs, there is a simple way to test services one at a time using HyperTest Record and Replay mode. We at HyperTest have developed just this and this approach will change the way you test your microservices, reducing all the efforts and testing time you spend on ideating and writing tests for your services, only to see them fail in production. If teams want to test integration between services, HyperTest sits on top of each service and monitors all the incoming traffic for the service under test [SUT]. Like in our example, HyperTest will capture all the incoming requests, responses and downstream data for the service under test (SUT). This is Record mode of HyperTest. This happens 24x7 and helps HyperTest builds context of the possible API requests or inputs that can be made to the service under test i.e. user service. HyperTest then tests the SUT by replaying all the requests it captured using its CLI in the Test Mode. These requests that are replayed have their downstream and database calls mocked (captured during the record mode). The response so generated for the SUT (X'') is then compared with the response captured in the Record Mode (X'). Once these responses are compared, any deviation is reported as regression. A HyperTest SDK sitting on the down stream updates the mocks of the SUT, with its changing response eliminating the problem of static mocks that misses failures. HyperTest updates all mocks for the SUT regularly by monitoring the changing response of the down streams / dependent services Advantages of Testing Microservices this way Automated Service-Level Test Creation : Service level tests are easy to build and maintain. HyperTest builds or generates these tests in a completely automatically using application traffic. Dynamic Response Adaptation : Any change in the response of the provider service updates the mocks of the consumer keeping its tests reliable and functional all the time. Confidence in Production Deployment : With HyperTest, developers gain the assurance that their service will function as expected in the production environment. This confidence comes from the comprehensive and automated testing that HyperTest provides, significantly reducing the risk of failures post-deployment. True Shift-Left Testing : HyperTest embodies the principle of shift-left testing by building integration tests directly from network data. It further reinforces this approach by automatically testing new builds with every merge request, ensuring that any issues are detected and addressed early in the development process. Ease of Execution : Executing these tests is straightforward. The contract tests, inclusive of data, can be seamlessly integrated and triggered within the CI/CD pipeline, streamlining the testing process. HyperTest has already been instrumental in enhancing the testing processes for companies like Nykaa, Shiprocket, Porter, and Urban Company, proving its efficacy in diverse environments.

Explore software testing—its importance, test types, and best practices in automation for effective testing. 4 December 2023 11 Min. Read What is Software Testing? A Complete Guide WhatsApp LinkedIn X (Twitter) Copy link Get 101 Guide From every food order that you place to all the alarms that you snooze every morning, it’s all software. Today’s world is driven by software and the APIs that are making all the connectivity possible between humans and the software. In a world increasingly reliant on technology, the importance of robust and effective software testing cannot be overstated. Whether it's a mobile app, a web platform, or an enterprise system, software testing helps identify and fix bugs, improves performance, and ensures that the software meets the intended requirements and user expectations. What is Software Testing? Software testing is a critical process in the development of software applications. Its primary goal is to ensure that the software meets its specified requirements and to identify any defects or issues before the software is released to users. It is the process of evaluating and verifying that a software application or system meets specified requirements and works as expected. It involves executing software components using manual or automated tools to detect errors, bugs, or any other issues. This is not just about finding faults in the software but also about enhancing its quality and usability. Why Software Testing is important? Software testing is an integral part of software development, playing a key role in delivering a high-quality, reliable, and secure product. It not only benefits the users but also the developers and the company as a whole, making it an indispensable process in the software development lifecycle. 👉Ensuring Quality and Reliability The primary goal of software testing is to ensure that the application works as intended. By identifying bugs and issues before the software reaches the end user, testers can prevent potential failures that could be costly or damaging. This process helps in maintaining a high standard of quality, ensuring that the software performs reliably under various conditions. 👉User Satisfaction and Trust Software that has undergone thorough testing provides a better UX. Users are less likely to encounter bugs or crashes, leading to higher satisfaction and trust in the product. This, in turn, can lead to increased user retention, positive reviews, and recommendations, which are vital for the success of any software. 👉Cost-Effective Development Detecting issues early in the development process can significantly reduce the cost of fixing them. If bugs are found after the software has been released, the cost of rectification can be much higher, both in terms of financial resources and time spent. Effective testing during the development stages helps in reducing these post-release costs. 👉Security With the increasing threat of cyber-attacks, security has become a paramount concern in software development. Testing helps to identify vulnerabilities and security flaws that could be exploited by attackers, thereby protecting sensitive data and maintaining the integrity of the software. Need of Software Testing Let's delve into a recent software failure that gained prominence, causing significant financial losses and tarnishing the reputation of this well-established airlines. Case Study: Southwest Airlines Software Failure Introduction The Southwest Airlines software failure is a prime example of how inadequate technological infrastructure and lack of timely investment in software updates can lead to catastrophic operational disruptions. Background Southwest Airlines, renowned for its extensive domestic network, faced an unprecedented operational crisis during a busy holiday travel season. This period coincided with challenging weather conditions across the United States. The Incident As severe weather hit, most airlines navigated through the complications, but Southwest Airlines experienced a near-total operational shutdown. The crux of the problem was not flight cancellations due to weather alone, but primarily a failure in the airline’s software system, which was responsible for managing flight operations, including crew scheduling. Analysis of Causes Outdated Software System : The software used by Southwest was reportedly outdated and not adequately equipped to handle the high volume of operational changes required during the severe weather conditions. Lack of Investment : Prior to the incident, there had been a lack of investment in updating the software system. This inaction led to accumulated 'technical debt', where temporary solutions and postponements in essential upgrades compounded the system's inefficiencies. Operational Overload : The combination of high travel demand, severe weather, and an inflexible software system led to a cascade of scheduling conflicts and operational disruptions. Impact Financial Losses : Southwest Airlines faced an estimated loss of around $1 billion due to this operational paralysis. Reputation Damage : The incident severely impacted the airline's reputation, especially regarding reliability and operational efficiency. Customer Dissatisfaction : Thousands of passengers were stranded or faced significant delays, leading to widespread customer dissatisfaction and eroding a previously loyal customer base. Now let’s understand how adequate software testing practices could have mitigated this failure: In this case, the lack of adequate software testing played a pivotal role in the failure. Software testing is essential for identifying potential weaknesses and issues in a system before they become critical problems. In Southwest's situation, thorough testing could have revealed the software's inability to handle high-stress scenarios, like those presented by severe weather conditions combined with high travel demand. Adequate software testing practices involve several key components: Regular and Comprehensive Testing : Continuous testing of software systems, especially before peak operational periods, is crucial. This would have allowed Southwest to identify and address any limitations in their system's capacity to handle sudden changes in flight schedules and crew assignments. Stress Testing : This involves testing the software under extreme conditions to ensure it can handle unexpected surges in demand or other challenging scenarios. Had Southwest conducted rigorous stress testing, the software's inadequacies in handling the holiday rush and weather disruptions might have been identified and mitigated in advance. Investment in Testing Resources : Allocating sufficient resources, both in terms of budget and expert personnel, for software testing is vital. It appears that Southwest may have overlooked this aspect, leading to an outdated and untested system. Feedback Loops and Continuous Improvement : Effective software testing is not a one-time event but a continuous process. Feedback from each testing phase should be used to improve and update the software regularly. Had Southwest Airlines implemented robust software testing practices, the likelihood of such a failure could have been significantly reduced. Regular updates and improvements, guided by comprehensive testing results, would have ensured that the software remained capable of handling the dynamic and demanding nature of airline operations. Approaches to Perform Software Testing 1. Black Box Testing: The Mystery Box Approach Imagine a mystery box where you can't see what's inside. Black Box testing is like this; testers evaluate the software based only on its outputs, without knowing the internal code structure. Key Characteristics: Focus : It focuses on the functionality of the software. Method : Test cases are designed based on specifications and requirements, not code. Who Performs It : Typically done by testers who don’t have knowledge of the underlying code. Example : Testing a calculator application by checking if the addition function returns the correct result for given inputs, without knowing how the function is implemented in code. 2. White Box Testing: The Transparent Machine White Box testing is like looking inside a transparent machine. Testers can see the inner workings and understand how it operates. Key Characteristics: Focus : It involves looking at the structure and logic of the code. Method : Testers write test cases that cover code paths, branches, loops, and statements. Who Performs It : Usually performed by developers who have an understanding of the code. Example : Testing a function in a software by writing test cases that cover all the possible paths in the code, including all the conditions and loops. 3. Grey Box Testing: The Semi-Transparent Approach Grey Box testing is akin to looking at a machine with some transparent parts and some opaque. It’s a blend of both Black Box and White Box testing methods. Key Characteristics: Focus : Testers have partial knowledge of the internal workings of the application. Method : Combines the high-level perspective of Black Box testing with some level of internal code awareness. Who Performs It : Often done by testers who have a good understanding of both the domain and the technical aspects. Example : Testing a web application by considering both the user interface and underlying code, such as checking whether user inputs are properly validated before being processed by the system. Each of these testing approaches provides a different lens through which to examine software, offering a comprehensive understanding of its quality, performance, and security. In practice, a balanced combination of these methods is often the most effective strategy in software testing. Types of Software Testing The following are the major types of software testing methodologies: Unit testing : The most basic of them all, they’re the first tests to be performed. Mostly written by devs, they test a particular unit or block of code before it gets tested in integration. Tools like JUnit, NUnit are used to perform unit testing . Integration testing : The second layer of testing, they tests different parts of an application together or when they’re integrated. This helps in reflecting out bugs that arise when different units interact. This is the most useful type of testing and tools like HyperTest, Citrus, etc can be used to effectively test your system interactions. End-to-end test: These tests are performed to check the complete system at once, making them lengthy and time-consuming. Though they check the whole system, from the UI to the backend part, they often miss to locate the root cause of failure. Tools like Selenium, LambdaTest are used for this. Functional Testing : This focuses on testing the software against its functional requirements. An example would be checking if a login feature works as intended, accepting valid credentials and rejecting invalid ones. Non-Functional Testing : It tests aspects not related to specific behaviors or functions, such as performance, scalability, and usability. Testing how many users an application can handle simultaneously (load testing) falls under this category. Regression Testing : This ensures that new code changes don’t adversely affect existing functionalities. An example is retesting a previously functioning feature after updates to ensure it still works correctly. Acceptance Testing : This determines if the software is ready for release, typically done by the end-users. Mainly evaluating the complete system against the pre-requisite checklist. For instance, a beta test of a new video game by select users before public release. Smoke Testing : Often known as "build verification testing," this is a preliminary test to check the basic functionality of the software. The Software Testing Lifecycle The Software Testing Lifecycle (STLC) involves a series of distinct activities executed during the testing phase, each with its own importance: Analyzing Requirements : This step involves understanding and specifying the aspects of the software that need to be tested. Planning for Testing : Here, the strategy for testing is developed, along with the determination of necessary resources. Developing Test Cases : This phase focuses on creating comprehensive test scenarios to cover all testing requirements. Setting Up the Test Environment : Preparing the appropriate environment for conducting the tests. Executing the Tests : In this stage, the prepared test cases are run and the outcomes are recorded. Logging Defects : Any faults or issues discovered during the testing are documented in this phase. Concluding the Tests : Finally, the testing process is summarized, reviewing the results and drawing conclusions about the software's quality. Best Practices for Software Testing Software testing should be performed diligently to keep the software updated, secure and to make sure it works as intended. Here are some key practices to follow to follow software testing: Understand Requirements Clearly : Before beginning testing, it's crucial to have a thorough understanding of the software requirements. This ensures that the tests cover all aspects of the specifications and the software is built as per user needs. Plan Testing Activities : Effective testing requires careful planning. This includes defining the scope of testing, selecting appropriate testing methods, allocating resources, and scheduling testing activities. Prioritize Test Cases : Not all test cases are equally important. Prioritize them based on the impact, frequency of use, and criticality of the software features. Focus on high-risk areas first. Automate Where Possible : Automate repetitive and regression tests to save time and resources. However, remember that not everything can be automated, and manual testing is still important for exploratory, usability, and ad-hoc testing scenarios. Adopt Different Testing Types : Employ various types of testing like unit testing, integration testing, system testing, and acceptance testing. Each of these tests offers unique value and helps in identifying different kinds of issues. Adopt a shift-left approach : Start testing as soon as possible in the software development lifecycle. Early testing helps in identifying and fixing defects early, which can save costs and time. Encourage Bug Reporting Culture : Foster an environment where finding and reporting bugs is encouraged. This helps in improving the quality of the software. Perform Regression Testing : After each change or fix, conduct regression testing to ensure that the new code changes have not adversely affected existing functionalities. Ensure Test Environment Mimics Production : The test environment should closely resemble the production environment. This helps in identifying environment-specific issues and reduces the risk of unexpected behaviors after deployment. Consider User Perspective : Always consider the end user's perspective while testing. This helps in ensuring the usability and user-friendliness of the software. Challenges in Software Testing Keeping up with rapidly changing technologies and methodologies. Balancing between thorough testing and meeting tight deadlines. Ensuring testing covers all possible scenarios, including edge cases. Navigating complex integrations and compatibility issues. Deciding which test cases to automate for efficiency. Ensuring software security and performance in diverse scenarios.

Read Software Regression Testing-Build Regression Suite Guide Free WhatsApp LinkedIn X (Twitter) Copy link Get Best Automation Tool In a discussion on API changes, Dennis explains how dependencies between services can increase complexity and lead to breakdowns if not managed properly. Organizations must either eliminate or manage these dependencies to avoid disruptions during system updates. - Dennis Stevens from LeadingAgile When we modify any part of how one service talks to other services, it tends to introduce a breaking change in the system if all the other dependent services are not updated. This is a serious problem devs and EMs are looking to solve. Since in the race to put the best version of their application to end-users, engineers are actively making changes to the apps–introducing new features, modifying based on user’s feedback etc. Some teams are deploying changes on a day-to-day basis, i.e the Kanban way Others are also following a sprint of 15 days or 1 month, but all are in the same race to be agile without breaking things However, at this pace, issues are inevitable, and the code sometimes " turns red ." Even if you test and then release the newly developed code, the integration of the new feature with other dependencies often remains untested or passed on to the next sprint for testing. But it is already broken by then–and the same cycle gets repeated. Let's ship it now and fix it later. To solve this problem, you need an approach that can: Automatically generate integration tests from the application traffic, so that devs don’t have to write/maintain these tests. More importantly, these tests automatically update themselves as you push new changes to your application, hence catching all the regressions at the point of origin only. Fast-moving teams like PayU, Skaud, Fyers, Yellow.ai etc are already taking advantage of this approach and thus are one-step ahead in their development cycle. See if this approach can also help you in keeping your backend sane and tested. Get your free guide to build a regression test suite Introducing changes to a large and cohesive code base can be challenging. When you add new features, fix bugs, or make enhancements, it might affect how the current version of your app, web application, or website functions. Although automated tests like unit tests can help, this guide on regression testing offers a more thorough approach to managing these changes. It will walk you through how to ensure that new updates don’t disrupt your existing functionalities, giving you a reliable method to build a regression suite. What is Regression Testing? Regression testing is very simple to understand. It is all about making sure that everything still works as it should when you introduce new features to your software. When you add new code, it can sometimes clash with existing code. This might lead to unexpected issues or bugs in the software applications. Catch all the regressions/changes as and when any of your service undergoes modification. Ask us how? You might need to carry out regression testing after several types of changes, such as: Bug fixes Software enhancements Configuration adjustments Even when replacing hardware components Regression testing essentially asks, “Does everything still work as expected?” If a new release causes a problem in another part of your system, it’s called a “regression,” which is why we call it “regression testing.” This process helps you catch and fix those issues, keeping your software running smoothly. Why Regression Testing? Regression testing is crucial for your development process because it: Detects Issues : It helps you spot any defects or bugs introduced by recent changes, making sure that updates don’t mess up existing features or new code. Ensures Stability : It confirms that your current features stay functional and stable after modifications, preventing unexpected behavior that could disrupt your users. Mitigates Risks : It helps in identifying and addressing potential risks from changes, avoiding system failures or performance problems that could affect your business operations. Prevents Domino Effect : By catching issues early from minor code changes, regression testing helps you avoid extensive fixes and keeps your core functionalities intact. Supports Agile : It fits well with Agile practices by allowing for continuous testing and frequent feedback, so you don't end up with a buildup of broken code before releases. Enhances Coverage : Regular regression tests boost your overall test coverage, helping you maintain high software quality over time. Testing APIs with all possible schema and data is the quickest way to test every scenario and cover application code quickly like functions, branches and statements. API tests written right can truly test the intersection between different components of an application quickly, reliably and consistently. HyperTest builds API tests that cover every scenario in any application including all edge cases. It provides a code coverage report to highlight the covered code paths to confirm if all possible functional flows are covered . Example of Regression Testing Catching Regressions in a Banking Application: A Real Case Study Challenge : When new features were added to the online banking app, there was a risk that they might disrupt existing functionalities. Approach : We set-up HyperTest SDK on each of the service and rest everything it can take care of. HyperTest automatically started generating integration tests from the application traffic. It found some regression in its replay/ test mode, basically deviation/change from the baseline response that it recorded during the record mode. It reports that change as a regression and now it's up to you to roll back to the previous version or to update all the dependent services. In this banking app example: our oldBalance was 1000. after addition of 500, the newBalance should come as 10500. but due to some modification in this service, now the newBalance is coming as 9500. Results: The expected response is the baseline response against which the new/ real response is compared to and regressions like this are reported. So instead of addition, the updated logic is doing subtraction, which is something to be corrected immediately considering how crucial the operations are in fintech app. Set up HyperTest for your app and never miss to catch any regressions. Regression Testing Techniques When you are adding regression testing to a mature project, you don’t have to test everything from the beginning. Here are some techniques you can use: Unit Regression Testing: Start with a broad overview of your code changes. This approach is great for kicking off regression testing in your existing project and involves testing specific items from your list. Partial Regression Testing: This technique divides your project into logical units and focuses on the most critical parts. You have to create specific test cases for these areas while applying unit regression testing to the other modules. Complete Regression Testing: This is the most detailed approach. It involves a thorough review of your entire codebase to test all functionalities that could affect usability. While it’s comprehensive, it’s also time-consuming and is best suited for earlier stages of your project. By choosing the right technique, you can effectively manage your regression testing and ensure that your project remains stable and reliable. Now, let us see how to execute regression testing. Process of Regression Testing When you are performing regression testing, here’s a step-by-step guide to follow: Change Implementation : Start by modifying your source code to add new features or optimize existing functionality. Initial Failure: Run your program and check for any failures in the test cases that were previously designed. These failures will likely be due to the recent code changes. Debugging : Identify the bugs in your modified source code and work on debugging them. Code Modification: Make the necessary changes to fix the bugs you’ve identified. Test Case Selection : Pick the relevant test cases from your existing suite that cover the modified and affected areas of your code. If needed, add new test cases to ensure comprehensive coverage. Regression Testing: Ultimately, you must perform regression tests with the chosen test cases to verify that your modifications do not cause fresh problems. By adhering to these procedures, you can guarantee that your software's performance is not harmed by your updates. However, it is important to build a regression test suite that includes different test cases for a specific type of feature of software applications. Such a regression test suite is executed automatically whenever a code change is made. Let us understand this in detail. Best Practices for Your Regression Test Suites When it comes to developing, executing, and maintaining your regression test suites, here are five best practices to keep in mind: Think about the specific purpose of your regression test suite. Design it with that goal in mind and manage its scope to ensure it stays focused. Choose your test cases based on factors like code complexity, areas where defects tend to cluster, and the priority of features. This way, you’re targeting the most important areas. Make sure the test cases you select are risk-based, giving you the right coverage for potential issues. This helps you catch problems before they affect your users. Your regression test suite should not be static. Regularly optimize it to adapt to changes in your application and ensure it remains effective. For the test suites you use frequently, consider automating them. This can save you time and effort, allowing you to focus on more complex testing tasks. Conclusion Effective software regression testing is crucial for keeping your application running smoothly and performing well. By following best practices to create and manage a regression test suite, your team can make sure that updates do not introduce new bugs. This ultimately leads to happier users and more reliable operations. This guide is here to help you set up a strong regression testing process.

Get Your Test Automation Suite Up and Running in a Day, Ditch the Manual Efforts Required. 07 Min. Read 14 August 2024 5 Steps To Build Your API Test Automation Vaishali Rastogi WhatsApp LinkedIn X (Twitter) Copy link Writing and maintaining test cases with Postman was all fun, until there was no agile development. Taking all the time to create collections, fire API calls, test APIs and then maintain all that was a thing of past. Now that the time demands the engineering teams to build fast and release faster, Postman and such tools can’t be of much help. HyperTest, our autonomous integration testing tool, can take away all the manual efforts required in Postman. Developers of companies like Skaud, Yellow.ai , Porter, Purplle, Zoop etc are already ahead of their deadlines and are able to focus on making the application better instead of being trapped in the never-ending cycle of writing and maintaining test cases. HyperTest has significantly reduced my test maintenance workload. No more juggling countless test cases or manually tracking API responses on Postman. It's a game-changer! Pratik Kumar, FLEEK TECHNOLOGIES Here’s an easy 5 step guide to build a robust API test automation suite: 1️⃣ Pick any service and install HyperTest SDK 2️⃣ Deploy your service normally either locally or any other environment. HyperTest will record all the incoming and outgoing traffic of that service in that environment. 3️⃣ Go to HyperTest dashboard of all incoming and outgoing calls of this service put together as end-to-end inetgration tests 4️⃣ Install HyperTest CLI. Run these tests on a new build of your service. It will catch regressions across your service response and outgoing calls. 5️⃣ You can make HyperTest tests part of your CI pipeline using pre-push commit hooks and sign-off every release using these autonomous test suites. 1. Installing HyperTest SDK To begin, you'll need to install the HyperTest SDK and its CLI tool. These are the core components that enable HyperTest to interact with your application and manage API test automation effectively. The installation process is straightforward and can be done using package managers like npm for Node.js applications. Once installed , you need to initialize the HyperTest SDK in your application, which typically involves adding a simple configuration file or command to integrate HyperTest with your app's codebase. 💡 Get started with HyperTest within 10 minutes of installation and start catching regressions from the very start. 2. Start your Application in Record Mode After setting up the SDK, you'll need to start your application in "record mode." This mode enables HyperTest to monitor and capture all the outbound API calls your application makes. When your application runs in this mode, HyperTest listens to the requests and the corresponding responses, creating a record of interactions with external services. This recording forms the basis for generating mock data that will be used during regression testing. 3. Introduce Live Traffic in Your Application To ensure HyperTest can capture a wide range of scenarios, introduce some live traffic to your application. This can be done by simulating user activity or running existing test scripts that make API calls. The HyperTest SDK will record the requests made to downstream services, along with their responses. These recordings are crucial for creating accurate mocks that simulate real-world conditions during regression testing. 💡 Invest in 100% automation and let your developers focus on speedy releases while ensuring quality code. 4. Use HyperTest CLI to run the Test Mode Once the recording phase is complete, you can use the HyperTest CLI to replay the recorded requests. During this phase, the actual API calls will be replaced with the previously recorded mock responses. This allows you to test your application in a controlled environment, ensuring that any changes in your code do not break existing functionality. After running these tests, HyperTest generates a regression report that highlights any discrepancies or issues detected. 5. Use the Dashboard to View All the Regressions The final step is to access the HyperTest Dashboard, where you can view the detailed regression/coverage report. It provides a comprehensive evaluation of your test results, including pass/fail statuses, differences between expected and actual responses, and more. This visualization helps you quickly identify and address any regressions introduced during development, ensuring your application remains stable and reliable.
