Unsure if your software is working correctly? Learn the differences between sanity testing and smoke testing to ensure your application functions as expected. 18 June 2024 09 Min. Read Sanity Testing Vs. Smoke Testing: What Are The Differences? WhatsApp LinkedIn X (Twitter) Copy link Checklist for best practices What is Smoke Testing? Smoke testing is a preliminary set of tests conducted on a new software build to verify its basic functions and stability . 💡 It is more like buying a new electronic appliance. Before plugging it in, you are likely to perform a basic check — is it plugged in properly? Does the power light turn on? Smoke testing is a lightweight software process that is undertaken by both testers and developers with the goal being the identification of any major showstopper bugs that would prevent further testing from proceeding effectively. It is a health check for the software build — if the software fails these basic tests, it is typically considered ‘’ unsmokable ’’ and returned to developers for bug fixes before proceeding with more in-depth testing. Smoke testing, thus, serves as a critical first line of defense, ensuring only stable builds progress to further testing stages. Here's what smoke testing typically involves: Core Functionality Checks: Can users log in successfully? Do basic actions like data entry and navigation work as expected? These basic verification checks ensure the software is in a minimally functional state before dedicating time and resources to further testing. Integration Checks: In applications with multiple components, smoke testing might involve verifying basic communication and data exchange between these components. This ensures a foundational level of integration before moving on to more complex testing scenarios. Regression Checks (Basic): While not a substitute for comprehensive regression testing , smoke testing might include some basic checks to identify any regressions (reintroduced bugs) from recent code changes. This helps catch critical regressions early on, preventing wasted effort on testing a potentially broken build. What is Sanity Testing? Sanity testing focuses on a specific set of checks designed to verify core functionalities and basic user flows, unlike comprehensive testing procedures. It is a quick health check for your software after code changes. Sanity testing is essentially a gatekeeper that ensures the build is stable for further, more rigorous testing. Sanity testing prioritizes speed and efficiency, allowing testers to assess the build’s stability and identify critical problems early on. Here's what sanity testing typically involves: Verifying Key Functionalities: The core functionalities that keep the software running smoothly are the primary focus. This involves testing logins, data entry and basic navigation to ensure these essential functions have not been broken by recent code changes. Quick Smoke Test Integration: Sanity testing incorporates basic smoke test elements, focusing on verifying the most fundamental functionalities of the software to identify any major showstopper bugs. Regression Checks (Limited): While not a replacement for comprehensive regression testing , sanity testing might include limited checks to ensure critical functionalities have not regressed (introduced new bugs) due to recent changes. Sanity Testing vs. Smoke Testing: Core Differences Both smoke testing and sanity testing act as initial quality checks for new software builds. However, they differ in their scope, goals and execution. Here's a breakdown of sanity testing vs. smoke testing: Focus: Smoke Testing: The focus is on verifying the absolute basics — Can users log in? Do core functionalities like data entry and saving work as expected? The goal is to identify any major roadblocks that would prevent further testing altogether. Sanity Testing: Sanity testing delves a bit deeper while still prioritising core functionalities. Its aim is to ensure not only basic functionality but also the stability of key user flows and core features after code changes. It is a more in-depth health check compared to the basic smoke test. Scope: Smoke Testing: Smoke testing has a narrower scope. It typically involves a small set of pre-defined tests designed to catch showstopper bugs. The idea is to quickly identify major issues before investing time and resources in further testing. Sanity Testing: Sanity testing has a slightly broader scope than smoke testing. It involves additional checks beyond the core functionalities, ensuring basic user journeys and interactions function as intended. This provides a more complete picture of the build's stability. Execution: Smoke Testing: Smoke testing is designed for speed and efficiency. It involves testers or developers running a pre-defined set of automated tests to quickly assess the build's basic functionality. Sanity Testing: Sanity testing is more flexible in its execution. While some level of automation might be employed, testers often design test cases based on their knowledge of the recent code changes and the application's core functionalities. Smoke testing acts as the initial hurdle, ensuring the build is minimally functional before further testing commences. Sanity testing builds upon this foundation by providing a more in-depth check of core functionalities and user flows. Development teams can use both techniques for a more efficient and effective testing strategy, ultimately leading to the delivery of high-quality software by understanding the core differences in sanity testing vs. smoke testing. Feature Smoke Testing Sanity Testing Purpose Identify critical issues preventing basic functionality Validate new features/bug fixes and their impact Goal Ensure minimal viability for further testing Determine stability for in-depth testing Focus Core functionalities across the entire application Specific functionalities or features impacted by recent changes Depth Shallow check Dives deeper into targeted areas Scope Broad Narrow Timing Performed first on initial builds Performed after some build stability Documentation Often documented or scripted Usually not documented or scripted Execution Can be automated or manual Typically manual Analogy Smoke check to see if the engine starts Targeted inspection of new parts before a full drive Smoke and Sanity Testing Both smoke and sanity testing play important roles in software development, but their applications to specific things differ. Here's a closer look at examples illustrating the key distinctions between them: 1. Smoke Testing Example: Imagine a new build for a social media application is released. Here's how smoke testing might be implemented: Test Case 1: User Login: The smoke test would verify if users can log in successfully using their existing credentials. A failed login could indicate issues with user authentication or database connectivity, thus preventing further testing. Test Case 2: Creating a New Post: The main function of the application is creating new posts. The smoke test would check if users can successfully create a new post with text and an image. Failure here could signify problems with data entry, content storage or image upload functionality which ultimately requires further investigation before proceeding. Test Case 3: Basic Navigation: Smoke testing would involve verifying if users can navigate through the main sections of the application, such as the home feed, profile page and messaging section. Inability to navigate smoothly could indicate issues with the user interface or underlying routing mechanisms. These smoke tests are designed to be quick and automated whenever possible. If any of these basic functionalities fail, the build would be considered " unsmokable " and returned to developers for bug fixing before further testing commences. 2. Sanity Testing Example: Let's consider the same social media application after a code change that has focused on improving the newsfeed algorithm. Here's how sanity testing might be applied: Test Case 1: Login and Feed Display: Sanity testing would include a basic login check, similar to smoke testing. Then, it would verify if the user's newsfeed displays content after logging in, thus ensuring core functionality is not broken. Test Case 2: Newsfeed Content Relevance: Since the code change focused on the newsfeed algorithm, sanity testing would delve deeper. It usually would involve checking if the content displayed in the newsfeed is somewhat relevant to the user's interests or past interactions (a basic test of the new algorithm). This ensures the main functionality of the newsfeed has not been entirely broken by the code changes. Test Case 3: Basic User Interactions: Sanity testing might involve checking if users can still perform basic actions like liking posts, commenting and sharing content within the newsfeed. This ensures that core user interactions have not been unintentionally impacted by the algorithm update. While not as comprehensive as full regression testing, sanity testing provides a more in-depth check compared to smoke testing. It focuses on core functionalities and user flows likely to be affected by the recent code changes, allowing for early detection of regressions or unintended side effects. Advantages of Smoke Testing and Sanity Testing Advantages of Smoke Testing: Early Bug Detection: Smoke testing is the first line of defense, identifying showstopper bugs early in the software development cycle. This prevents wasted time and resources on further testing an unstable build. This also helps save associated costs. If users cannot even log in, further testing becomes irrelevant. Improved Efficiency: Smoke testing prioritizes a streamlined approach. It typically involves a pre-defined set of automated tests designed to assess basic functionalities quickly. This allows for rapid feedback on a build's stability, enabling developers to address issues promptly and testers to focus their efforts on more in-depth testing procedures for builds that pass the smoke test. Reduced Risk of Regression: Even though it is not a substitute for regression testing, smoke testing often includes basic checks for functionalities to ensure they have not regressed (reintroduced bugs) due to recent code changes. This helps catch regressions early, preventing them from slipping through the cracks and causing problems later in the development process. Advantages of Sanity Testing: Deeper Focus on Core Functionalities: While smoke testing verifies the absolute basics, sanity testing delves a bit deeper. It ensures not only basic functionality but also the stability of key user flows and core features after code changes. This provides a more complete picture of the build's health, identifying issues that might have slipped through smoke testing. Faster Development Cycles: By identifying critical issues early through both smoke and sanity testing, development teams can address them promptly and prevent wasted effort on testing unstable builds. This streamlined approach ultimately contributes to faster development cycles, allowing teams to iterate, fix issues and deliver software features at a more rapid pace. Reduced Release Risks: Software releases riddled with bugs can damage user experience and brand reputation. Smoke and sanity testing work together to minimize the risk of major issues reaching production. These testing techniques provide a vital layer of confidence before deploying software to a wider audience by ensuring core functionalities and basic user flows remain operational after code changes. Disadvantages of Smoke Testing and Sanity Testing Disadvantages of Smoke Testing: Limited Scope: Smoke testing focuses on verifying the absolute essentials. This is its strength for rapid feedback, but also its weakness. Complex functionalities, edge cases and non-core features might be overlooked, thereby leading to regressions or bugs in these areas remaining undetected. False Sense of Security: A successful smoke test does not guarantee a bug-free application. Its limited scope can create a false sense of security, leading to overlooking issues that might surface during later testing stages. Testers and developers tend to have a sense of accomplishment after a successful smoke test, neglecting the need for thorough follow-up testing. Reliance on Pre-defined Tests: Smoke testing often relies on pre-defined sets of automated tests. These tests usually do not adapt well to changes in the user interface or application behavior, missing newly introduced bugs. Maintaining a set of smoke tests can be time-consuming and require ongoing updates as the software evolves. Disadvantages of Sanity Testing: Subjectivity and Bias: Sanity testing often involves testers designing test cases on the fly based on their knowledge of the application and recent code changes. This flexibility can be advantageous, but it also introduces subjectivity and bias. Testers prioritize functionalities they are more familiar with, overlooking less prominent areas or edge cases. Limited Regression Coverage: Sanity testing is not a replacement for regression testing. Its focus on core functions ensures stability after code changes, but it does not guarantee the regression of functionalities that are not specifically tested. Additional regression testing procedures are imperative to ensure the overall quality and stability of the software. Documentation Overhead: Maintaining clear documentation of functionalities tested during sanity checks is necessary even though it is not as extensive as formal test scripts. This ensures consistency and facilitates knowledge sharing among testers, but it adds an overhead compared to entirely unscripted testing approaches. Finding the right balance between documentation and efficiency is key. Conclusion Smoke testing and sanity testing serve distinct yet complementary roles in the software development process. While smoke testing acts as a swift gatekeeper, sanity testing delves deeper into core functionalities. Understanding these differences allows teams to use both techniques for a more efficient and effective testing strategy. Related to Integration Testing Frequently Asked Questions 1. What is the purpose of Sanity Testing? Sanity testing acts as a quick checkpoint in software development. Its purpose is to confirm that new additions or bug fixes haven't disrupted the software's core functionality. By running a small set of tests focused on the impacted areas, sanity testing helps determine if the build is stable enough for more in-depth testing. It's a like a preliminary scan to ensure further testing efforts aren't wasted on a fundamentally broken build. 2. What is the best software testing tool? Smoke testing aims to identify major roadblocks early on, before delving into more detailed testing. The goal is to ensure the software is minimally functional and stable enough to warrant further investment in testing resources. Imagine it as a quick smoke check to see if the engine sputters to life before taking the car for a full diagnostic. 3. What is difference between smoke testing and sanity testing? Smoke testing is a quick thumbs-up/thumbs-down on core functionality, while sanity testing ensures new changes haven't broken existing features. Imagine smoke testing as a car starting and sanity testing as checking new parts. For your next read Dive deeper with these related posts! 09 Min. Read What is Smoke Testing? and Why Is It Important?

RabbitMQ vs. Kafka: Choose RabbitMQ for precision (banking, task queues) or Kafka for high-throughput streams (IoT data, social feeds). Find the right fit! 20 February 2025 09 Min. Read RabbitMQ vs. Kafka: When to use what and why? WhatsApp LinkedIn X (Twitter) Copy link Catch Queues Issues Before They Break In a digital era where 1.45 million GB of data is generated every minute , the right messaging system isn’t just a technical choice—it’s a business lifeline. Yet, here’s the kicker: RabbitMQ and Kafka , two titans of real-time data orchestration, are often pitted as rivals… when they shouldn’t be . Imagine this: A major retail platform lost $2M in sales during Black Friday because their system buckled under 50,000 concurrent orders. Post-mortem? They’d chosen Kafka for a task better suited to RabbitMQ. Spoiler: Using the wrong tool can cost millions . While RabbitMQ handles ~30,000 messages/second with ease (perfect for transactional workflows like e-commerce orders), Kafka blazes past 10 million messages/second (ideal for Uber-scale ride-tracking or real-time fraud detection). But there’s more to consider than just raw speed. In this blog, we’ll dissect: ✅ When to use RabbitMQ’s precision (think: banking transactions, task queues) vs. Kafka’s firehose (think: IoT sensor storms, social media feeds). ✅ Why 70% of enterprises using RabbitMQ also adopt Kafka ✅ The 3 critical questions that decide which tool cuts your ops costs by 40%… or leaves you debugging at 3 AM. With distributed systems a common mistake is thinking that these two systems are interchangeable, but they actually solve very different purposes and using one of them when you should be using the other can cause a lot of problems down the road so let's take a look at the main differences in their design. What Are RabbitMQ and Kafka? Before we dive into when to use each, let’s quickly define what RabbitMQ and Kafka are: RabbitMQ is a traditional message broker built for reliability and flexibility . It ensures every message reaches the right service with ACK receipts, retries, and complex routing logic. By the Numbers: Handles ~20,000–30,000 messages/second (varies with payload size and configuration). Supports 15+ protocols (AMQP, MQTT, STOMP) and advanced features like dead-letter queues. Ideal for transactional systems where exactly once delivery and order guarantee matter (e.g., payment processing, order fulfillment). Kafka isn’t just a message broker—it’s a distributed event streaming platform . Data streams in real-time, persists for days (or years), and feeds dozens of systems simultaneously. By the Numbers: Processes 1M+ messages/second per broker (a 3-node cluster can hit 10M+/second ). Latency as low as 2ms for produce/consume operations. Stores data as long as you want (default: 7 days; adjust for compliance or replayability). Feature RabbitMQ Kafka Messaging Protocols Supports AMQP, MQTT, STOMP Uses its own protocol, optimized for high throughput Routing Capabilities Direct, topic, headers, and fanout exchanges Topic-based partitioning for scalability Message Durability Ensures messages aren’t lost, even in case of failures Uses disk-based log storage for durability Setup and Management Known for user-friendly interface and easy configuration Generally, requires more initial setup and tuning Throughput High, but more suited for smaller scales Extremely high, can handle millions of messages per second Scalability Can scale, but may require more management Scales horizontally with minimal downtime Data Retention Typically transient; depends on configuration Long-term data retention configurable Stream Processing Limited native support, often integrated with other tools Robust native support for complex processing When to Use RabbitMQ? Airbnb uses RabbitMQ to manage booking confirmations. Each booking triggers a cascade of tasks (payment, notifications, calendar syncs), and RabbitMQ’s error handling ensures no guest ends up double-booked. Complex Routing of Messages: Companies dealing with multiple types of message consumers will benefit from RabbitMQ's advanced routing features. This is particularly useful in enterprise application integrations where different systems require different subsets of data. Dependable Message Delivery: Applications that cannot afford to lose messages, such as order processing systems in e-commerce platforms, will find RabbitMQ's message durability and acknowledgments invaluable. Moderate Scaling Requirements: While RabbitMQ can handle a significant load, it’s perfect for applications where the message volume is large but doesn’t reach the massive scale that would require a Kafka setup. When to Use Kafka? LinkedIn (Kafka’s birthplace) uses it to process 7 trillion messages daily . Every click, connection, and scroll event flows through Kafka to power recommendations, ads, and analytics in real time. Event Sourcing Systems: Systems that require capturing all changes to an application state as a sequence of events. Kafka can act as the backbone for such systems due to its ability to store and replay event streams. Real-Time Analytics and Monitoring: Kafka’s ability to handle high throughput makes it ideal for real-time analytics applications, such as monitoring traffic flow or user activity in large-scale web applications. Distributed Systems: Large-scale distributed systems, such as big data processing pipelines that require robust data transfer between different nodes, will benefit from Kafka’s scalable and fault-tolerant design. The Hybrid Play: Why 70% of enterprises use both? Here’s the secret: RabbitMQ and Kafka aren’t mutually exclusive . Smart teams combine them: Use RabbitMQ for transactional workflows (e.g., processing orders, user auth). Use Kafka for event streaming (e.g., tracking user behavior, logs, real-time analytics). A food delivery app uses RabbitMQ to handle order payments (ensuring no double charges) and Kafka to track rider locations, optimize routes, and update ETA in real time. Whether you're considering RabbitMQ, Kafka or both, it’s crucial to understand not only which tool fits best but also how to maintain its reliability and efficiency through rigorous testing. Since they work on processing data in real time, testing them doesn’t always come easy and straight forward. The complexity of testing message brokers Testing message queues in event-driven systems presents unique challenges, primarily due to the decoupled nature of the components involved. In these architectures, components such as Kafka producers and consumers operate independently, communicating indirectly through messages. This decoupling enhances system scalability and resilience but complicates the testing process significantly. Decoupled Components: In event-driven systems, components like producers and consumers do not have direct dependencies on each other. Instead, they interact through events or messages that are passed through a message queue like Kafka. This separation means that testing one component ( e.g., a producer sending messages ) doesn't necessarily validate the behavior of other components ( e.g., consumers processing those messages ). As a result, developers must write separate tests for each component, doubling the testing effort and complexity. Synchronizing Producer and Consumer Tests: Since producers and consumers are developed and deployed independently, coordinating tests between these components can be challenging. Tests for producers must ensure that messages are formatted correctly and sent to the right channels, while tests for consumers must verify that messages are received and processed correctly. Handling Asynchronous Behavior: Message queues inherently handle operations asynchronously. Messages sent by producers are processed by consumers at a later time, which can vary depending on the system load and other factors. Writing tests that accurately account for this asynchronous behavior is challenging. Tests must be able to handle potential delays and ensure that timing issues do not cause false failures ( e.g., a test failing because a message was not processed as quickly as expected ). When you’re trying to test event-driven stuff and the sequence of events, the problem is it’s extremely difficult to control the sequence of these things. You can’t always control it for reason that are out of your hand with event loops. This is my experience. - Chris Hartjes, Codementor PHP expert ➡️ Testing your Queues with HyperTest HyperTest addresses these challenges by automating and integrating testing processes for both producers and consumers within event-driven systems: ✅ TEST EVERY QUEUE OR PUB/SUB SYSTEM HyperTest can test Kafka, NATS, RabbitMQ, AWS SQS etc all kinds of queues or every available pub/sub system. First tool to cover all event driven systems. ✅ TEST QUEUE PRODUCERS and CONSUMERS HyperTest monitors actual calls b/w producers and consumers. Then verifies if producers are sending the right messages to the broker, and if consumers are doing the right operations after receiving those messages. 100% autonomous. ✅ DISTRIBUTED TRACING Tests real-world async flows removing the need for orchestrating test data or test environment.

Read Contract Testing Advantage: Benefits Over Traditional Methods Implement Contract Testing for Free WhatsApp LinkedIn X (Twitter) Copy link Software testing has evolved significantly, but its core principles remain steadfast. Traditionally, testing followed a waterfall model , with distinct phases like requirements gathering, unit testing , integration testing and system testing . This linear approach offered a structured method for catching bugs, but its rigidity struggled to keep pace with faster development cycles. The Agile movement ushered in a wave of change. Testing became more iterative and integrated throughout the development lifecycle. Techniques like continuous integration/continuous delivery (CI/CD) pipelines automated testing and deployment, enabling faster feedback loops and quicker bug identification. Traditional Testing vs. Contract Feature Traditional Testing Contract Testing Focus Functionality of individual services, user interactions Communication between services via APIs Scope Internal logic of services Interfaces (APIs) used for communication Development Cycle Later stages (integration, end-to-end) Earlier stages (unit, integration) Dependencies Relies on all dependent services being available Can be isolated with mocks or stubs Feedback May identify issues late in development Provides early feedback on API changes Maintainability Can be complex to maintain as system grows More focused tests are easier to maintain Debugging Can be challenging to isolate failures Easier to pinpoint failures to specific components Documentation Implicit in tests themselves Explicit contracts document API expectations The Traditional/Current Scenario of Testing Today's testing landscape embraces a hybrid approach. Traditional methods like unit testing and functional testing remain necessary foundations. However, they are complemented by a wider range of tools and techniques: Automation : Repetitive tasks like smoke testing and regression testing are increasingly automated, freeing up tester time for more strategic analysis. Tools like HyperTest simplify test case creation and execution. Shift-Left Testing : The focus has shifted towards identifying and addressing issues earlier in the development process. Unit testing and code reviews are a priority now to catch and fix bugs before they become more complex to fix. API Testing : With the rise of APIs as the communication backbone of modern applications, API testing ensures smooth data exchange between different components. Performance Testing : The user experience hinges on application responsiveness. Performance testing evaluates how the software behaves under load, identifying potential issues and ensuring scalability. The future of testing lies in continuous improvement with technologies like Artificial Intelligence and Machine Learning being explored for automating test case generation and defect identification. Need for Contract Testing Traditional testing approaches often struggle to keep pace with the constantly evolving nature of microservices. This is where contract testing steps in, offering a solution that is both compelling and with significant advantages. Contract testing fosters collaboration by establishing clear agreements (contracts) between services. These contracts define the expected data format, content and delivery protocols. It is like building a house — traditional testing might focus on the structural integrity of individual walls. Contract testing, however, ensures the walls (services) fit together seamlessly, with doors and windows (APIs) aligning perfectly. Contract testing identifies communication problems before deployment by verifying adherence to contracts during development and testing. This prevents costly bugs and regressions from impacting the live environment. Contract testing also simplifies maintenance within the microservices ecosystem. Changes to one service will not necessarily break functionalities in others as long as services adhere to established contracts. This ensures that microservices autonomy is maintained and the development process is streamlined. Understanding Contract Testing We have learnt that contract testing establishes clear agreements (contracts) between microservices, outlining the data format, content and delivery expectations. These contracts define how services communicate with each other. Here is the essence of contract testing and how we can understand it better: Consumer-Driven: Individual microservices define their data needs from other services (providers). API-Centric Focus: Contract testing emphasises the interfaces (APIs) through which services interact. The focus is on verifying that these communication channels function as intended. Shift-Left Testing: Contract testing allows for early detection of communication problems. This proactive approach prevents delays and ensures a smooth flow of information within the microservices ecosystem. Contract testing , thus, promotes smoother data exchange, minimises integration challenges and ultimately, contributes to the overall reliability and efficiency of the entire system. Advantages of Contract Testing The microservices revolution has brought agility and scalability to software development, but ensuring hassle-free communication between independent services can be a challenge. Here is where contract testing shines, offering a multitude of advantages that enable developers and testers to work through this complex model. Improved Test Isolation: One of the key contract testing advantages lies in its ability to isolate tests for individual microservices. Consumer services can be tested against pre-defined contracts, thus, eliminating the need for a fully deployed provider service. This fosters faster development cycles and allows testers to focus on specific functionalities within each service. Early Detection of Integration Issues: Traditional testing approaches might identify integration problems only after services are deployed and interacting in the live environment. Contract testing enables early detection of these issues. Contract testing helps identify communication problems before deployment by verifying adherence to contracts during development and testing, preventing expensive bug fixes and regressions. Reduced Testing Effort: Contract testing reduces overall testing effort by focusing on verifying API functionality against pre-defined agreements thereby freeing up time for other testing activities or strategic analyses. Better Support for Microservices Architecture: The microservices architecture lives on independent development and deployment of services. However, this autonomy can lead to challenges in maintaining compatibility between services. Contract testing offers better support for this architecture. Changes to a service will not necessarily break functionalities in other services with well-defined contracts in place, as long as they adhere to the established communication protocols. This promotes agility and simplifies maintenance within the microservices ecosystem. How Contract Testing Differs from Traditional Testing Methods? Software development demands innovative testing approaches. While traditional testing methods have served us well, the rise of microservices architectures necessitates a shift in perspective. Contract testing is an alternative that offers distinct advantages over its predecessors. Here is how contract testing breaks the mould: Focus on Communication: Traditional testing methods often focus on individual service functionalities or user interactions. Contract testing, however, prioritises establishing clear communication channels between services. It acts like a negotiator by ensuring services " speak the same language" by defining data format, content and delivery expectations. Early Integration Testing: Traditional integration testing typically occurs later in the development lifecycle, mainly after individual services are built. Contract testing, on the other hand, facilitates early integration testing. Communication issues are identified and addressed before deployment by verifying adherence to contracts during development, preventing costly delays and regressions. Consumer-Driven Approach: Traditional testing approaches often follow a top-down strategy. Contract testing instead has a consumer-driven mindset. Individual microservices (consumers), define their data needs from other services (providers). This ensures each service receives the data it understands and can process effectively. Focus on Interfaces (APIs): Traditional testing might focus on the internal workings of services. Contract testing, however, emphasises the interfaces (APIs) through which services interact. The focus is on verifying that these communication channels function as intended, regardless of the internal logic within each service. Implementation of Contract Testing Microservices come with a unique testing challenge: ensuring hassle-free communication between these independent entities. Contract testing is a solution that fosters collaboration and simplifies testing in this distributed environment. Here is the complete guide on how to implement contract testing in your microservices architecture.

A Complete Guide Benefits of API testing ➡️ Finding bugs at an early stage of software development: Having access to the application without a user interface or users to engage with the system is a significant advantage of API testing. It provides teams with early visibility into flaws and faults, enabling developers to address them before any impact on the interface occurs. ➡️ Saving time and Reducing testing time: A PI testing stands out for its rapid result delivery, leading to early detection of flaws and ultimately lowering overall testing costs. ➡️ Language Independence: U tilizing XML or JSON for data communication in API tests ensures language independence. This flexibility allows automation of API testing in the application using any core programming language. ➡️ Better Application Coverage: 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. Issues often arise at the intersection of two modules, where one level's scope concludes, and another level begins. 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. ⬇ Challenges in API Testing API testing, while essential, presents unique challenges that can impact the efficiency and effectiveness of your software testing process. Understanding these challenges is key to selecting the right tools and strategies. Understanding API Specifications : APIs can be complex, with intricate specifications and rules. Testers must thoroughly understand these specifications to ensure comprehensive testing. This includes grasping various request and response formats, HTTP methods, and error codes. Handling Diverse API Standards : With the existence of multiple API architectures like REST, SOAP, GraphQL, and others, a testing tool must be versatile enough to handle these varied formats. Each type of API has its own set of protocols and data formats (like JSON, XML), adding to the testing complexity. Data Validation : Ensuring the correctness of data returned by APIs is another challenge. This includes validating response data against expected data formats, schema, and values. Incorrect data can lead to application failures. HyperTest catches all kinds of regressions, be it data modifications, schema failures or status code changes. It automatically asserts for schema and data in API responses that otherwise developers have to put manually. It filters noise like changes in dynamic values that will not break the API response in production, never giving false alerts. Environment and Configuration Management : Setting up different testing environments for various stages of development (like staging, production) and managing configurations for each can be complex and time-consuming. HyperTest generated end to end API tests that can be run by developers locally, just before they push a commit. No more creating and maintaining dedicated environments to run tests.

This approach emphasizes the importance of a strong, automated testing environment to ensure that rapid changes do not compromise the quality of the software product. What is CI/CD? CI/CD stands for Continuous Integration and Continuous Deployment or Continuous Delivery, which are core practices in modern software development, particularly in the context of agile methodologies and DevOps culture. ➡️What is Continuous Integration (CI)? Continuous Integration (CI) is a practice where developers frequently merge their code changes into a central repository, preferably several times a day. Each integration is verified by an automated build and automated tests to detect integration errors as quickly as possible. This approach minimizes the integration challenges that can occur when waiting for release day to merge all developers' code into the release branch. 👉Early Bug Detection 👉Improved Quality 👉Increased Transparency 👉Reduced Risk ➡️What is Continuous Delivery (CD)? Continuous Deployment and Continuous Delivery (CD) a re practices that extend CI. They aim to automate the software release process as much as possible. Continuous Delivery ensures that every change to the codebase is automatically deployable. This doesn't mean every change is deployed to production, but it's ready for deployment. Continuous Delivery streamlines the process to get new features, bug fixes, and updates to the customer quickly and safely. Continuous Deployment go es a step further by automatically deploying every change that passes the automated tests into production. This means there's no manual gate at the stage of release to production; every change that makes it through the pipeline is live for users. 👉Rapid Releases 👉Reduced Deployment Risk 👉Increased Feedback Loop 👉Efficiency and Productivity Continuous integration (CI) vs continuous deployment (CD) Feature Continuous Integration (CI) Continuous Deployment (CD) Primary Goal To integrate code changes frequently into a shared repository.

Elements of a CI/CD pipeline A CI/CD pipeline is a series of steps that software must go through to be delivered to a customer. It's a cornerstone of modern DevOps practices, ensuring software updates are released reliably and efficiently. Let's break down the key elements of a CI/CD pipeline: 1. Source Control Source control, or version control, is where the journey begins. It's a system that tracks changes to code and allows for version management. For example, Git is a widely used system for source control. Teams work on their features and then commit their changes to a shared repository. git commit -m "Add new feature" git push origin master 2. Build Automation Once the code is committed, the next step is to automatically build the software. This involves compiling code, running tests, and packaging the software. Tools like Jenkins, CircleCI, or GitHub Actions are often used for this purpose. pipeline { agent any stages { stage('Build') { steps { sh 'make' } } } } 3. Automated Testing Automated tests are crucial for ensuring the quality of software. This can include unit tests , integration tests , and end-to-end tests. These tests are run every time there's a change in the codebase to catch bugs early. Tools like HyperTest seamlessly integrates with any CI pipelines, catches every logical code error, and speeds up release sign-off. 4. Code Analysis Code analysis tools assess code quality, security vulnerabilities, and technical debt. Tools like SonarQube or ESLint can be integrated into the pipeline to automatically scan the codebase with each commit. 5. Artifact Repository After the build step, the generated artifacts (like binaries or libraries) need to be stored. An artifact repository is a place to store these build outputs. Nexus and Artifactory are common choices for artifact repositories. 6. Deployment Automation This step involves automatically deploying the software to a development, testing, or production environment. Tools like Ansible, Terraform, or Kubernetes can be used for automating the deployment process. Example: - hosts: web_servers tasks: - name: Deploy latest version of the app git: repo: '' dest: /var/www/myapp 7. Monitoring and Feedback Once deployed, the application needs to be monitored to ensure its performance and health. Tools like Prometheus, Grafana, or New Relic are used for this. Feedback from this stage can be used to improve future development cycles. The Benefits of CI/CD implementation Implementing CI/CD offers numerous benefits, especially for development teams and organizations that aim to streamline their software development and deployment processes.

Princeton's SWE-Agent: Revolutionizing Software Engineering 05 Min. Read 12 July 2024 Are we close to having a fully automated software engineer? WhatsApp LinkedIn X (Twitter) Copy link Introduction In the fast-paced world of software development, engineering leaders constantly seek innovative solutions to enhance productivity, reduce time-to-market, and ensure high-quality code. Language model (LM) agents in software engineering workflows promises the possibility to revolutionise how teams approach coding, testing, and maintenance tasks. However, the potential of these agents is often limited by their ability to effectively interact with complex development environments To address this challenge researchers at Princeton published a paper discussing the possibility of a super smart SWE-agent, an advanced system that can maximise the output of LM agents in software engineering tasks using an agent computer interface or ACI, that can navigate code repositories, perform precise code edits, and execute rigorous testing protocols. We will discuss key motivations and findings from this research that can help engineering leaders prepare for the future that GenAI might is promising to create for all of us which we should not afford to ignore What is the need for this? Traditional methods of coding, testing, and maintenance are time-consuming and prone to human error. LM agents have the capability to automate these tasks, but their effectiveness is limited by the challenges they face in interacting with development environments. If LM agents can be made to be more effective at executing software engineering work, it can help engineering managers reduce the workload on human developers, accelerating development cycles, and improving overall software reliability What was their Approach? SWE-agent: a system that facilitates LM agents to autonomously use computers to solve software engineering tasks. SWE-agent’s custom agent-computer interface (ACI) significantly enhances an agent’s ability to create and edit code files, navigate entire repositories, and execute tests and other programs. SWE-agent is an LM interacting with a computer through an agent-computer interface (ACI), which includes the commands the agent uses and the format of the feedback from the computer. LM agents have been so far only used for code generation with moderation and feedback. Applying agents to more complex code tasks like software engineering remained unexplored LM agents are typically designed to use existing applications, such as the Linux shell or Python interpreter. However, to perform more complex programming tasks such as software engineering, human engineers benefit from sophisticated applications like VSCode with powerful tools and extensions. Inspired by human-computer interaction. LM agents represent a new category of end user, with their own needs and abilities. Specialised applications like IDEs (e.g., VSCode, PyCharm) make scientists and software engineers more efficient and effective at computer tasks. Similarly, ACI design aims to create a suitable interface that makes LM agents more effective at digital work such as software engineering The researchers assumed a fixed LM and focused on designing the ACI to improve its performance. This meant shaping their actions, their documentation, and environment feedback to complement an LM’s limitations and abilities Experimental Set-up DataSets : We primarily evaluate on the SWE-bench dataset, which includes 2,294 task instances from 12 different repositories of popular Python packages. We report our main agent results on the full SWE-bench test set and ablations and analysis on the SWE-bench Lite test set. SWE-bench Lite is a canonical subset of 300 instances from SWE-bench that focus on evaluating self-contained functional bug fixes. We also test SWE-agent’s basic code editing abilities with HumanEvalFix, a short-form code debugging benchmark. Models : All results, ablations, and analyses are based on two leading LMs, GPT-4 Turbo (gpt-4-1106-preview) and Claude 3 Opus (claude-3-opus-20240229). We experimented with a number of additional closed and open source models, including Llama 3 and DeepSeek Coder, but found their performance in the agent setting to be subpar. GPT-4 Turbo and Claude 3 Opus have 128k and 200k token context windows, respectively, which provides sufficient room for the LM to interact for several turns after being fed the system prompt, issue description, and optionally, a demonstration. Baselines: We compare SWE-agent to two baselines. The first setting is the non-interactive, retrieval augmented generation (RAG) baselines. Here, a retrieval system retrieves the most relevant codebase files using the issue as the query; given these files, the model is asked to directly generate a patch file that resolves the issue. The second setting, called Shell-only, is adapted from the interactive coding framework introduced in Yang et al. Following the InterCode environment, this baseline system asks the LM to resolve the issue by interacting with a shell process on Linux. Like SWE-agent, model prediction is generated automatically based on the final state of the codebase after interaction. Metrics. We report % Resolved or pass@1 as the main metric, which is the proportion of instances for which all tests pass successfully after the model generated patch is applied to the repository Results The result demonstrated that LM agent called SWE-agent that worked with custom agent-computer-interface or ACI was able to resolve 7 times more software tasks that pass the test bench compare to a RAG using the same underlying models i.e. GPT-4 Turbo and Claude 3 Opus and 64% better performance to Shell-only.

Discover the essence of Behavior-Driven Development (BDD) in our concise guide—unveiling insights from its roots in TDD and ATDD. 8 December 2023 09 Min. Read What is BDD (Behavior-Driven Development)? WhatsApp LinkedIn X (Twitter) Copy link Get the full comparison sheet What is BDD (Behavior-Driven Development)? Behavior-Driven Development (BDD) is an agile software development process that encourages collaboration among developers, QA, and non-technical or business participants in a software project. It focuses on obtaining a clear understanding of desired software behavior through discussion with stakeholders. This is achieved by defining behavior in a simple, understandable language that fosters clearer communication. In BDD, the focus is on the desired behavior of the system rather than its technical implementation. This is often expressed in a simple structured format: Given [initial context], When [event occurs], Then [ensure some outcomes]. This format helps all stakeholders, including those with no technical background, to understand the system's behavior without needing to know how that behavior is achieved in the code. Features of BDD Behavior-Driven Development (BDD) is a modern approach to software development that enhances the communication and collaboration between stakeholders. Its features are designed to bring a shared understanding of the project's goals and requirements. Here's a detailed look at these features: 1. Clear and Understandable Language (Ubiquitous Language) : BDD utilizes a common, non-technical language that is easily understandable by all stakeholders, regardless of their technical expertise. This language, often based on the domain-specific language of the business, ensures that developers, testers, and business representatives are on the same page. The ubiquitous language helps in minimizing misunderstandings and misinterpretations of requirements. It translates complex technical jargon into simple, clear terms. Example : In an online booking system, the term "reservation" might be used instead of technical jargon like "database entry." Given a user has selected a flight When the user confirms the reservation Then a reservation should be created in the system 2. Specification by Example (Executable Specifications) : BDD emphasizes defining requirements through concrete examples. These examples illustrate how the application should behave in different scenarios, providing a practical and clear guide for development. This approach leads to executable specifications, where the examples can be converted into automated tests. These tests serve both as specifications and as validation that the software meets the specified criteria. Behavioral Specifications : In BDD, the functionality of an application is defined in terms of its behavior from the user's perspective. This approach shifts the focus from writing feature-based code to developing functionalities that fulfill specific user behaviors. Behavioral specifications are often written in a structured format, like Gherkin syntax, which follows the "Given-When-Then" pattern. This pattern is instrumental in defining the context (Given), the event (When), and the expected outcome (Then). Collaboration and Stakeholder Involvement : BDD fosters close collaboration between developers, testers, and business stakeholders. This collaboration is crucial in understanding and refining the project requirements. Regular interactions and discussions among team members ensure that everyone has a shared understanding of the project's goals and how each functionality should behave. Living Documentation : The scenarios and tests written in BDD serve as living documentation of the system. This documentation is always up-to-date and reflects the current state of the system. Living documentation is easily accessible and understandable, making it a valuable resource for new team members and stakeholders who need to get up to speed with the project. Customer-Centric Approach : BDD places the customer's needs at the center of the development process. By focusing on delivering features that provide real value to the user, BDD ensures that the development efforts are aligned with customer requirements and business objectives. This approach helps in building a product that truly meets the user's needs and expectations, enhancing customer satisfaction and engagement. Example : Building a feature that allows users to reset their password easily, based on customer feedback. Feature: Password Reset Scenario: Resetting a forgotten password Given the user has forgotten their password When the user requests a password reset Then they should receive a password reset email 3. Integration with Agile Practices : BDD complements and enhances other agile practices. It integrates seamlessly with methodologies like Scrum or Kanban, adding a layer of clarity and specificity to user stories and acceptance criteria. By incorporating BDD, agile teams can improve their efficiency and effectiveness in delivering high-quality software.

Example : In a project for an e-commerce application, business analysts describe a new feature for applying discount codes. They use simple language to write scenarios that are easily understood by both developers and testers, ensuring everyone is aligned on the feature's expectations. Clear and Precise Requirements : BDD helps in defining precise and unambiguous requirements. It reduces the risk of misinterpretation and ensures that the developed feature aligns with user expectations. Early Identification of Issues and Misconceptions : BDD allows for early detection of misunderstandings or issues in the requirements. Early resolution of such issues prevents costly rework in later stages of development. Example : During a scenario review session for a banking app, a tester points out a scenario that doesn’t account for currency conversion, which was overlooked in the initial requirements. Streamlined Test Automation : BDD scenarios can be directly converted into automated test scripts. Automating tests from the get-go ensures continuous validation of features and speeds up the testing process. Customer and Business Value Focus : BDD emphasizes delivering features that provide real value to the end user and the business. This approach ensures that development efforts are aligned with business goals and user needs, leading to a more successful product. Example : A retail company develops a feature to recommend products based on user browsing history, a direct outcome of a BDD session focused on enhancing user experience and increasing sales. Living Documentation : The BDD scenarios serve as up-to-date documentation of system behavior. Living documentation is invaluable for onboarding new team members and for stakeholders to keep track of the project’s progress. Example : For an evolving health tracking app, the BDD scenarios are continuously updated with each new feature, providing a current and comprehensive overview of the app’s capabilities. Facilitates Continuous Feedback and Improvement : BDD encourages ongoing feedback from stakeholders, leading to continuous improvement. This loop of feedback and improvement ensures that the final product is finely tuned to meet user requirements and business objectives. Example : After each iteration of a project management tool, stakeholders review the BDD scenarios and provide feedback, leading to immediate improvements in the next cycle. What Are the Challenges of BDD? While Behavior-Driven Development (BDD) offers significant benefits, it also presents certain challenges that teams may encounter. Understanding these challenges is key to effectively implementing BDD in a project.

So, if you’re ready to make your database issues a thing of the past, let’s get started! What is Database Testing? To have a better understanding of database testing, you must be familiar with the term “database.” It's essentially a well-organized collection of data that you can store and access electronically, which is designed for easy management and updates. You might store smaller databases on a file system, while larger ones typically reside in cloud storage. Database testing is all about making sure that the data stored in your database is correct, consistent, and reliable. It involves checking the schema, tables, triggers, and more. Essentially, it makes sure that all operations, like queries, updates, deletions, and transactions, function correctly. Here are some key points to remember: Database testing, also known as data testing or back-end testing. You can fully automate these tests, do them manually, or use a hybrid approach that combines both methods. Its key components include database schema, transactions, store procedure, field constraints and triggers. You may ask why we really need to test the database. Well, think about it: your database is the backbone of your application, holding all the crucial data that leverage its features and functionality. If the database isn't reliable, the entire application can be impacted. Let us have a brief on this in the below section. Why Test Database? Some of the common reasons why we should test our database are as follows: Avoid problems in data mapping: When there are data transfers from UI to the backend, it may pose risks like type mismatches, transformation errors, format discrepancies, duplicates, and mapping issues. When you test the database, it prevents these, securing data integrity in digital operations. Confirm data precision and integrity: Ensuring data accuracy and integrity in database testing is crucial. It will make sure that your data accurately represents real-world scenarios and stays consistent throughout its lifecycle. Validate accuracy against business needs: It allows you to understand that your data meets business needs. Accuracy matters more than volume.
