<h2 class="wp-block-heading" id="h-why-are-test-coverage-techniques-important-for-test-automation"><span id="Why_Are_Test_Coverage_Techniques_Important_for_Test_Automation">Why Are Test Coverage Techniques Important for Test Automation?</span></h2>



<p>Automated testing makes use of tools and test scripts to validate the application. The only manual intervention in automated testing is when testers write and run the scripts. Translating the manual cases to automation covers many scenarios to test the application in lesser time. </p>



<p>Thus, better <a href="https://testsigma.com/blog/test-coverage/" target="_blank" rel="noreferrer noopener">test coverage</a> can be achieved sooner. With test automation, you can also focus on areas that are easily missed or difficult to test manually. For instance, checking UI changes manually might seem easy, but pixel-by-pixel comparison and the right font and size can be accurately validated using visual test automation. You can use test coverage techniques and automation to analyze the priority of the test case and run them to get results. </p>



<p>One example of this could be an application that consists of multiple research papers, but only users with valid credentials can access them. In that case, identifying the correct logins and sessions per user is a critical task that is difficult to check with <a href="https://testsigma.com/guides/manual-testing/" target="_blank" rel="noreferrer noopener">manual testing</a>. Combining test coverage techniques with automation will clearly determine the areas that need attention and also provide quick testing of the complete scenario. </p>



<p>For automated testing, choose tools that support the implementation of test coverage techniques we are about to discuss in this blog. Testsigma is an AI-based test automation tool that automates your test cases using these techniques, which we will discuss in later sections.</p>



<p>Read here &#8211; <a href="https://testsigma.com/blog/test-coverage-metrics/" target="_blank" rel="noreferrer noopener">Test Coverage Metrics</a></p>



<h2 class="wp-block-heading" id="h-test-coverage-techniques-you-should-know"><span id="Test_Coverage_Techniques_You_Should_Know">Test Coverage Techniques You Should Know</span></h2>



<p>Test coverage is a metric to determine how much of your software application has been tested. It helps QA teams identify untested areas, measure testing effectiveness, and ensure better product quality. A higher test coverage percentage generally indicates that more parts of the code, features, or requirements have been verified through tests. However, 100% coverage doesn’t always mean the software is defect-free; tests have exercised all defined parts.</p>



<h3 class="wp-block-heading" id="h-product-coverage"><span id="Product_Coverage">Product Coverage</span></h3>



<p>A Product coverage measures the extent to which all product features, modules, and user flows have been tested. It ensures that every critical part of the application, whether it’s a login page, shopping cart, or dashboard, is validated. Teams can track this using feature-based test matrices or by automating repetitive tests across functionalities.<gwmw style="display:none;"></p>



<h3 class="wp-block-heading" id="h-risk-coverage"><span id="Risk_Coverage">Risk Coverage</span></h3>



<figure class="wp-block-image size-full"><img loading="lazy" decoding="async" width="2400" height="1260" src="https://testsigma.com/blog/wp-content/uploads/Slide-16_9-51.png" alt="Test coverage technique - Risk coverage" class="wp-image-29264"/></figure>



<p>Risk coverage focuses on testing areas with the highest potential for failure or business impact. Instead of testing everything equally, QA teams identify high-risk features (e.g., payment processing, authentication) and prioritize them. This technique helps maximize the testing ROI by ensuring the product&#8217;s critical parts are thoroughly verified.<gwmw style="display:none;"></p>



<h3 class="wp-block-heading" id="h-requirements-coverage"><span id="Requirements_Coverage">Requirements Coverage</span></h3>



<p>Requirements coverage measures how many of the software’s defined requirements both functional and non-functional have been validated by at least one test case. It ensures that all customer and business needs outlined during the requirements phase are tested and met before release.<gwmw style="display:none;"></p>



<p><strong>How It Works</strong><strong><br></strong>QA teams map each requirement to one or more test cases, typically using a Requirements Traceability Matrix (RTM). This mapping helps ensure there are no missing tests for any requirement and that all features behave as intended.</p>



<p>If your application has 50 documented requirements and 45 of them have corresponding test cases executed successfully, your requirements coverage is 90%.</p>



<p><strong>Why It Matters:</strong></p>



<ul class="wp-block-list"><li>Ensures full traceability from requirements to tests</li><li>Reduces risk of missing critical functionality</li><li>Helps validate that the software aligns with stakeholder expectations<strong>.</strong></li></ul>



<p>Regularly update your RTM when new requirements are added or changed to keep your coverage metric accurate.</p>



<h3 class="wp-block-heading" id="h-boundary-value-coverage"><span id="Boundary_Value_Coverage">Boundary Value Coverage</span></h3>



<p>Boundary value coverage focuses on testing at the edges of input ranges values just inside, on, and just outside defined boundaries.<gwmw style="display:none;"></p>



<p>It helps uncover defects that often occur at boundary conditions, where systems are more likely to behave unexpectedly. For each input field or parameter, define the valid input range and test around its limits.&nbsp;</p>



<p>For example, if a system accepts values from 1 to 100, the test cases should include 0, 1, 100, and 101. Suppose there are 20 boundary value test cases planned, and 18 have been executed. Your boundary value coverage = (18 ÷ 20) × 100 = 90%.</p>



<p><strong>Why It Matters:</strong></p>



<ul class="wp-block-list"><li>Detects off-by-one and edge-related defects</li><li>Improves the robustness and reliability of the software</li><li>Helps ensure input validation and error-handling logic are correctly implemented.</li></ul>



<p>Pair boundary testing with equivalence partitioning to optimize test effort, this way, you cover both typical and edge scenarios effectively.<gwmw style="display: none; background-color: transparent;"><gwmw style="display:none;"></gwmw><gwmw style="display:none;"></p>



<h3 class="wp-block-heading" id="h-compatibility-coverage"><span id="Compatibility_Coverage">Compatibility Coverage</span></h3>



<p>Compatibility coverage measures how well your application performs across different environments such as browsers, operating systems, devices, and screen resolutions. It ensures users have a consistent and functional experience regardless of the platform they use.<gwmw style="display:none;"></p>



<p>Identify all environment combinations relevant to your users for instance, Chrome on Windows, Safari on macOS, or Android vs iOS devices.</p>



<p>Then track how many of these have been tested successfully.</p>



<p>If your target matrix includes 10 browser OS combinations and you’ve tested 8 of them, your compatibility coverage is 80%.</p>



<p><strong>Why It Matters:</strong></p>



<ul class="wp-block-list"><li>Prevents environment-specific bugs that can affect user experience</li><li>Ensures cross-platform consistency and accessibility</li><li>Crucial for responsive web and mobile apps with diverse user bases.</li></ul>



<h3 class="wp-block-heading" id="h-ai-aided-test-automation"><span id="AI-Aided_Test_Automation">AI-Aided Test Automation<gwmw style="display:none;"></span></h3>



<p>AI-aided test automation leverages artificial intelligence to optimize and expand test coverage automatically. AI can identify untested areas, generate missing test cases, self-heal broken tests, and continuously update test suites.<gwmw style="display:none;"></p>



<h2 class="wp-block-heading" id="benefits-of-test-coverage-techniques"><span id="Benefits_of_Test_coverage_techniques"><strong>Benefits of Test coverage techniques</strong></span></h2>



<p>Implementing test coverage techniques helps QA teams measure, optimize, and communicate the effectiveness of their testing efforts.</p>



<ul class="wp-block-list"><li><strong>Detect Untested or Risky Areas &#8211; </strong>Highlights parts of the application that haven’t been tested, helping QA teams focus on high-risk or high-impact modules before release.</li><li><strong>Improve Product Quality and Reliability &#8211; </strong>Ensures every feature, requirement, and edge case is validated, reducing the chance of defects slipping into production.</li><li><strong>Ensure Requirement Traceability &#8211; </strong>Links each requirement to test cases, confirming that all business goals and user expectations are thoroughly tested.</li><li><strong>Optimize Testing Efforts &#8211; </strong>Prevents redundant testing and directs QA focus toward areas with low coverage or higher risk, improving efficiency and test ROI.</li><li><strong>Build Stakeholder Confidence &#8211; </strong>Provides measurable QA metrics that increase transparency and trust between development, QA, and management teams.</li><li><strong>Enable Data-Driven QA Decisions &#8211; </strong>Offers factual insights to guide prioritization, resource allocation, and release readiness decisions instead of relying on intuition.</li></ul>

<h3 class="wp-block-heading" id="h-what-is-a-test-case"><span id="What_is_a_test_case">What is a test case?</span></h3>



<p>A <a href="https://testsigma.com/guides/what-is-test-case/" target="_blank" rel="noreferrer noopener">test case</a> is a set of instructions determining whether a software or system behaves as expected. A test case generally outlines the various inputs and outputs for a particular scenario and provides step-by-step instructions on executing that scenario. It can also include information about the expected result after executing those steps.</p>



<p>Test cases are essential because they help identify bugs and issues early, saving time and money in the long run. Ensuring high-quality software products that meet customer requirements would be much harder without them.</p>



<h3 class="wp-block-heading" id="h-what-is-a-test-suite"><span id="What_is_a_Test_Suite">What is a Test Suite?</span></h3>



<p>A test suite is a set of tests designed to check the functionality and performance of the software. It collects individual test cases based on their specific purpose or characteristics.</p>

<p>This blog taught us about test cases, test suites, and their differences. A test case is a set of instructions that outlines how to execute a specific test on a particular aspect of the software, while a test suite is simply a collection of multiple related tests. In other words, any software testing endeavor&#8217;s pieces can be classified as test cases. Still, when packaged together into an organized group, they form the larger umbrella known as a Test suite.</p>

Test Suite vs Test Case What is the Difference

Test Suite vs Test Case: What is the Difference?


<p>Before getting into the topic of Non-Regression testing, Let&#8217;s brush up!</p>



<p>When a new code change is made, it can mess up how the software works. Even a tiny change can cause unexpected problems or create new bugs. That&#8217;s where Regression testing comes in.</p>



<p><a href="https://testsigma.com/regression-testing#:~:text=Regression%20testing%20is%20a%20software%20testing%20process%20that%20aims,or%20system%20enhancements" target="_blank" rel="noreferrer noopener">Regression testing</a> means running tests to ensure the new code changes didn&#8217;t mess up anything already working. But sometimes, there isn&#8217;t enough time or resources to run all the tests again. In those cases, the testing team will only check the parts of the system where the changes were made. That&#8217;s called non-regression testing.</p>

<h2 class="wp-block-heading" id="h-what-is-non-regression-testing"><span id="What_is_Non-Regression_Testing"><strong>What is Non-Regression Testing?</strong></span></h2>



<p>Non-Regression Testing is a software testing technique that ensures a new or modified functionality works correctly with the assumption that the previous functionality was not affected. This technique involves testing only the evolving unit or module rather than the entire product to conserve resources and time.</p>



<h2 class="wp-block-heading" id="h-difference-between-regression-testing-and-non-regression-testing"><span id="Difference_between_Regression_Testing_and_Non-Regression_Testing"><strong>Difference between Regression Testing and Non-Regression Testing</strong></span></h2>



<p>Regression and Non-regression Testing are two software testing techniques used in software development. The below table summarizes the difference between regression testing and non-regression testing.</p>



<figure class="wp-block-table aligncenter"><table><tbody><tr><td><strong>Regression Testing</strong></td><td><strong>Non-Regression Testing</strong></td></tr><tr><td>The aim is to prevent past bugs.</td><td>The aim is to identify bugs in new functionality or features.</td></tr><tr><td>Focuses on the stability of the existing system.</td><td>Focuses on validating newly added functionality.</td></tr><tr><td>Ensures that past changes do not negatively impact existing functionality.</td><td>Ensures that new functionality or features are working as intended.</td></tr><tr><td>Performed after bug fixes, updates, or changes.</td><td>Usually performed after the completion of new functionality or features.</td></tr><tr><td>Occurs after changes to the software are made.</td><td>It occurs during the development process or after new features are released.</td></tr><tr><td>Requires existing test cases to be re-executed.</td><td>Requires new test cases to be developed and executed.</td></tr></tbody></table></figure>



<h2 class="wp-block-heading" id="h-steps-of-non-regression-testing"><span id="Steps_of_Non-Regression_Testing"><strong>Steps of Non-Regression Testing</strong></span></h2>



<p>The steps involved in Non-Regression testing include several key elements.</p>



<ol class="wp-block-list"><li>Prepare Test Cases: Test cases that test the new code changes are prepared in this stage.</li><li>Execute Test Cases: This will involve running the test cases against the modified version of the software so that any issues can be identified.</li><li>Analyze Results: After executing the test cases, we need to analyze the results. This will involve looking at the results of the tests and determining if the new change is working as impacted.</li><li>Report Findings: Report the results of the non-regression testing to the relevant stakeholders to identify any issues that need to be resolved.</li><li>Retest: The application should be retested once any new issues have been identified.</li></ol>



<h2 class="wp-block-heading" id="h-use-of-non-regression-testing"><span id="Use_of_Non-Regression_Testing"><strong>Use of Non-Regression Testing</strong></span></h2>



<p>We use non-regression testing to test new features and functionalities. This is a check to ensure that recent changes are working as expected and does not test the existing features.</p>



<h2 class="wp-block-heading" id="h-when-should-we-automate-non-regression-testing"><span id="When_should_we_automate_Non-Regression_testing">When should we automate Non-Regression testing?</span></h2>



<p>Automate non-regression testing when the software system is stable enough to be tested automatically. Check that: &#8211; There are no frequent changes to the system &#8211; There is a clear set of expected results &#8211; The cost of automating the tests is justified. However, it is important to note that not all non-regression testing can or should be automated, as some aspects may require human judgment and analysis.</p>

<h2 class="wp-block-heading" id="h-what-is-test-design"><span id="What_is_Test_Design">What is Test Design?</span></h2>



<p>Test design is a process that defines how testing has to be done. It involves the process of identifying the testing techniques, test scenarios, test cases, test data, and expected test results.</p>



<p>Also, testers need to be specific about the test cases they create, such as providing specific inputs, steps, and test data for each test case.</p>



<h2 class="wp-block-heading" id="h-what-is-the-purpose-of-test-design"><span id="What_is_the_Purpose_of_Test_Design">What is the Purpose of Test Design?</span></h2>



<p>Software testing, like all processes, is an investment and is considered successful when it provides an ROI. To ensure, we are getting the <a href="https://testsigma.com/blog/roi-test-automation/" target="_blank" rel="noreferrer noopener">ROI; it has to be tracked too</a>. One factor that will create an impact on the ROI, is the effectiveness of the test strategy. An effective test design will largely dictate the effectiveness of the testing strategy, thus the ROI from the software testing process.</p>



<h2 class="wp-block-heading" id="h-when-to-create-a-test-design"><span id="When_to_Create_a_Test_Design">When to Create a Test Design?</span></h2>



<p>Test design should be created once the test conditions are defined, and adequate information is available to create the test cases of both high and low levels.</p>



<h2 class="wp-block-heading" id="h-why-is-test-design-important-for-test-automation"><span id="Why_is_Test_Design_Important_for_Test_Automation">Why is Test Design Important for Test Automation?</span></h2>



<p>Just as Test Design is important for an effective test strategy, a well-defined test design plays an important role in the success of test automation too.</p>



<p>It is a crucial activity that helps determine the effectiveness of automated test cases in identifying bugs and is highly essential for quality control and testing.<em>&#8220;More than the act of testing, the act of designing tests is one of the best bug preventers known. &#8220;</em> &#8211; says Boris Beizer.</p>



<p>For the effectiveness of test automation, you also need to have a test automation tool that supports your goals. Thus, choosing the right test automation tool is vital, as also stated by a report that said: <a href="https://research.aimultiple.com/test-automation-statistics/" target="_blank" rel="noreferrer noopener nofollow">26%</a> of companies consider finding the right tools for automation testing as their biggest challenge.</p>

<h2 class="wp-block-heading" id="h-how-is-test-design-done"><span id="How_Is_Test_Design_Done">How Is Test Design Done?</span></h2>



<p>Test design is done using several test design techniques. The following is a list of some of the top design techniques,</p>



<ul class="wp-block-list"><li>Equivalence Class Testing</li><li>State Transition</li><li>Exploratory Testing</li><li>Boundary value analysis</li><li><a href="https://testsigma.com/blog/pairwise-testing/" target="_blank" rel="noreferrer noopener">Pairwise test </a>design</li><li>Error guessing test design</li></ul>



<p>Let&#8217;s talk about some of the top techniques in the below section.</p>



<h2 class="wp-block-heading" id="h-top-test-design-techniques"><span id="Top_Test_Design_Techniques">Top Test Design Techniques</span></h2>



<p>Let&#8217;s discuss the top techniques in detail.</p>



<h3 class="wp-block-heading" id="h-1-equivalence-class-testing"><span id="1_Equivalence_Class_Testing">1. Equivalence Class Testing</span></h3>



<p>Equivalence class testing, also known as Equivalence Class Partitioning, is a test design technique that lets you partition your test data into equivalent classes or sections.</p>



<p>It aims to reduce the number of test cases required to test a product by dividing the input domain into a set of equivalence classes. You can use this whenever an input field has a range like age.</p>



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



<p>Consider a gaming website has a form that requires users to enter their age. And the form specifies that the age has to be between 18 and 60. Now, using the Equivalence Class Partitioning technique, you can divide the input range into three partitions, as follows,</p>



<ul class="wp-block-list"><li>1 to 17 (invalid)</li><li>18 to 60 (valid)</li><li>&gt;60 (invalid)</li></ul>



<p>By partitioning the input range into equal partitions, you can create test cases that cover all possible scenarios. This way, you can easily make sure that your form is working correctly without testing every possible number between 18 and 60.</p>



<h3 class="wp-block-heading" id="h-2-state-transitioning"><span id="2_State_Transitioning">2. State Transitioning</span></h3>



<p><p style="padding-bottom:30px">It is a type of black box testing that is performed to check the change in the application&#8217;s state under various inputs. This testing is used where different system transitions have to be tested.</p></p>



<div class="wp-block-image"><figure class="aligncenter size-full"><img loading="lazy" decoding="async" width="512" height="317" src="https://testsigma.com/blog/wp-content/uploads/test-design.png" alt="Test Design" class="wp-image-36779" /></figure></div>



<p><p style="padding-top:30px"><strong>State Transition Diagram</strong>Above is a state transition diagram that needs to be tested, it depicts how a system&#8217;s state changes on specific inputs. The four main components for a state transition diagram are as follows:</p></p>



<ol class="wp-block-list"><li>States</li><li>Transition</li><li>Events</li><li>Actions</li></ol>



<p>State transition testing helps understand the system&#8217;s behavior and covers all the conditions. Let&#8217;s try to understand this with an example.</p>



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



<p>Consider a bank application that allows users to log in with valid credentials. But, if the user doesn&#8217;t remember the credentials, the application allows them to retry with up to three attempts. If they provide valid credentials within those three attempts, it will lead to a successful login. In case of three unsuccessful attempts, the application will have to block the account.</p>



<p><p style="padding-bottom:30px">The below image will explain this scenario in a clear way.</p></p>



<div class="wp-block-image"><figure class="aligncenter size-full"><img loading="lazy" decoding="async" width="2400" height="1260" src="https://testsigma.com/blog/wp-content/uploads/Slide-16_9-47.png" alt="State Transitioning Example

" class="wp-image-29248" /></figure></div>



<br><h3 class="wp-block-heading" id="h-3-exploratory-testing"><span id="3_Exploratory_Testing">3. Exploratory Testing</span></h3>



<p>Exploratory testing is primarily used in Agile methods and involves outside-the-box thinking.</p>



<p>This process does not follow pre-defined test cases but instead involves testers using their knowledge, skills, and creativity to identify issues that may not have been anticipated by developers.</p>



<p>During exploratory testing, the tester will explore the software application in an unstructured way, creating and executing tests on the fly. The goal of this testing is to uncover bugs that may have been missed by other traditional testing methods.</p>



<h2 class="wp-block-heading" id="h-test-design-concepts-you-must-be-familiar-with"><span id="Test_Design_Concepts_You_Must_Be_Familiar_With">Test Design Concepts You Must Be Familiar With</span></h2>



<p>As a software tester, there are several test design concepts that you must be familiar with to create effective test cases. Here are some of the most important test design concepts,</p>



<h3 class="wp-block-heading" id="h-test-automation-pyramid"><span id="Test_Automation_Pyramid">Test Automation Pyramid</span></h3>



<p><a href="https://testsigma.com/blog/testing-pyramid/" target="_blank" rel="noreferrer noopener nofollow">Test Automation Pyramid</a> is a testing framework that helps developers and testers to build high-quality products. It emphasizes the importance of automation at each level. The pyramid consists of three levels, each representing a different type of testing as follows,</p>



<ul class="wp-block-list"><li>Unit Tests</li><li>Integration Tests</li><li>End-to-End Tests</li></ul><br>



<div class="wp-block-image"><figure class="aligncenter"><img decoding="async" src="https://s3.us-east-1.amazonaws.com/blog-assets-production.testsigma.com/blogs/wp-content/uploads/migrated_images/image_c16ec456872814f4201ea32d8adda958_2000.png_1748947564.png" alt="Test Automation Pyramid" /></figure></div>



<p><p style="padding-top:30px"><strong>Unit testing:</strong> Here, testing is done on individual units or software modules. Each unit is tested separately to ensure that it behaves as intended and meets its requirements.<strong>Integration testing:</strong> It helps verify that different modules of a software application are working as intended when they are integrated together.<strong>End-to-End testing:</strong> It involves evaluating the entire software application, from start to finish, to ensure that all components work together as expected and meet the requirements and business objectives. Also, it enables quick feedback cycles and helps developers fix bugs in a short time. It helps save time, reduce costs, and improve the overall quality of an application.</p></p>



<h3 class="wp-block-heading" id="h-test-coverage-and-code-coverage"><span id="Test_Coverage_and_Code_Coverage">Test Coverage and Code Coverage</span></h3>



<p>Both test coverage and code coverage are two related but distinct concepts in software testing. Test coverage refers to the maximum extent to which an application has been tested.</p>



<p><p style="padding-bottom:30px">Test coverage is calculated as follows,</p></p>



<div class="wp-block-image"><figure class="aligncenter"><img decoding="async" src="https://s3.us-east-1.amazonaws.com/blog-assets-production.testsigma.com/blogs/wp-content/uploads/migrated_images/image_e6a57381fb6b6df9baffdeabb9564c59_2000.png_1748947562.png" alt="Test coverage" /></figure></div>



<p><p style="padding-top:30px">For example, if you have 2000 lines of code, your test cases should be able to test the entire codebase. If only 1000 lines of code are tested out of 2000, the test coverage is 50%. Aim for 100% test coverage which means that your entire application functionality is tested to ensure a high-quality product.Code coverage specifically refers to the percentage of the code that has been covered by tests. Simply put, code coverage tells how much code is tested, and test coverage tells if your tests cover the application&#8217;s functionality or not.</p></p>



<p>Code coverage is calculated as follows,</p>



<p><strong><em>Code Coverage Percentage = (Number of lines of code executed)/(Total Number of lines of code in an application) * 100</em></strong></p>



<p>If the entire piece of code is tested, then you may consider that the code coverage is 100%. Good code coverage is considered a good metric for testing.</p>



<h3 class="wp-block-heading" id="h-test-suites-and-test-cases"><span id="Test_Suites_and_Test_Cases">Test Suites and Test Cases</span></h3>



<p>Test Suites and Test cases are interrelated terms. A test suite can be defined as a collection of test cases designed to test a specific functionality of the software. They are typically created and managed by testers.A test case is a set of instructions that defines the steps to be taken and the expected results for testing specific software functionality. Simply put, test cases are individual tests.</p>



<p><p style="padding-bottom:30px">When you automate your test cases, Testsigma &#8211; a no-code test automation tool also supports the addition, updation, and deletion of test cases and test suites. It is very easy to <a href="https://testsigma.com/docs/test-cases/manage/add-edit-delete/" target="_blank" rel="noreferrer noopener">create test cases</a> using its NLP approach. It also lets you easily manage and run automated test cases on the cloud.</p></p>

<br><h2 class="wp-block-heading" id="h-summary"><span id="Summary">Summary</span></h2>



<p>Test design is a vital aspect of software testing that cannot be overlooked. A well-designed test strategy can provide valuable insights into the quality of software, helping testers identify issues before they become major problems. Thus, it helps businesses save a lot of time, effort, resources, and cost in the long run.</p>



<p>Testing is not just about finding bugs but also about ensuring that the software meets the user&#8217;s needs and expectations. By following a structured test design approach, businesses can achieve both of these goals.</p>

<p>Test design can be created using various test design techniques, such as equivalence classes, state transition, boundary value analysis, error guessing, etc.</p>



<p>Let&#8217;s consider your website has an input field that accepts values only from 1 to 10. The test condition for the above scenario would be,</p>



<ul class="wp-block-list"><li>&lt;1 &#8211; Invalid</li><li>1 &#8211; 10 &#8211; Valid</li><li>&gt;10 &#8211; Invalid</li><li>Any three-digit number (Example &#8211; 100) &#8211; Invalid</li></ul>

<h2 class="wp-block-heading" id="h-why-do-we-need-to-have-defect-triage"><span id="Why_Do_We_Need_to_have_Defect_Triage"><strong>Why Do We Need to have Defect Triage?</strong></span></h2>



<p>Triaging defects is crucial to software development and has several advantages for the project team and the end users. Defect triage is necessary for the following reasons:</p>



<ul class="wp-block-list"><li><strong>Prioritization:</strong> Defect triage aids the development team in <a href="https://testsigma.com/blog/difference-between-priority-and-severity/" target="_blank" rel="noreferrer noopener">prioritizing defects</a> according to their importance, severity, and urgency. This minimizes the possibility of project delays and failures by ensuring that the most critical bugs/defects are fixed first.</li><li><strong>Resource allocation:</strong> Defect triage aids the development team in prioritizing defects according to their importance, severity, and urgency. This minimizes the possibility of project delays and failures by ensuring that the most critical bugs are fixed first.</li><li><strong>Improved communication:</strong> Defect triage encourages open communication among developers, project managers, and other stakeholders. It enables them to debate and agree on the importance of defects, ensuring they are all on the same page.</li><li><strong>Better quality software: </strong>Because critical bugs are taken on priority and fixed on time, it leads to a high-quality software that satisfies the demands of end users .</li><li><strong>Cost savings:</strong> Defect triage helps reduce the cost of addressing faults by resolving them early. It helps in saving costs spent later in the development process.</li><li><strong>Customer satisfaction: </strong>Defect triage ensures that the program satisfies the needs and expectations of end users. This results in improved levels of customer satisfaction.</li></ul>



<h2 class="wp-block-heading" id="h-how-often-defect-triage-needs-to-be-conducted-in-a-release"><span id="How_Often_Defect_Triage_Needs_to_be_Conducted_in_a_Release"><strong>How Often Defect Triage Needs to be Conducted in a Release?</strong></span></h2>



<p>The frequency of defect triage can vary depending on the project&#8217;s size, complexity, and urgency. However, in general, defect triage should be conducted:</p>



<ul class="wp-block-list"><li><strong>At the start of the project: </strong>A defect triage should be conducted at the beginning to identify any potential defects and establish a process for handling them.</li><li><strong>After each development phase:</strong> Defect triage should be conducted after each development phase. This ensures defects are identified and resolved before moving on to the next phase.</li><li><strong>Before each release:</strong> Defect triage should be conducted before every release. This can help to minimize the risk of defects being discovered by end-users after the software is released.</li><li><strong>Regularly:</strong> Defect triage should be conducted throughout development to identify and resolve any new defects promptly.</li></ul>



<p>The project&#8217;s needs and development process will determine the precise frequency of defect triage.</p>



<h2 class="wp-block-heading" id="h-what-result-can-be-expected-out-of-the-bug-triaging"><span id="What_Result_can_be_Expected_Out_of_the_Bug_Triaging"><strong>What Result can be Expected Out of the Bug Triaging?</strong></span></h2>



<p>Here are some of the results that can be expected from bug triaging:</p>



<ul class="wp-block-list"><li><strong>Prioritized defect list: </strong>Bug triaging helps prioritize defects based on severity, impact, and urgency, reducing the likelihood of project delays, failures and blocker bugs for customers.</li><li><strong>Optimized resource allocation: </strong>The development team can effectively manage resources by prioritizing faults and focusing on the most significant concerns.</li><li><strong>Improved communication:</strong> Bug triaging encourages open communication between developers, project managers, and other stakeholders. Allowing them to debate and agree on the importance of bugs.</li><li><strong>Reduced risk:</strong> Bug triaging helps to detect problems early. Reducing the likelihood of errors being overlooked until later stages of development or deployment.</li><li><strong>Higher quality software: </strong>Bug triaging helps to assure software quality and satisfies the demands of end users by reviewing and addressing bugs early.</li><li><strong>Improved customer satisfaction:</strong> Bug triaging ensures that the program fulfills the needs and expectations of end users. This results in improved levels of customer satisfaction.</li><li><strong>Cost savings:</strong> Bug triaging helps to reduce the cost of addressing faults by resolving them early in the development process rather than later in the process or after the product has been distributed.</li></ul>

<p>At a defect triage meeting, the triage team identifies, evaluates, and assigns issues for solutions to the development team. At the defect triage meeting, the triage team consists of&nbsp;the following:</p>



<ul class="wp-block-list"><li><strong>Facilitator:</strong> The triage team facilitator ensures everyone follows the triage protocol, gets a chance to contribute, and the team is focused on discovering and prioritizing faults.</li><li><strong>Project manager:</strong> The project manager is responsible for providing feedback on the priority of faults and ensuring the right development team member is responsible for resolving them.</li><li><strong>Quality assurance (QA) lead:</strong> The QA lead is responsible for reviewing the defects and providing input on their severity and impact on the software. They should also ensure the development team has the information to reproduce and resolve the defects.</li><li><strong>Development team representative:</strong> The development team representative advises on the viability of fixing bugs and allocating them to the proper team member with the required competence. The development team representative is responsible for providing input on the feasibility of resolving defects; assigning them to the appropriate team member with the necessary expertise.</li></ul>



<p>Bugs can be prioritized efficiently when each member is given a defined role and responsibility during the meeting.</p>
