<p>Let&#8217;s talk about something important in the realm of software testing: Robustness testing. ISTQB states, “Robustness testing is the degree to which a component or system can function correctly in the presence of invalid inputs or stressful environmental conditions.&#8221;This is when we test a system or program to see how well it can handle unexpected scenarios and mishaps. </p>



<p>We want to ensure that our software can keep soldiering even if it encounters unexpected situations, like a power outage or memory overload. Nobody wants their system crashing during an important project! </p>



<p>So, in this blog, let&#8217;s look at this testing technique in detail and why it matters so much in ensuring top-notch performance from our software applications.</p>

<h2 id="h-what-is-robustness-testing"><span id="What_is_Robustness_Testing"><strong>What is Robustness Testing?</strong></span></h2>



<p>Robustness testing is software testing that evaluates the capability of a system to operate correctly in unexpected or abnormal conditions. This type of testing is designed to identify possible failures due to unexpected inputs or errors, such as invalid data, network interruptions, or power failures. The goal of robustness testing is to ensure that the system can handle errors and maintain its functions without crashing or becoming unstable, thereby maximizing the software&#8217;s reliability and reducing the risk of failure.</p>



<h3 id="h-why-is-robustness-testing-important"><span id="Why_is_Robustness_Testing_important"><strong>Why is Robustness Testing important?</strong></span></h3>



<p>Here are ten important reasons why robustness testing is important: </p>



<p>1. It uncovers hidden bugs that can cause malfunctions. </p>



<p>2. Improves the reliability and quality of software. </p>



<p>3. Increases customer satisfaction by preventing software crashes. </p>



<p>4. Helps to predict real-world scenarios for better preparedness. </p>



<p>5. Validates the security features of the software. </p>



<p>6. Identifies code weaknesses and restrictions that can be optimized. </p>



<p>7. Enhances the overall software performance across various platforms. </p>



<p>8. Helps to save time and money by avoiding costly bug fixes. </p>



<p>9. Promotes software longevity since it can withstand changes in operating environments. </p>



<p>10. Boosts user confidence in the software by assuring stable and consistent performance.</p>



<h2 id="h-types-of-testing-to-ensure-robustness-of-test-suites"><span id="Types_of_Testing_to_Ensure_Robustness_of_Test_Suites"><strong>Types of Testing to Ensure Robustness of Test Suites</strong></span></h2>



<p>Different types of testing must be done to ensure the robustness of test suites. Here we give you a list:</p>



<ol><li><strong>Functional testing </strong>&#8211; Verifies the software&#8217;s desired behavior under various scenarios. Functional testing conducts numerous tests that examine all software functionalities.</li><li><strong>Regression testing </strong>&#8211; Ensures that software changes do not result in unexpected outcomes in previously tested functionality. Regression testing ensures the software application works correctly even after changes or updates.</li><li><strong>Load testing </strong>&#8211; Examines software performance under various loads and conditions to ensure it can support expected user volume. So this type of testing simulates production loads by subjecting software to a series of tests to ensure it can handle expected traffic.</li><li><strong>Fuzz testing</strong>(Fuzzing Test) &#8211; Sends malicious input to the software to discover vulnerabilities and unexpected behaviors. After conducting fuzz testing, the program is observed for crashes, failed code assertions, and possible memory leaks.</li><li><strong>Mutation testing </strong>&#8211; Changes the software&#8217;s code to see if the test suite can detect these changes and identify issues. Mutation testing aims to detect coding or input flaws that can result in incorrect program output.</li><li><strong>Black-box testing</strong> &#8211; Tests the software&#8217;s external behavior without knowing its internal workings. The tester knows the intended output of the software but lacks knowledge of its internal workings. Functionalities, user interface usability, and conformity with external standards can all be tested using black-box testing.</li><li><strong>Security testing</strong> &#8211; Verifies the software&#8217;s resistance to attacks and potential vulnerabilities. Conducting security testing can help in identifying probable security threats.</li><li><strong>Use case testing</strong> &#8211; Examines the software&#8217;s functionality from the perspective of user scenarios. Conducting Use case testing can help in identifying potential usability issues.</li><li><strong>Negative testing </strong>&#8211; Tests how the software behaves when presented with invalid inputs and unexpected situations. It can reveal input handling or validation mistakes that may result in data loss or leave security gaps.</li><li><strong>Stress testing</strong> &#8211; Evaluate the software&#8217;s increased workload capabilities under heavy load and usage. So, it can detect concerns during intense pressure or heavy workload.</li></ol>



<h2 id="h-robustness-testing-scenarios"><span id="Robustness_Testing_Scenarios"><strong>Robustness Testing Scenarios</strong></span></h2>



<p>Specific scenarios can cause software failure due to a lack of software robustness. The scenarios that can be tested are:</p>



<p>1. Test for handling large amounts of data. </p>



<p>2. Test for unexpected inputs and edge cases. </p>



<p>3. Test for system failures and recovery. </p>



<p>4. Test for long periods of sustained usage. </p>



<p>5. Test for compatibility with various hardware and software environments.</p>



<h2 id="h-should-robustness-testing-be-automated"><span id="Should_Robustness_Testing_be_Automated"><strong>Should Robustness Testing be Automated?</strong></span></h2>

<h2 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 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 techniques help you to improve the quality of your tests and cover the code lines that are still invalid. There are primarily six techniques that are popular in the market:</p>



<h3 id="h-product-coverage"><span id="Product_Coverage">Product Coverage</span></h3>



<p>A product, here, is a software application that is built to solve some problem for a certain group of users. Product coverage measures the parts/sections of the product that have undergone testing against the total number of parts/sections of the product. It is the ratio between the tested parts to the total number of parts available for testing. Some ways of extending the technique range include making a checklist, prioritizing the product features, and automating the tests.</p>



<h3 id="h-risk-coverage"><span id="Risk_Coverage">Risk Coverage</span></h3>



<figure class="wp-block-image size-full"><img loading="lazy" 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>Another important criterion of the test coverage technique is risk coverage. It identifies all the risks associated with the software under development and tests them thoroughly to uncover bugs. The ideal way to proceed with risk coverage is to segment the tests into different categories:</p>



<ul><li>a likely scenario with a major impact</li><li>an unlikely scenario with low impact</li><li>an unlikely scenario with a major impact</li><li>a likely scenario with low impact</li></ul>



<p>Once you know what test cases come under which division, you can assign them priorities and continue the testing process.</p>



<p>Suppose you are to test an app that manages finances and personal data. In that case, identifying external and internal risks and testing all of those scenarios properly comes under risk coverage. Checking if there is any loophole in the payments page is a likely scenario with a major impact, and verifying that you can make two payments at once is an unlikely scenario with a major impact.</p>



<h3 id="h-requirements-coverage"><span id="Requirements_Coverage">Requirements Coverage</span></h3>



<p>As the name suggests, requirements coverage will measure how many requirements are tested.</p>



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



<p>Boundary value testing is a <a href="https://testsigma.com/blog/the-different-software-testing-types-explained/" target="_blank" rel="noreferrer noopener">type of testing</a> that tests the boundary values for the input values being accepted by the application. With Boundary Value Coverage, you calculate the percentage of boundary value tests executed. This technique ensures that boundary-based testing is done for all the fields across the application.</p>



<h3 id="h-compatibility-coverage"><span id="Compatibility_Coverage">Compatibility Coverage</span></h3>



<p><a href="https://testsigma.com/guides/compatibility-testing/" target="_blank" rel="noreferrer noopener">Compatibility tests</a> check the compatibility of an application with different platforms, browsers, and operating systems. Compatibility coverage will be the percentage of compatibility tests executed. Cross-browser testing is also a type of compatibility testing and is counted under compatibility coverage.</p>



<h3 id="h-ai-aided-test-automation"><span id="AI-Aided_Test_Automation">AI-Aided Test Automation</span></h3>



<p>The testing tools that run on AI enable self-improving and self-maintaining test suites. With this, you can rely on robust <a href="https://testsigma.com/guides/what-is-test-case/" target="_blank" rel="noreferrer noopener">test cases</a> to provide your application with better test coverage that keeps improving. <strong>Testsigma is the new-age, AI-aided test automation tool that provides:</strong></p>



<ul><li>Codeless testing – you only need to know simple English to automate tests</li><li>Self-healing test cases, so their maintenance isn’t a huge task</li><li>Reporting and analytics of the results for better collaboration across teams</li><li>Offers compatibility to multiple third-party tools, including <a href="https://www.redhat.com/en/topics/devops/what-is-ci-cd" target="_blank" rel="noreferrer noopener">CI/CD integration</a>, collaboration tools, and bug tracking</li><li>Supports Agile and DevOps approach</li><li>Executes web, application, mobile, and <a href="https://testsigma.com/guides/api-testing/" target="_blank" rel="noreferrer noopener">API testing</a> on one unified platform</li><li>You can start creating and executing your tests in minutes</li></ul>



<h2 id="h-key-takeaway"><span id="Key_Takeaway">Key Takeaway</span></h2>



<p>Testing is important, but how much testing is important? What parameters exist to help you understand if you are testing the application enough? It&#8217;s test coverage. It measures the lines of code that have been tested against the total lines of code. The idea is to ensure that you know how much testing is over and how much is still left. And for that, you follow several test coverage techniques that we have mentioned in this blog.</p>



<p>From risk coverage and product coverage to automation and boundary-level evaluation, all these techniques will help you assess your testing efforts. And for everything automation, you already have Testsigma to assist you in no-code testing with all the benefits of test coverage.

<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>



<h2 id="h-importance-of-test-suite"><span id="Importance_of_Test_Suite"><strong>Importance of Test Suite</strong></span></h2>



<p>As a test suite is a collection of test cases grouped according to a specific set of criteria, we must learn the major importance of these test suits. By organizing test cases into test suites, testers can identify and prioritize the most critical tests, ensuring that the most important aspects of the software are tested first. This helps reduce the risk of missed errors or defects during testing.</p>

<h2 id="summary"><span id="Summary"><strong>Summary</strong></span></h2>



<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>

<p>A test suite is used to organize and execute a set of tests that ensure software quality. The primary purpose of a test suite is to detect any defects or issues within an application before it is released to the end users.</p>


Test Suite vs Test Case What is the Difference

Test Suite vs Test Case: What is the Difference?


<p>Imagine you&#8217;re a chef cooking up a delicious meal for your guests. You&#8217;ve planned out your ingredients and recipe, but before you start cooking, you need to make sure your kitchen is organized and all the kitchen tools and accessories you need is within reach. This is where test implementation comes in, the crucial stage of software testing where the test plan is put into action. Just like a chef, the test manager should ensure that everything required for testing is ready and testers can start testing.</p>



<p>In this article, we will discuss what test implementation is and its pros and cons in detail. Let&#8217;s get started.</p>

<h3 id="h-what-is-test-implementation"><span id="What_is_Test_Implementation"><strong>What is Test Implementation?</strong></span></h3>



<p>Test implementation is a process of organizing and prioritizing tests and creating test data. Sometimes, if necessary, it also involves preparing test harnesses and creating automated test scripts.</p>



<p>During this stage, the Test Analyst or Test Manager makes sure that all the prerequisites are handled to initiate the test execution. They then implement the test designs as test cases, test procedures, and test data, which are then executed to verify the functionality of the software.</p>



<p>It is crucial to choose the right tests and execute them in the right order. Also, this is vital while using risk-based strategies, where testers prioritize tests based on the risks and problems.</p>



<p>If you are following the <a href="https://standards.ieee.org/ieee/829/3787/" target="_blank" rel="noreferrer noopener nofollow">IEEE829</a> standard, then you must define the below parameters too,</p>



<ul><li>Test inputs</li><li>Expected test results, and</li><li>Steps to follow for each test process</li></ul>



<p>These will be documented together, and test data will be stored in database tables, flat files, etc.</p>



<h3 id="h-responsibilities-of-a-test-manager-in-the-test-implementation-phase"><span id="Responsibilities_of_a_Test_Manager_in_the_Test_Implementation_Phase">Responsibilities of a Test Manager in the Test Implementation Phase</span></h3>



<p>Another important part of the implementation phase is that the Test Manager should ensure that the testing team is ready to execute the test design.</p>



<p>The following are some of the responsibilities of a Test Manager in this phase:</p>



<ul><li>Ensuring that all the test procedures are organized and available to testers.</li><li>A guideline of who will execute what test cases, when, and test data for testing.</li><li>Finalizing the timeline of test execution</li><li>Ensuring that the tools to be used by testers are in place</li><li>Ensuring that the test environment for executing test data is in place</li><li>Are the test cases documented and reviewed?</li><li>Ensuring that the test environment is configured to the guidelines</li><li>Preparing a schedule for test execution, describing the order for execution of manual and automated tests.</li><li>Checking for constraints like risks and priorities</li></ul>



<h3 id="h-test-implementation-and-test-automation"><span id="Test_Implementation_and_Test_Automation"><strong>Test Implementation and Test Automation</strong></span></h3>



<p>Test implementation is not just about manual testing. It involves creating automated testing scripts as well. Automated testing should be properly implemented to ensure a good ROI (Return on Investment).In this stage, the Test Managers define the priority and the execution order of the manual and automation tests. Not just that, even the acquisition of tools required for testing, like automation testing tool, test data generation tool, framework, and more, is done in this stage.</p>

<p>The following are some of the drawbacks of implementing the tests early,</p>



<ul><li>When an Agile software development life cycle is used for software development, then the code might undergo multiple changes between consecutive iterations. This will make the entire test implementation ineffective.</li><li>Not just the Agile life cycle, using an iterative software development lifecycle will also affect the code between iterations.</li><li>The above scenarios will make the predefined tests obsolete and might require continuous maintenance.</li><li>Even while using a sequential life cycle like the Waterfall model for product development, if the project is not managed properly and if the requirements keep changing later, then early test implementation is ineffective.</li></ul>



<p>Hence, the Test Manager must consider the below factors before the test implementation process,</p>



<ul><li>Identify the type of Software development life cycle used for product development</li><li>Features that require testing</li><li>Define how frequently the requirements may change in the later stages of the project lifecycle</li><li>Possibility of code changes between two iterations</li></ul>



<h2 id="h-advantages-of-early-test-implementation"><span id="Advantages_of_Early_Test_Implementation">Advantages of Early Test Implementation</span></h2>



<p>Early test implementation is a good practice. Let&#8217;s discuss some of the advantages of early test implementation,</p>



<ul><li>Concrete test cases provide practical examples of how the application behaves.</li><li>Also, domain experts find it simple and easy to verify concrete tests rather than non-concrete business rules.</li><li>It helps identify any weaknesses in software specifications.</li><li>It further promotes collaboration between testers, developers, and other members of the project team.</li></ul>



<p><em>Note &#8211; If you&#8217;re wondering what a concrete test case is, a concrete test case is a specific test scenario with predefined input values, expected results, and execution steps.</em></p>

<h2 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 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 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 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 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><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 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 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><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 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" 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><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" 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 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>

<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 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><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 src="https://images.storychief.com/account_36412/image_c16ec456872814f4201ea32d8adda958_2000.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 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 src="https://images.storychief.com/account_36412/image_e6a57381fb6b6df9baffdeabb9564c59_2000.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 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>

<h2 id="h-what-is-defect-triage"><span id="What_is_Defect_Triage"><strong>What is Defect Triage?</strong></span></h2>



<p>In software testing, defect triage, or bug triage, is necessary for efficient resource use for bug fixes. During bug triage, a bug or defect is reviewed, assigned a priority, and according to the priority, is either assigned to a developer for fixing or deferred to the next release.</p>



<h2 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><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 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><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 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><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>



<h2 id="h-what-are-the-roles-and-responsibilities-of-the-triage-team-during-the-defect-triage-meeting"><span id="What_are_the_Roles_and_Responsibilities_of_the_Triage_Team_during_the_Defect_Triage_Meeting"><strong>What are the Roles and Responsibilities of the Triage Team during the Defect Triage Meeting?</strong></span></h2>



<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><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>
