<h2 id="difference-between-load-testing-and-stress-testing"><span id="Difference_between_Load_Testing_and_Stress_Testing"><strong>Difference between Load Testing and Stress Testing</strong></span></h2>



<p>In this article, we will delve into the intricacies of load testing and stress testing, uncovering their fundamental differences and shedding light on how they contribute uniquely to refining software performance.</p>



<h3 id="what-is-load-testing"><span id="What_is_Load_Testing"><strong><a href="https://testsigma.com/guides/load-testing/" target="_blank" rel="noreferrer noopener">What is Load Testing?</a></strong></span></h3>



<p>Load testing is a type of <a href="https://testsigma.com/blog/performance-testing/" target="_blank" rel="noreferrer noopener"><strong>performance testing</strong></a> that focuses on the behaviour and responsiveness of an application under normal load conditions. It simulates the expected workload on the application, such as the number of concurrent users or transactions, to evaluate its performance metrics. </p>



<p>Load Testing helps you gauge the breaking point where performance remains optimal, and user experience doesn&#8217;t take a hit. It helps identify performance bottlenecks, uncover any inefficiencies, and ensure that the application can handle the projected load without compromising its speed, stability, or user experience.</p>



<h3 id="what-is-stress-testing"><span id="What_is_Stress_Testing"><strong><a href="https://testsigma.com/blog/software-stress-testing/" target="_blank" rel="noreferrer noopener">What is Stress Testing?</a></strong></span></h3>



<p>Stress testing is another fundamental performance testing technique aimed at assessing an application&#8217;s robustness and reliability under extreme and challenging conditions.&nbsp;</p>



<p>Unlike load testing, stress testing pushes an application beyond its normal load conditions.&nbsp;</p>



<p>The primary objective of stress testing is to identify the breaking point of the system, understand how it behaves under extreme stress, and evaluate its ability to recover gracefully from any failures or crashes.&nbsp;</p>



<p>This type of testing helps uncover vulnerabilities, bottlenecks, and weaknesses in the application&#8217;s architecture, enabling developers to fortify the system and enhance its overall performance and stability.</p>



<h2 id="load-testing-vs-stress-testing"><span id="Load_Testing_Vs_Stress_Testingnbsp"><strong>Load Testing Vs Stress Testing&nbsp;</strong></span></h2>



<p>Load testing is primarily focused on assessing the performance of a system under anticipated or typical user loads. The primary objective is to ensure that the system functions smoothly and efficiently under regular, expected conditions. Think of it as evaluating how well your car runs during everyday city driving or highway cruising.&nbsp; Load testing helps answer questions like:</p>



<ul><li>Can the application handle the expected number of users without slowing down?</li><li>Is the system responsive under typical user interactions?</li><li>Are the response times within acceptable limits under normal usage?</li></ul>



<p>In essence, load testing assures that your application will perform adequately when it encounters the expected traffic load, ensuring a good user experience under usual circumstances.</p>



<p>On the flip side, stress testing is all about pushing the system to its limits and beyond. The main aim here is to evaluate how well the system copes with extreme and adverse conditions that exceed its standard operational boundaries. Imagine testing how your car handles the harshest off-road terrain or extreme weather conditions. Stress testing seeks answers to critical questions such as:</p>



<ul><li>What happens when the system faces an unexpected surge in user traffic?</li><li>How does the application behave when hardware components fail unexpectedly?</li><li>Can the system recover gracefully from sudden and intense stress?</li></ul>



<p>Stress testing goes beyond everyday scenarios to identify vulnerabilities and weaknesses that could lead to system failures under exceptional circumstances. It&#8217;s like stress-testing a bridge to ensure it can withstand the most severe earthquakes or storms.</p>



<h2 id="what-are-the-best-practices-for-load-testing-and-stress-testing"><span id="What_are_the_Best_Practices_for_Load_Testing_and_Stress_Testing"><strong>What are the Best Practices for Load Testing and Stress Testing?</strong></span></h2>



<p>Some of the best practices for load and stress testing, or any type of performance testing, are as follows,</p>



<ul><li>Always begin with a performance baseline. A solid baseline is crucial to identify and measure performance bottlenecks for improvements or declines over time.</li><li>Prioritize your performance tests since covering every user workflow is impractical, given the various types available. Focus on the most essential workflows initially.</li><li>Integrate performance testing into your CI/CD pipeline. Run performance tests as part of continuous integration and deployment to ensure continuous testing. Ad hoc approaches are rarely effective in practice.</li><li>Allocate time for addressing any performance issues. Performing performance tests in the early stages of development allows much time for fixing issues before the product goes to production. Implementing a shift left approach has a remarkable impact on testing.</li></ul>

<h2 id="h-what-is-an-isolation-testing"><span id="What_is_an_Isolation_Testing">What is an Isolation Testing?</span></h2>



<p>Isolation testing is a <a href="https://testsigma.com/guides/software-testing/" target="_blank" rel="noreferrer noopener">software testing</a> technique that isolates individual components or units of code from each other to test them independently. This helps to identify and fix defects early in the development process before they can cause problems in other parts of the system.</p>



<p>As Kent Beck, a software engineer and agile advocate, said, &#8220;The best way to find bugs is to isolate them.&#8221; This is because isolation testing can help to narrow down the scope of a defect, making it easier to find and fix.</p>



<p>Testing is a never-ending journey, essential for the quality of any software. By developing our knowledge of testing techniques like isolation testing, we can ensure that our software is free of defects and meets the needs of our users.</p>



<h2 id="h-characteristics"><span id="Characteristics">Characteristics</span></h2>



<p>The characteristics of isolation testing in more detail.</p>



<p><strong>Time-consuming:</strong> Isolation testing is time-consuming because each unit or component must be tested individually. This can be especially time-consuming for large or complex systems.</p>



<p><strong>Stubs and drivers:</strong> Stubs and drivers are software components used to simulate the behavior of external dependencies. This allows the unit or component being tested to be isolated from the rest of the system. Stubs provide the expected input to the unit or component, while drivers collect the output from the unit or component.</p>



<p><strong>Expensive:</strong> Isolation testing can be expensive because it requires the creation of stubs and drivers. Additionally, the cost of isolation testing can increase as the size and complexity of the system increases.</p>



<p><strong>Atomic in nature:</strong> Isolation testing is atomic, meaning that each unit or component is tested independently. This ensures that interactions with other code do not cause defects.</p>



<p><strong>Verifies the output of each one of those interfaces/subsystems precisely:</strong> Isolation testing verifies the output of each unit or component precisely. This ensures that the unit or component is producing the expected results.</p>



<p>Overall, isolation testing is a valuable method to help identify defects early and improve software quality. Yet, knowing the time, cost, and other challenges associated with isolation testing is essential.</p>



<p>Here are some additional tips for conducting isolation testing:</p>



<ul><li>Use a test framework to automate the testing process. This can help to save time and improve efficiency.</li><li>Use a mocking framework to create stubs and drivers. This helps simplify the testing process and improve accuracy.</li><li>Focus on testing the most critical units or components first. This will help ensure the system&#8217;s most essential parts are thoroughly tested.</li><li>Integrate isolation testing into your continuous integration (CI) pipeline. This will help ensure that tests are run frequently, and defects are detected early.</li></ul>



<p>By following these tips, you can conduct isolation testing effectively and efficiently.</p>



<h2 id="h-the-need-for-isolation-testing"><span id="The_Need_for_Isolation_Testing">The Need for Isolation Testing</span></h2>



<p>Isolation testing is essential because it can help identify bugs more quickly, prevent bugs from being introduced into other codes, and improve software performance.&nbsp;</p>



<ol><li><strong>Identifying bugs more easily:</strong> When a specific application unit is tested in isolation, there are fewer variables to consider, making it easier to determine the cause of a bug. This can save time and effort in debugging.</li></ol>



<ol start="2"><li><strong>Preventing bugs from being introduced:</strong> When a particular application unit is tested in isolation, it is less likely to interact with each other unexpectedly, which can lead to bugs. This can improve the overall quality of the software.</li></ol>



<ol start="3"><li><strong>Improving performance:</strong> When a certain application unit is tested in isolation, it can be optimized for efficiency without worrying about how it interacts with other codes. This can improve the performance of the software.</li></ol>



<h2 id="h-isolation-testing-in-performance-testing"><span id="Isolation_testing_in_performance_testing">Isolation testing in performance testing</span></h2>



<p>In performance testing, isolation testing is a technique that isolates individual system components or functionalities to evaluate their performance separately. This helps to identify performance bottlenecks, resource utilization problems, or scalability issues within specific components of a complex software system.</p>



<p>By isolating and testing individual elements, performance testers can optimize and fine-tune them for better overall system performance. It also helps to simulate different load conditions and stress testing on specific components to ensure they can handle their designated tasks efficiently.</p>



<p><strong><em>For example</em></strong>, a performance tester might isolate the database server to test its performance under different load conditions. They might also isolate the webserver to test its performance under traffic conditions. By isolating these components, the performance tester can identify any performance bottlenecks and make necessary adjustments to improve performance.</p>



<h2 id="h-isolation-testing-in-unit-testing"><span id="Isolation_testing_in_unit_testing">Isolation testing in unit testing</span></h2>



<p>In unit testing, isolation testing is the practice of testing a single unit or module of code in isolation from the rest of the application. This involves isolating the unit under test from external dependencies, such as databases, web services, or external libraries, using mock objects or stubs.</p>



<p>This approach ensures that any failures or issues detected during testing are specific to the unit being tested, allowing for easier debugging and more robust code development.&nbsp;</p>



<p><strong><em>For example,</em></strong> a unit tester might isolate a function to test its functionality. They might mock out the database dependency so that the function does not connect to the database. This allows the tester to focus on testing the function&#8217;s logic without worrying about the database.</p>



<h2 id="h-test-isolation-in-end-to-end-testing"><span id="Test_Isolation_in_End-to-End_Testing">Test Isolation in End-to-End Testing​</span></h2>



<p>In end-to-end testing, test isolation involves executing tests for individual user journeys or specific functionalities within a complete application workflow. By isolating these tests, testers can independently validate the behavior of specific features, user interactions, or scenarios.</p>



<p>This approach helps identify defects or discrepancies within specific application parts, ensuring they work correctly before testing the entire end-to-end flow. Test isolation in end-to-end testing enhances debugging efficiency and accelerates issues&#8217; identification and resolution.</p>



<p><strong><em>For example,</em></strong> an end-to-end tester might isolate the login functionality to test it independently. They could create a test case that logs in a user and then verifies that the user is logged in. This allows the tester to focus on testing the login functionality without worrying about the rest of the application.</p>



<h2 id="h-test-isolation-in-component-testing"><span id="Test_Isolation_in_Component_Testing">Test Isolation in Component Testing​</span></h2>



<p>In component testing, test isolation focuses on testing individual software components, such as modules, classes, or functions, in isolation from the broader system. This approach ensures that each component functions as intended and adheres to its specifications.</p>



<p>Test isolation in component testing is particularly valuable for verifying the correctness of the components&#8217; algorithms, logic, and data processing. It allows for comprehensive testing of each element&#8217;s functionality independently, contributing to the overall reliability and quality of the software components.</p>



<p><strong><em>For example,</em></strong> a component tester might isolate a class to test its functionality. They might do this by creating a test case that calls the class&#8217;s methods and verifies that they return the expected results. This allows the tester to focus on testing the class&#8217;s functionality without worrying about the rest of the application.</p>



<h2 id="h-advantages"><span id="Advantages">Advantages</span></h2>



<p>There are many advantages to isolation testing, including:</p>



<ul><li><strong>Early defect detection:</strong> Isolation testing can help to identify defects early in the development process before they can cause problems in other parts of the system.</li><li><strong>Improved quality:</strong> Isolation testing can improve the software&#8217;s quality by ensuring each component works correctly.</li><li><strong>Reduced debugging time:</strong> Isolation testing can help reduce debugging time and cost by identifying defects early on.</li><li><strong>Improved reliability:</strong> Isolation testing can help improve the <a href="https://en.wikipedia.org/wiki/Software_reliability_testing" target="_blank" rel="noreferrer noopener">software&#8217;s reliability</a> by making it less likely to fail.</li></ul>



<h2 id="h-disadvantages"><span id="Disadvantages">Disadvantages</span></h2>



<p>There are also some disadvantages to isolation testing, including:</p>



<ul><li><strong>Can be time-consuming:</strong> Isolation testing can be time-consuming, especially if the software is complex.</li><li><strong>Can be difficult to automate:</strong> Isolation testing can be challenging, making it difficult to scale.</li><li><strong>Can give a false sense of security:</strong> Isolation testing does not test the interactions between components so it can give a false sense of security.</li></ul>

<h3 id="h-is-unit-testing-the-same-as-isolation-testing"><span id="Is_unit_testing_the_same_as_isolation_testing">Is unit testing the same as isolation testing?</span></h3>



<p>Unit and isolation testing are both techniques that involve testing smaller system components. However, there are some key differences between the two techniques.</p>



<ul><li><strong>Unit testing:</strong> Unit testing is a type of white-box testing that tests individual units of code, such as functions or methods. Unit testing aims to ensure that each unit of code works as expected and does not contain any bugs.</li><li><strong>Isolation testing:</strong> Isolation testing is black-box testing that tests a unit of code or system component in isolation from other units or components. The goal of isolation testing is to identify and isolate bugs that different system parts may cause.</li></ul>



<h3 id="h-what-is-isolation-in-testing"><span id="What_is_isolation_in_testing">What is isolation in testing?</span></h3>



<p>Isolation in testing means testing a component or unit of an application or a system independently of other units or components.</p>


Isolation Testing | What it is, When & How to Do?


<p>According to Edward A. Strollo, a professor of software engineering at Stevens Institute of Technology, &#8220;The software requirements for a product like a plane or a train are so complex that it is impossible to test the system as a whole.&#8221; And this line throws a light on how important and complex integration testing and end-to-end testing can be.</p>



<p>This blog post will explore the core differences between integration testing and end-to-end testing and why understanding these differences is crucial for successful software development.</p>



<h2 id="h-what-is-end-to-end-testing">What is end-to-end testing?</h2>



<p><a href="https://testsigma.com/end-to-end-testing" target="_blank" rel="noreferrer noopener">End-to-end</a> testing is a software testing technique that verifies the entire software system from start to finish. It tests all the integrated components of the system to ensure that they work together as intended. End-to-end testing aims to identify any potential defects or problems that may occur when real users use the system.</p>



<p>This testing technique is especially important for complex software systems, where integrating different components can be complex and error-prone. By testing the entire system, end-to-end testing can ensure that the system is reliable, efficient, and user-friendly.</p>



<p>Here are some of the benefits of end-to-end testing:</p>



<ul><li>It can help identify defects not found in unit or integration testing.</li><li>It helps ensure that the system meets the user&#8217;s requirements.</li><li>It can help to improve the reliability and performance of the system.</li><li>It can help to reduce the risk of system failures.</li></ul>



<p>End-to-end testing can be time-consuming and expensive, but it is often essential for ensuring the quality of complex software systems.</p>



<p><strong>Example:</strong></p>



<p>We can have a look at a real-time example to understand this End-to-end testing better:</p>



<p><strong>Scenario:</strong> A customer purchases a product from an e-commerce website.</p>



<p><strong>Steps for the end-to-end test:</strong></p>



<ol><li>The customer navigates to the e-commerce website.</li><li>The customer searches for the product they want to purchase.</li><li>The customer adds the product to their cart.</li><li>The customer proceeds to checkout.</li><li>The customer enters their shipping and billing information.</li><li>The customer selects a shipping method.</li><li>The customer reviews their order and clicks &#8220;Place order.&#8221;</li><li>The customer receives an order confirmation email.</li><li>The customer receives their order in the mail.</li></ol>



<p>The end-to-end test would involve testing all the steps above to ensure that the entire process works as expected.&nbsp;</p>

<h2 id="h-what-is-integration-testing"><span id="What_is_Integration_testing">What is Integration testing?</span></h2>



<p>Integration testing is the process of testing how different software modules or components interact. It is a critical part of the software development process because it helps to identify and fix integration issues early on before they cause problems in the final product.</p>



<p>Integration testing is typically performed after unit testing, the process of testing individual modules or components in isolation. Integration testing ensures that the modules or components work together as expected. This is done by combining the modules or components and testing them as a group.</p>



<p>Different approaches to integration testing exist, such as top-down integration testing, bottom-up integration testing, and sandwich integration testing. The best approach to use depends on the specific software project.</p>



<p>Integration testing is an essential part of ensuring the quality of software. By identifying and fixing integration issues early on, integration testing can help to prevent costly errors and delays down the line.</p>



<p>Here are some benefits of integration testing:&nbsp;</p>



<ul><li>&nbsp;It helps identify integration issues early on.</li><li>It helps to improve the reliability and robustness of the software.</li><li>It helps to reduce the risk of costly errors and delays.</li><li>It helps to ensure that the software meets the user&#8217;s requirements.</li></ul>



<p><strong>Example:</strong></p>



<p>We can have a look at a real-time example to understand Integration testing better:</p>



<p><strong>Scenario: </strong>A customer is trying to book a flight and hotel using a travel website.</p>



<p><strong>Steps for the integration test:</strong></p>



<ol><li>The customer navigates to the travel website.</li><li>The customer enters their travel dates and destination.</li><li>The customer searches for hotels.</li><li>The customer selects the hotel.</li><li>The customer clicks on “Book Now”.</li><li>The customer moves to payment page.</li></ol>



<p>The integration test would test that integration between hotel search, select and payment works.</p>

<h2 id="h-which-test-do-you-need"><span id="Which_test_do_you_need">Which test do you need?</span></h2>



<p>If anyone asks you this &#8216;<em>which&#8217; </em>question, you should know the type of testing you need depends on the specific requirements of your software project. In general, you must perform both integration and end-to-end testing.&nbsp;</p>



<p>However, the emphasis on each <a href="https://testsigma.com/blog/the-different-software-testing-types-explained/" target="_blank" rel="noreferrer noopener">type of testing</a> will vary depending on the project. When deciding which type of testing to use, here are some factors to consider:</p>



<ul><li><strong>Complexity of the software system:</strong> If the software system is complex, you may need to perform both integration testing and end-to-end testing. This is because complex software systems often have many different modules or components that need to interact with each other. By performing integration testing, you can identify and fix any problems with the interaction between these modules or components.</li></ul>



<ul><li><strong>Risk of defects:</strong> If the software system is high-risk, you should perform more extensive, end-to-end testing. This is because high-risk software systems are more likely to have defects that could cause user problems. By performing end-to-end testing, you can identify and fix any defects that could affect the entire system.</li></ul>



<ul><li><strong>Budget and time constraints:</strong> <a href="https://testsigma.com/guides/integration-testing/" target="_blank" rel="noreferrer noopener">Integration testing</a> is less expensive and time-consuming than end-to-end testing. This is because integration testing tests a smaller subset of the software system. If you are on a tight budget or time constraint, consider prioritizing integration testing over end-to-end testing.</li></ul>



<ul><li><strong>Availability of test data:</strong> You may need to create test data for end-to-end testing, which can be time-consuming and expensive. You must have access to the necessary test data if you need help performing end-to-end testing.</li></ul>



<p>Here are some examples of when you might use integration testing:</p>



<ul><li>When testing a new module being added to an existing system.</li><li>When testing the interaction between two or more modules in a system.</li><li>When testing a system that is being modified or upgraded.</li></ul>



<p>Here are some examples of when you might use end-to-end testing:</p>



<ul><li>When testing a new system from start to finish.</li><li>When testing a system that real users are using.</li><li>When testing a system that is critical to the business.</li></ul>



<p>Ultimately, the decision of which type of testing to use is up to the software development team. The team should consider the specific requirements of the project and the factors listed above to make the best decision.</p>

<h2 id="h-what-are-test-deliverables"><span id="What_are_test_deliverables">What are test deliverables?</span></h2>



<p>Test deliverables are the tangible artifacts and documents generated during the software testing process. These items serve various purposes, from planning and execution to reporting and analysis. They are essential for tracking progress, ensuring adherence to testing standards, and providing stakeholders with valuable insights into the quality of the software under test.</p>



<h2 id="h-list-of-test-deliverables"><span id="List_of_test_deliverables">List of test deliverables:</span></h2>



<p>Imagine you&#8217;re at a hospital for treatment/surgery, and a team of expert doctors is attending you. What would you expect from them? Thorough planning, meticulous execution, and detailed documentation of the entire process, right? Well, in software testing, we have our own set of &#8220;doctors&#8221; – testers – who ensure the &#8220;health&#8221; of our software. Just like in medicine, there&#8217;s a need for precision and care in software testing, and this begins with creating the right &#8220;test deliverables.&#8221;</p>



<p>Let&#8217;s take a closer look at these test deliverables by drawing parallels with the medical industry:</p>



<h3 id="h-test-strategy"><span id="Test_Strategy">Test Strategy</span></h3>



<p>In the medical world, a doctor begins by crafting a treatment plan, which outlines the overall approach to addressing a patient&#8217;s condition. Similarly, in software testing, the Test Strategy serves as the treatment plan.&nbsp;</p>



<p>It defines the scope, risks, quality criteria, testing techniques, resources, and timelines, providing a strategic view of how testing will be conducted throughout the project.</p>



<h3 id="h-test-plan"><span id="Test_Plan">Test Plan</span></h3>



<p>Much like a doctor starts with a thorough diagnosis to understand a patient&#8217;s ailments, the Test Plan in software testing is like the initial assessment. It defines what needs to be tested, how it will be tested, and what resources are required.&nbsp;</p>



<p>The <a href="https://testsigma.com/testplan" target="_blank" rel="noreferrer noopener">Test Plan</a> is a detailed document that describes the testing approach, objectives, and methodologies. It includes the scope of testing, roles, timelines and test schedule, resource allocation, and test environment requirements.</p>



<p class="has-text-align-center"><img loading="lazy" width="485" height="341" src="https://lh4.googleusercontent.com/TzcOtWBIuCNCYUaxNIEzNNc4pJgG35oaHlHpMlpnVa5kUlEUi0hFnNTYZLYgiJavBcOHGk3mOJz2dHJK__rJeoEwVF-3U_q7-VAw-IGdykdt38j0mvbb8hwo08Dk8ZCGxzXdfYNbkKm_6qKhRUDy4_I"></p>



<h3 id="h-test-cases-test-scripts"><span id="Test_CasesTest_Scripts">Test Cases/Test Scripts</span></h3>



<p>Just as a doctor prescribes a specific treatment regimen with detailed instructions, software testers create <a href="https://testsigma.com/guides/what-is-test-case/" target="_blank" rel="noreferrer noopener">Test Cases</a> or Test Scripts. These detailed instructions guide the testing process, specifying what to test, what data to use, and the expected outcomes. They are the treatment regimen for your software.</p>



<p>Test cases/scripts detail the step-by-step instructions for executing tests, including input data, and expected results.</p>



<h3 id="h-test-data"><span id="Test_data">Test data</span></h3>



<p>A patient&#8217;s medical history is vital for diagnosis and treatment decisions. Similarly, <a href="https://testsigma.com/blog/test-data/" target="_blank" rel="noreferrer noopener">Test Data</a> in software testing provides the necessary input and configurations to execute tests. It&#8217;s like the patient&#8217;s medical history, helping testers understand the software&#8217;s behavior under various conditions.&nbsp;</p>



<p>Test Data encompasses the input values, configurations, and scenarios used during testing. Proper test data management is crucial to ensure thorough and accurate testing.</p>



<h3 id="h-test-summary-report"><span id="Test_summary_report">Test summary report</span></h3>



<p>After a doctor prescribes treatment, they regularly review the patient&#8217;s progress. Similarly, a Test Summary Report tracks the progress of testing. It provides an overview of the testing effort, including pass/fail results, coverage, and any issues encountered. This report keeps stakeholders informed, much like a progress report keeps the patient and their family updated on their condition.</p>



<p>The Test Summary Report provides a high-level overview of the testing activities and results. It includes key metrics, such as test coverage, pass/fail status, and any outstanding issues.</p>



<h3 id="h-test-closure-report"><span id="Test_Closure_Report">Test Closure Report</span></h3>



<p>When a patient&#8217;s treatment is complete, doctors prepare a discharge summary, highlighting the overall health status and future recommendations. In software testing, the<a href="https://testsigma.com/blog/test-closure-report/" target="_blank" rel="noreferrer noopener"> Test Closure Report</a> is akin to the discharge summary, signaling the readiness for deployment. It marks the end of the testing phase, summarizing the entire testing effort, lessons learned, and recommendations for future projects.</p>



<h2 id="h-role-of-test-automation-in-getting-the-test-deliverables"><span id="Role_of_Test_Automation_in_Getting_the_Test_Deliverables">Role of Test Automation in Getting the Test Deliverables</span></h2>



<p>Test automation acts as a powerful tool in the production of test deliverables by increasing efficiency, ensuring consistency, and providing detailed reporting. It allows software testing teams to meet tight deadlines, maintain high-quality standards, and deliver valuable insights into the quality of the software being tested.</p>



<div class="wp-block-image"><figure class="aligncenter is-resized"><img loading="lazy" src="https://lh5.googleusercontent.com/fbIVGHnleWwrM8El8NbBdKxAuWFl3JzIxvoBHr986wHv_I6tehK-XF_Eqcoe3UOAvn9sytbiMaWvu0CExi1m-BCB91ICNjRAFfEHxyH3PO2c164VJP9JbcmanS7OdvdrGIG2eEjxgO0QktedkBLKPcs" alt="Role of Test Automation" width="530" height="530"/></figure></div>



<p>Just like a highly efficient assistant to a doctor can help streamline patient care, test automation simplifies and enhances the process of producing test deliverables. Here&#8217;s how:</p>



<ul><li><strong>Efficiency &amp; Speed:</strong> Test automation tools can rapidly build and execute test cases and generate test results. This efficiency significantly reduces the time required to perform testing activities.&nbsp;</li><li><strong>Data Management:</strong> Test automation tools often come with data management features. They can help generate and manage test data, ensuring that the right input data is used for each test case. This is like having an automated system to maintain and update patient records, making sure the correct data is associated with each patient.</li><li><strong>Continuous Integration:</strong> Test automation can seamlessly integrate with the software development process, enabling continuous testing. With each code change or build, automated tests can be triggered automatically. This integration ensures that test deliverables, such as test results and reports, are continuously generated and readily available.</li></ul>



<ul><li><strong>Parallel Execution:</strong> Automation tools can execute multiple test cases simultaneously, increasing testing throughput. This parallel execution capability expedites the <a href="https://www.simplilearn.com/tutorials/devops-tutorial/fundamentals-of-software-testing" target="_blank" rel="noreferrer noopener">testing process</a> and accelerates the production of test deliverables.</li><li><strong>Reusability:</strong> Automated test scripts and artifact templates are reusable assets. Once created, they can be used across different testing phases, and projects, or even with minor adjustments for similar features. This reusability not only saves time but also promotes consistency across different testing efforts.</li><li><strong>Reporting:</strong> Automation tools typically provide detailed test execution reports. These reports include information such as pass/fail status, logs, and screenshots. Using these reports, generating test summary reports and test closure reports becomes more efficient and accurate, similar to how an assistant can compile and organize patient records for the doctor&#8217;s review.</li></ul>

<p>In the journey of becoming a tester, many aspirants tend to direct their focus on technology and tools. However, as a software tester, your primary focus should always be on your customers. Understanding their needs, challenges, and business objectives is essential. Assume the role of a tester for a software application “A” being built by a company “C” and start by asking yourself questions like:</p>



<ul><li>Why are your customers paying for this “A” software?</li><li>What is the business model of your customer “C”, and how does the software application “A” support it?</li><li>What are the specific business challenges or contexts that “C” has?</li><li>How can your testing efforts contribute to solving these challenges?</li><li>How does the application “A” fit in the bigger picture of “C”?</li></ul>



<p>Imagine being in your customers&#8217; shoes when they encounter frustrating software bugs or issues. How would you feel? Your role as a tester is to minimize such negative experiences and ensure a smooth, user journey.&nbsp;</p>



<p><strong>Homework: </strong>Take your favorite app. Now, as a customer of that app, write down the following:</p>



<ul><li>What makes the app so pleasurable for you?&nbsp;</li><li>What do you like the most?</li><li>What can ruin this experience in future?</li></ul>



<p>After you are done with the above points. Assume the role of a potential tester, now write down how will you test this app so that the customer experience is not ruined.</p>

<h2 id="false-positive-vs-false-negative-overview"><span id="False_Positive_VS_False_Negative_8211_Overview"><strong>False Positive VS False Negative &#8211; Overview</strong></span></h2>



<h3 id="h-what-is-false-positive-in-software-testing"><span id="What_is_False_Positive_in_Software_Testing"><strong>What is False Positive in Software Testing?</strong></span></h3>



<p>A false positive is an outcome where the model wrongly predicts the positive case.</p>



<p>if the test case is supposed to pass however due to script issues the test result is marked as fail. If you look at the application everything might be working as expected it&#8217;s just automation script marked them fail. The false positive might occur mostly due to tools, dependencies, middleware, or sometimes invalid DOM elements.</p>



<h3 id="h-what-is-a-false-negative-in-software-testing"><span id="What_is_a_False_Negative_in_Software_Testing"><strong>What is a False Negative in Software Testing?</strong></span></h3>



<p>A false negative is an outcome where the model wrongly predicts the negative case.&nbsp;</p>



<p>In testing, if the test case is supposed to fail due to functional issues or defects however test case ignores those defects and marks the test as pass. It can occur due to improper construction of test cases, false assumptions while writing the automation scripts, etc.</p>



<h2 id="h-false-positive-vs-false-negative-how-to-find"><span id="False_Positive_VS_False_Negative_How_to_Find"><strong>False Positive VS False Negative: How to Find?</strong></span></h2>



<p>Both false positives and false negatives are common in test automation. However, more than false positives, the false negatives have impact as it marks the defective application as pass.&nbsp;</p>



<p>If more of such issue start occurring in your application, the test automation test reports become unreliable. Thus, you should be very careful while writing the tests.&nbsp;</p>



<p>Let’s understand in detail how to find the false positives and false negatives.</p>



<p id="h-how-to-find-false-negatives"><strong>How to Find False Negatives?</strong></p>



<p>Finding a false negative is a lot more complicated than you think, as false negative results mark the test as passing inaccurately. False negatives can be caught only if you analyze them manually. You might not be able to validate a complete application manually if it is a complex application. However, you can put the strategy that whenever there are specific feature changes, you must ensure that all those test cases are validated manually and note down the expected result. The strategy needs to be improved based on its effectiveness.&nbsp;</p>



<p>Building a robust framework and having the right strategy are key to reducing false negatives.</p>



<p><strong>How to Find the False Positives?</strong></p>



<p>Unlike false negatives, finding false positives is easy. Standard practice in automation is to analyze the automation failures as and when the result/report appears.&nbsp; Before logging any issue as a defect, perform a double-check by reproducing the error manually.&nbsp;</p>



<p>In false positives scenarios, you can aim to go through the list of failure scenarios manually and analyze them before concluding.</p>



<h2 id="h-why-do-false-positive-and-false-negative-occur"><span id="Why_do_False_Positive_and_False_Negative_Occur"><strong>Why do False Positive and False Negative Occur?</strong></span></h2>



<p>Both False negatives and false positives can occur because of various reasons. However, the business impact of false negatives is more compared to false positives. As an automation team, you should always aim to have 0% false negatives. The false positive percentage can vary based on the application complexity and automation framework.</p>



<p id="h-reason-for-false-negatives"><strong>Reason for False Negatives</strong></p>



<ol><li>Poor Automation framework architecture</li><li>Skipping some of the conditions while designing the test case</li><li>Untrustworthy tools/packages are used for automation</li><li>Outdated packages, and libraries used in test automation</li><li>Unhandled pesticide paradox principle</li><li>Assumption of test coverage<br></li></ol>



<p id="h-reason-for-false-positives"><strong>Reason for False Positives</strong></p>



<ol><li>Automation scripts are not maintained regularly</li><li>Unstable <a href="https://testsigma.com/blog/test-environment/" target="_blank" rel="noreferrer noopener">testing environment</a></li><li>Standard locator strategies are not used</li><li>Outdated frameworks, libraries, and packages used</li><li>Underlying component issues such as Incompatible browsers, browser drivers, etc.</li></ol>



<h2 id="h-examples-of-false-negative-and-false-negative"><span id="Examples_of_False_Negative_and_False_Negative"><strong>Examples of False Negative and False Negative</strong></span></h2>



<p><br>When you hear about false positives and false negatives you may easily get confused, Let&#8217;s put it into analogy. When we compare with the medical test case, the medical test is done for the whether patient has some medical condition or not. Similarly, when it applies to software testing we can assume as below. <em>A positive test found a bug when there was a bug in the application</em>. This means that there was a bug in the application and automation testing found it, it is a true and ideal scenario.<br>Let&#8217;s take another example of COVID-19 test</p>



<p><strong>False Positive</strong></p>



<p>Suppose Person X doesn&#8217;t have COVID-19 and he provides the sample for testing. When the report arrived the test report was marked inaccurately COVID-19 positive though he doesn’t have an infection in his body.</p>



<p>When the same scenario is applied to testing, If you have a login scenario that is working as expected when you execute the automation test script it reports back Login functionality failed. In reality, there is no bug as such. This is a false positive.</p>



<p><strong>False Negative</strong></p>



<p>Suppose Person Y has covid infection and he provides the sample for testing. When the report arrived, report marked as “No Infections” which is COVID-19 negative. This is inaccurate, as in reality he had a COVID-19 infection.</p>



<p>Similarly, in software testing, you have a login scenario, which is failing to log in with a username and password. But, when you execute the automation script you get the report saying that the login test is passed. This is false negative.</p>



<p>If you are still confused, let&#8217;s put it in simple terms.</p>



<p>Automation test reporting failure without any valid failure in the application is called a false positive.</p>



<p>Automation test passing even if there is a valid failure in the application is called a false negative.</p>



<h2 id="h-false-positive-and-false-negative-importance-in-testing"><span id="False_Positive_and_False_Negative_8211_Importance_in_Testing"><strong>False Positive and False Negative &#8211; Importance in Testing</strong></span></h2>



<p>The <a href="https://www.javatpoint.com/software-engineering-software-development-life-cycle" target="_blank" rel="noreferrer noopener">Software Development Life Cycle</a>(SDLC) gives the same importance to testing as development, the reason is it aims to deliver quality products. Imagine a company has launched a car with model X, and after 6 months it finds a major issue with the car engine which can be life-critical. Now the company has to recall all the cars that are sold, and the company should provide compensation to the customer, additionally, the company might have to face lawsuits. These things might not have happened if there had been a proper check in place before releasing the car. The same thing applies to software. The quality of the application resides in the quality of the testing and testing framework. If testing itself does not report actual failures, that can incur loss and reputation damage to the organization.</p>



<p>The false negatives are scarier than the false positives. The false negatives leave the feature broken. If you are dealing with health care, defense, or automobile software the false negatives may take a toll on someone&#8217;s life. However, if the tool you choose, and the framework you build are robust and flawless then the organization gets great benefit.&nbsp;</p>



<p>In short, The good or bad quality lies in the automation framework and automation scripts.&nbsp;</p>



<p>Though the impact of false positives is lesser, if it occurs more frequently you end up with unreliable testing. The Team might have to spend a lot of time analyzing without any gain. The good news is that false positives are easy to fix especially with modern testing tools like <a href="https://testsigma.com/signup" target="_blank" rel="noreferrer noopener">Testsigma</a>. It suggests the fixes for failures, and guidance and provides technical support if you are struggling to fix the critical issue.</p>



<p>Both false positives and false negatives are critical in testing. However when we compare, the false positives are tolerable to some extent, but there is zero tolerance for false negatives.</p>



<h2 id="h-false-positive-and-false-negative-importance-in-test-automation"><span id="False_Positive_and_False_Negative_8211_Importance_in_test_automation"><strong><strong>False Positive and False Negative &#8211; </strong>Importance in test automation</strong></span></h2>



<p>False positives and false negatives are most common in <a href="https://testsigma.com/automated-web-application-testing" target="_blank" rel="noreferrer noopener">test automation</a>, however, it is not limited to test automation. If the same occurs in manual testing it will be because of human error.&nbsp;</p>



<p>The automation framework design plays a critical role when dealing with false positives and negatives. As an organization makes huge investments to set up infra for automation, skills, and resources the unreliable results may disappoint the management and it may end with questioning Return on Investment(ROI). Thus, having a robust design to tackle the false positives and false negatives is a must.</p>

<h2 id="h-how-to-choose-the-right-tool"><span id="How_to_Choose_the_Right_Tool"><strong>How to Choose the Right Tool?</strong></span></h2>



<p>As mentioned earlier, the automation framework plays a very critical role in the success of test automation. The automation framework depends on the underlying tools used. The tool should be capable enough to handle all the edge cases and should be continuously updated as technology changes.</p>



<p>As technology has evolved, many legacy automation tools have disappeared. One of the reasons is they could not align with modern technology change. Importantly their architecture was not flexible.</p>



<p>The right tool for your organization will be based on many factors such as the development framework used, cost, infrastructure, required skillsets, requirement of upskills, nature of the application, application domain, etc. The below pointers are generic and irrespective of the project domain that you need to consider while choosing the right tool.</p>



<ul><li>Don&#8217;t be biased, evaluate all possible automation tools as per the requirement</li><li>The tool should be intelligent enough to choose the best stable locator</li><li>It should provide all critical functionalities natively, as it reduces the third-party library dependency. In turn, this reduces the false positives and false negatives</li><li>It should support the DevOps ecosystem</li><li>It should align with the modern Agile framework</li><li>The reporting should be comprehensive</li><li>Consider no code automation tools if your organization is short of skills or resources.</li></ul>

<p>The best practices for reducing false positives and false negatives vary from project to project. To reduce them you need to prepare a concrete strategy while designing the test strategy document. Below is the list of the best practices that are independent of the project and application however, list is non-exhaustive.&nbsp;</p>



<ul><li>Build it right, from the beginning. Choose the right tool and build a robust framework.</li><li>Integrate the alerting and monitoring tools wherever possible</li><li>Prepare a code review checklist and make it a mandatory requirement to follow</li><li>Never write a test case based on the assumption</li><li>Use the right testing tool after careful evaluation of your requirements</li><li>Use dedicated environment for testing. Ensure it is as stable as the production environment</li><li>Cover all possible testing scenarios, and use assertion as much as possible in your test scripts.</li><li>Learn from failures, and update the checklists, and strategy documents as and when required.</li></ul>



<p>False positives and false negatives in test automation are common, however, you should always target to minimize them. Especially when it comes to false negatives you should aim for zero. False positives are unavoidable as UI testing relies on browsers and other testing components.&nbsp;</p>



<p>Choosing the right tool can help to reduce false positives. False positives mostly occur due to latency, locator, browser incompatibility, etc. If your test automation tool is smart enough to handle such issues the false positives can be easily reduced. <a href="https://testsigma.com/signup" target="_blank" rel="noreferrer noopener">Testsigma</a> is one such tool it automatically chooses the best possible locators and your test will be executed on the most stable workspaces remotely. This helps in producing the most accurate, stable, and reliable reports.</p>



<p>On the other hand, false negatives occur if you don’t write the test cases as per the requirement. False negatives require manual analysis and in-depth investigation. Remember even if you have the right toolsets, good infrastructure, and a stable application environment &#8211; if you don’t write test cases properly as per requirement then test automation will become unreliable.</p>

<p>False positives can be handled by implementing the correct design strategies while building the automation framework. If the framework is robust then there will be fewer false positives. False negatives can be reduced with code review, and test case review strategies. Additionally having the right process while developing the test cases can bring you great benefits.</p>
