<h2 id="h-what-are-edge-test-cases"><span id="What_are_edge_test_cases"><strong>What are edge test cases?</strong></span></h2>



<p>Case testing, also known as edge case testing, is a form of software testing that focuses on testing for exceptional behavior or conditions found at the boundaries of a program or system. So these unusual or rare scenarios occur at expected input or behavior boundaries. They are often the result of incorrect assumptions about how the software will be used and can result in unexpected or incorrect responses from the system. Edge cases are important to consider in the development process to ensure that the system can handle a wide range of inputs while continuing to produce expected outputs.</p>



<p>So, you know those times when you close a video(reels) on Instagram, but the sound keeps playing in the background for a few seconds? That&#8217;s a classic example of an edge case!</p>



<h2 id="h-what-is-an-edge-test-case-example"><span id="What_is_an_edge_test_case_example"><strong>What is an edge test case example?</strong></span></h2>



<p><strong>Let us look at a real-time example of an Edge case test case.</strong></p>



<p>Scenario: Log in to a website</p>



<p>Test Data: Incorrect username or password when the &#8216;Log-in&#8217; button is pressed</p>



<p>Expected Result: The user should not be able to log in, and an error message should be displayed.</p>



<p>This example explains: this is a <a href="https://testsigma.com/guides/what-is-test-case/" target="_blank" rel="noreferrer noopener">test case</a> designed to test the system&#8217;s response when incorrect username or password information is entered. The expected result of this test is that the user should not be able to log in. There will be an error message displayed. The tester can use this Edge Test Case to test the system&#8217;s functionality by entering any invalid input. This ensures the system is secure and the application provides the expected user experience.</p>



<h2 id="h-why-are-edge-cases-important-to-consider"><span id="Why_are_edge_cases_important_to_consider"><strong>Why are edge cases important to consider?</strong></span></h2>



<p><strong>If you want to know why edge cases are legit important, you must learn some cool facts first!</strong></p>



<ol><li>Edge cases can reveal flaws in a system or process that may not be apparent in typical scenarios. We can identify and address potential issues by considering edge cases before they become bigger problems.</li><li>Edge cases often represent real-world scenarios that may occur infrequently but still have significant consequences if not properly addressed. Considering these scenarios, we can ensure our systems and processes are robust enough to handle them.</li><li>Edge cases can also help us improve the user experience by identifying situations where users may encounter unexpected behavior or errors. Addressing these edge cases can make our systems more user-friendly and reduce user frustration.</li><li>Edge cases can seriously affect patient safety or financial stability in some industries, such as healthcare or finance. Viewing these scenarios, we can ensure that our systems and processes are designed to minimize risk and protect those who rely on them.</li></ol>



<h2 id="h-edge-case-testing-and-test-automation"><span id="Edge_case_testing_and_test_automation"><strong>Edge case testing and test automation</strong></span></h2>



<p>You should consider automating your edge case testing if you&#8217;re working with an application with a limited range of repeatable and controllable input values.</p>



<p>Test automation usually performs edge case testing to verify predetermined software outputs using automated tests. Automation testing ensures that a system meets the expected performance, quality, behavior, and configuration of the test case. Automated test scripts can detect problems that manual tests cannot identify. Teams often use <a href="https://testsigma.com/automated-testing" target="_blank" rel="noreferrer noopener">automated testing</a> to speed up test suites and to check edge cases on complex web applications and systems.</p>

<p>So, edge cases in software testing are scenarios outside the normal range of inputs and behaviors. They&#8217;re like the crazy outliers we must test for, just in case.</p>



<ul><li>Sometimes, we must test things we did not expect or plan for. It&#8217;s like testing the quirky and rough things that could happen but probably won&#8217;t. You want to ensure the software can handle those roughest inputs and unexpected situations.</li><li>When testers have a lot of data to work with and think the tests might fail at the highest or lowest limits of the data, they use something called<strong> Boundary Value Analysis.</strong> This means we&#8217;re checking out the upper and lower limits of input data values because we reckon that&#8217;s where our test cases could go wrong. This technique works best when we&#8217;ve got a ton of test data.</li></ul>



<p>Let&#8217;s say you&#8217;re testing a website that only allows for usernames with 6-12 characters. With boundary value analysis, you&#8217;d test the lower limit (6 characters), the exact limit (7 characters), and the upper limit (12 characters).</p>



<ul><li>Next, there&#8217;s <a href="https://testsigma.com/blog/equivalence-partitioning/" target="_blank" rel="noreferrer noopener"><strong>Equivalence Partitioning</strong></a>. This one&#8217;s about breaking up a huge dataset into smaller chunks. If we pass any random value from a chunk, we can assume that we have covered the chunk and don&#8217;t need to test everything in it separately.</li></ul>



<p>Let&#8217;s say you&#8217;re testing a website that only allows usernames with alphanumeric characters. You could partition this into two equivalence classes: all alphabetic characters and all numerical characters. You can then test one value from each of the two classes to ensure the website accepts numbers and letters.</p>



<ul><li>A team of testers can do edge case testing manually, or specialized tools can automate it.</li></ul>



<h2 id="h-how-to-do-edge-case-testing"><span id="How_to_do_edge_case_testing"><strong>How to do edge case testing?</strong></span></h2>



<p>Edge case testing is an important part of software testing that involves testing the system&#8217;s extreme or boundary conditions, often overlooked during regular testing. This testing can be done both manual and automated ways.</p>



<p><strong>The Manual Way:</strong></p>



<ul><li>Identify the edge cases: The first step is to identify the edge cases for your application. This can be done by analyzing the requirements and specifications of the system.</li><li>Create test cases: Once you have identified the edge cases, create test cases that cover these scenarios. You should include inputs at or beyond the limits of what is expected in these test cases.</li><li>Execute test cases: Execute each test case manually and observe how the system behaves under these conditions.</li><li>Record results: Record the results of each test case, including any issues or defects found during testing.</li></ul>



<p><strong>The Automated Way :</strong></p>



<p>1. <strong>Identify potential edge cases:</strong> The first step is to identify the potential edge cases in the system. This can be done by analyzing the requirements, user stories, and use cases.</p>



<p>2. <strong>Develop test scenarios:</strong> Once the potential edge cases have been identified, the next step is to develop test scenarios that cover these cases. These scenarios should be designed to test the system&#8217;s behavior under extreme conditions.</p>



<p><p style="padding-bottom:15px">3. <strong>Use automation tools: </strong>Automation tools such as <a href="https://testsigma.com/" target="_blank" rel="noreferrer noopener"><strong>Testsigma</strong></a>, <strong>Selenium</strong>, and <strong>Appium </strong>can automate the execution of these test scenarios. These tools can simulate user interactions with the system and verify its behavior under different conditions. </p></p>

</div>



<p><p style="padding-top:30px">4. <strong>Analyze results:</strong> After executing the automated tests, it is important to analyze the results to identify any issues or defects that may have been uncovered. This analysis can help improve the system&#8217;s quality by identifying areas that need improvement or further testing.</p></p>



<h2 id="h-why-do-edge-case-testing-before-release"><span id="Why_do_edge_case_testing_before_release"><strong>Why do edge case testing before release?</strong></span></h2>



<p>You might wonder about this WHY question! I will explain why we do edge case testing before the release.</p>



<p>Before product release, edge case testing is important to check how the system behaves in extreme conditions. Unexpected behavior of a system can frustrate users and make them abandon the product. </p>



<p>Edge case testing involves testing the system&#8217;s boundaries by entering values beyond normal use limits, such as providing an unusually large or negative input. This can identify and eliminate bugs or unexpected behavior in extreme use cases. Edge case testing can help provide customers with a smooth and seamless user experience.</p>



<h2 id="h-how-to-prioritize-edge-cases"><span id="How_to_prioritize_edge_cases"><strong>How to prioritize edge cases?</strong></span></h2>



<p>Prioritizing edge cases can be challenging because these are rare and unique scenarios. However, it is important to prioritize these cases as they can seriously impact the product&#8217;s user experience and overall functionality. One approach to prioritizing edge cases is considering their potential impact on user safety, legal compliance, and business goals. Also, gathering feedback from users and stakeholders can help identify which edge cases are most important to address.</p>



<h2 id="h-tips-for-edge-case-testing-in-your-development"><span id="Tips_for_edge_case_testing_in_your_development"><strong>Tips for edge case testing in your development</strong></span></h2>



<p>Are you ready to grasp some tips to do this testing? Here you go:</p>



<p>1. Think from the perspective of your users &#8211; how would they use the app, what path would they follow, if they had to do something unexpected what would it be? </p>



<p>2. Think of unlikely scenarios in terms of app usage and failures &#8211; like what if the battery died, what if a call came while app was being used, what if a notification came up.</p>



<p>3. Always have the mindset &#8211; if you can think it, the user can do it. So, never assume and always test for all possible user paths.</p>



<h2 id="h-conclusion"><span id="Conclusion"><strong>Conclusion</strong></span></h2>



<p>So, there you have it &#8211; by finding, prioritizing, and testing edge cases, you can improve the overall quality of your product and increase customer satisfaction. So, don&#8217;t overlook the edge cases &#8211; they might be the key to your product&#8217;s success!</p>

<h2 id="h-what-is-gorilla-testing"><span id="What_is_Gorilla_Testing"><strong>What is Gorilla Testing?</strong></span></h2>



<p>Gorilla Testing is a software testing method where all or most system areas are tested for a shorter time to identify significant issues quickly. This Testing is black-box testing focusing on a limited portion of an application, product, or system. </p>



<p>The goal is to identify any major flaws or problems within that area before proceeding with more thorough Testing. It is usually conducted by a relatively small amount of testers, spending a relatively short testing effort, the goal being to find as many bugs as possible in the shortest time.</p>



<h2 id="h-features-of-gorilla-testing"><span id="Features_of_Gorilla_Testing"><strong>Features of Gorilla Testing</strong></span></h2>



<p><strong>Here are some of the most important features of this testing:</strong></p>



<ul><li>A wide application testing with an emphasis on exploration and discovery.</li><li>Focused on user experience, functionality, and compatibility of the product.</li><li>Utilizes both positive and <a href="https://testsigma.com/blog/negative-testing/" target="_blank" rel="noreferrer noopener">negative testing</a> scenarios to ensure the highest quality possible.</li><li>Covers areas like functionality, usability, compatibility, etc.</li><li>Highly flexible to allow for adjustment in test cases, depending on the product&#8217;s unique characteristics.</li><li>Identifies issues and bugs and offers detailed reports on the product&#8217;s performance.</li><li>Since gorilla testing focuses only on necessary features, it saves time and resources by avoiding unnecessarily testing non-critical features.</li></ul>



<h2 id="h-importance-of-gorilla-testing"><span id="Importance_of_Gorilla_Testing"><strong>Importance of Gorilla Testing</strong></span></h2>



<p>The importance of Gorilla Testing cannot be overstated. Gorilla Testing helps developers and testers identify issues early in the software development process, saving time and money in the long run.</p>



<ol><li>It helps identify critical defects that may have been missed during other testing phases.</li><li>It ensures the system can handle unexpected and extreme inputs or scenarios.</li><li>It helps improve the overall quality of the software by identifying issues early on in the development cycle.</li><li>It helps ensure the system is robust and can handle large amounts of data or traffic.</li><li>It can also help identify performance issues and bottlenecks in the system.</li><li>It helps build confidence in the software&#8217;s ability to perform under different conditions and scenarios.</li><li>This testing can also help uncover security exposures that may have been missed during other testing phases.</li></ol>



<h2 id="h-monkey-testing-vs-gorilla-testing-usage"><span id="Monkey_Testing_vs_Gorilla_Testing_Usage"><strong>Monkey Testing vs. Gorilla Testing: Usage</strong></span></h2>



<p><strong>Let us discuss this in a super easy way:</strong></p>



<p><a href="https://testsigma.com/blog/monkey-testing/" target="_blank" rel="noreferrer noopener">Monkey Testing</a> is like randomly trying the software without special skills or training. You basically do whatever comes to mind, like clicking buttons, typing things, breaking stuff, and so on. The idea is to find any possible issues with how the software works, how user-friendly it is, and how secure it is.</p>



<p>On the other hand, you have Gorilla Testing. It&#8217;s pretty intense and needs some serious skills and knowledge. Basically, you&#8217;re purposely trying to mess up the software with a mix of know-how, system smarts, and lots of testing methods. The goal is to uncover sneaky bugs and problems the average user wouldn&#8217;t catch.</p>

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



<p>To summarize, gorilla testing is all about looking at the bigger picture. It doesn&#8217;t involve testing individual parts but rather focuses on the overall functionality and stability of the system. Unlike Monkey Testing, which randomly tests small bits of code without much thought, Gorilla Testing takes a more structured and thorough approach. It ultimately leads to better system performance and fewer failures.</p>

<p>Let me explain you in simple terms.</p>



<p><a href="https://testsigma.com/blog/how-does-testsigma-support-the-shift-left-approach/" target="_blank" rel="noreferrer noopener">Shift-left testing</a> starts testing earlier in the development cycle before the code is written. This type of testing narrows the gap between writing code and finding bugs. The goal of shift left testing is to find and fix bugs quickly and reduce the cost of fixing them. </p>



<p>Shift-right testing is the testing process later in the development cycle after the product is deployed. This type of testing focuses on verifying functionality and usability and finding and resolving customer-reported issues. Shift-right testing aims to improve the user experience and ensure the product is bug-free before releasing updates.</p>



<h2 id="h-test-automation-using-shift-left-and-shift-right"><span id="Test_Automation_Using_Shift_Left_and_Shift_Right"><strong><strong>Test Automation Using Shift Left and Shift Right.</strong></strong></span></h2>



<p><strong>U</strong>se of test automation when you shift your testing left, or right depends on the state of your application and the state of your testing. When shifting your testing left, <a href="https://testsigma.com/automated-testing" target="_blank" rel="noreferrer noopener">test automation</a> would help if you have tests executed repeatedly or very complex tests that would give better results upon automation. The same applies to shifting your testing right. Automating your tests for shift right makes better sense as, at this time, the application is fully developed and is expected to be more stable.</p>



<p>Let&#8217;s discuss the tools that can be used for automating your shift left tests and shift right tests.</p>



<h2 id="why-shift-right-and-shift-left-testing-are-critical-for-microservices-architecture"><span id="Why_Shift_Right_and_Shift_Left_Testing_are_Critical_for_Microservices_Architecture"><strong>Why Shift Right and Shift Left Testing are Critical for Microservices Architecture?</strong></span></h2>



<p>Both shift-left and shift-right testing are cornerstones for microservices architecture. This is because&nbsp;</p>



<ul><li>they ensure early identification of issues through detection mechanisms, </li><li>enhance collaboration between teams, </li><li>improve quality and reliability, </li><li>reduce costs through automation and </li><li>improved processes.</li></ul>



<p>Shift-Left Testing moves the testing activities earlier in the development lifecycle. Testing happens at the beginning of the process. It is like checking whether the car engine works before starting to drive.</p>



<p>Shift Right Testing moves its activities to be performed in a production-like environment. It entails monitoring how the application performs and behaves in terms of action.</p>



<p>It means testing does not stop when the car hits the road; it continues to ensure that everything is running smoothly.</p>

<p>Alright, we&#8217;re all pondering whether to go left or right. Here are some tips to help you pick the one that&#8217;s right for you. It depends on the scale of the test and the specific needs and preferences of the organization. If you want to focus primarily on the early detection of critical bugs or other software development problems, then &#8220;Shift-Left&#8221; testing is your best choice; by performing tests earlier on in the development cycle, you can detect and eliminate problems more quickly and this can save money and other resources in the long term. </p>



<p>On the other hand, if you are more concerned with verifying the correctness of the application as it is being deployed, then a &#8220;Shift-Right&#8221; approach would be more appropriate; by postponing tests to later stages of the deployment pipeline, you can ensure that features and behaviors are sufficiently tested in the environments where they are being used. In some cases, it may be beneficial to use a combination of both approaches; the key is understanding your particular needs and objectives and selecting and refining your testing strategies accordingly.</p>



<h2 id="h-conclusion"><span id="Conclusion"><strong>Conclusion</strong></span></h2>



<p>So here&#8217;s the deal &#8211; there are two operations before you: shift left and shift right. Each has its pros and cons. Shift Left is about catching defects early in the development process, while Shift Right focuses on testing in production to ensure your app works well in the real world. It really depends on what your organization needs and wants. You must consider your company culture, development processes, and business goals to determine your best approach.</p>

<h2 id="h-what-is-peer-testing"><span id="What_is_Peer_Testing">What is Peer Testing?</span></h2>



<p>Peer testing is a software development practice that developers follow to review or evaluate each other’s code. The process involves a coder checking the program of their fellow colleagues to provide feedback, identify issues, and ensure complete code quality.</p>



<p>The purpose of peer testing is to nurture a collaborative environment that leads to building bug-free applications with shared responsibility. By involving multiple developers in the review process, you can catch potential issues and promote collaboration and knowledge sharing within the development team.</p>



<p>Another approach to peer testing is testers checking the test scripts of their fellow QA engineers to see if there are any problems with the tests. It includes testers verifying the manual or automation tests of their colleagues to provide feedback and suggestions.</p>



<h2 id="h-what-are-the-benefits-of-peer-testing"><span id="What_are_the_Benefits_of_Peer_Testing">What are the Benefits of Peer Testing?</span></h2>



<p>Peer testing offers multiple benefits to the developers as well as testers involved in the project. It ensures that coders improve on their existing program and that the stakeholders receive a better-quality product to take to market. Here are some of the reasons why you should do peer testing:</p>



<ul><li><strong>Defect Identification:</strong> Peer testing helps identify defects and issues early in the development lifecycle. When team members review the code, documentation, or test scripts they can spot errors, bugs, and potential problems that may have been overlooked by the author. Finding and fixing issues early saves time and effort that would otherwise be spent on detecting and resolving defects at later stages.</li><li><strong>Quality Improvement:</strong> Peer testing contributes to improving the overall quality of the software. Through collaborative review and feedback, team members can suggest enhancements, highlight areas for improvement, and share best practices in the code or <a href="https://en.wikipedia.org/wiki/Test_script" target="_blank" rel="noreferrer noopener">test scripts</a>. This leads to better code and script readability and maintainability, resulting in higher-quality software.</li><li><strong>Knowledge Sharing and Learning:</strong> This process fosters an environment of knowledge sharing and learning within the team. Reviewing each other&#8217;s work allows colleagues to gain exposure to different coding styles, approaches, and problem-solving techniques. Testers can offer improvement in test scripts and testing approaches, learn from each other&#8217;s experiences, expand their knowledge and improve their skills.</li><li><strong>Code Consistency and Standards:</strong> Peer testing helps enforce coding standards and maintain code consistency across the project. Reviewing application code or testing scripts, ensures that developers and testers follow established guidelines, conventions, and architectural principles. Such practice makes the code and the script more readable, understandable, and maintainable, especially when multiple individuals work on the same project.</li><li><strong>Collaboration and Team Building:</strong> It promotes collaboration and team building by involving team members in the review process. It creates a sense of shared responsibility, encourages open communication, constructive feedback, and fosters a culture of continuous improvement.</li><li><strong>Risk Mitigation:</strong> Peer testing helps mitigate risks associated with software defects. Catching and addressing issues reduces the likelihood of critical bugs or functional gaps in the final product. This process improves customer satisfaction, reduces support requests, and minimizes the impact of potential issues on the project timeline.</li></ul>



<h2 id="h-who-should-do-it"><span id="Who_Should_Do_It">Who Should Do It?</span></h2>



<p>It is a very important practice that benefits the author and the reviewer. Here are some of the individuals who should be a part of the review:</p>



<ul><li><strong>Developers:</strong> Peers within the <a href="https://youteam.io/blog/guide-to-hiring-remote-team-of-software-developers/" target="_blank" rel="noreferrer noopener">development team</a> can review each other&#8217;s code to identify issues in the code, bugs, or areas for improvement.</li><li><strong>Testers:</strong> Quality assurance professionals can engage in peer testing to validate test cases, review test plans, and provide feedback on the testing process. They can check the requirement documents, the testing approach, and the use of automation tools.</li></ul>



<p>There are many other individuals involved in peer testing, such as designers, business analysts, project managers, and stakeholders, that ensure reviewing of several documents. But mostly, when it comes to checking the code or test scripts, developers and testers remain a big part of peer testing.</p>



<h2 id="h-what-are-the-requirements-of-peer-testing"><span id="What_are_the_Requirements_of_Peer_Testing">What are the Requirements of Peer Testing?</span></h2>



<p>Peer testing does not have a long list of requirements that you need to follow necessarily, but below are a few suggestions you can take into account:</p>



<ul><li>Be constructive and positive in your feedback.</li><li>Do not treat it as a formality or back away from it.</li><li>Learn from the review and the suggestions for existing and future changes in your code or test scripts.</li><li>Ask relevant questions if any doubts persist.</li><li>Follow a structured review process to avoid communication gaps or confusion about the project.</li><li>Define clear objectives of peer testing before starting the process.</li><li>Be confident that getting your work reviewed or reviewing somebody else’s code will only improve your skills and expertise.</li></ul>



<h2 id="h-how-to-perform-peer-testing"><span id="How_to_Perform_Peer_Testing">How to Perform Peer Testing?</span></h2>



<p>Upon deploying the code in the development/<a href="https://testsigma.com/blog/test-environment/" target="_blank" rel="noreferrer noopener">test environment</a>, follow the below steps to perform a standardized peer testing process:</p>



<ul><li>The coder or the tester works on their project; they design, develop, test, and implement the code or the test script.</li><li>Subsequently, they execute a self-review process. Developers perform unit testing, and testers check their scripts manually or using automated tools.</li><li>Peer testing comes now; another developer or tester checks your code and provides feedback on the same.</li><li>If there is any issue, the code or the script is Rejected and sent back to the author with suggestions. After the problem is resolved, peer testing is done again, and the function is Passed.</li></ul>



<p>You can perform peer testing in two ways: Manual or automated. Let’s discuss this.</p>



<h3 id="h-manual"><span id="Manual">Manual</span></h3>



<p>With manual peer testing, the reviewer goes through the code or the test script line-by-line manually without using any automation tools. They spend time understanding every function and looking at minute details in the program to avoid overseeing any issues. It further extends the process as the reviewer would need to carefully draft a feedback document with all the details to highlight the code&#8217;s issues and possible improvement areas.</p>



<p>While manual peer testing brings a human approach to the entire process, it is also time-consuming and prone to errors.</p>



<h3 id="h-automated"><span id="Automated">Automated</span></h3>



<p>Automated peer testing involves using an automation tool, such as Testsigma, to review and provide feedback to the author. By using an automated tool, you are saving time and resources by a tremendous amount. Tools like Testsigma offer an in-built review workflow that allows testers to verify each other’s work. </p>



<p><p style="padding-bottom:15px">It supports parallel testing and has the maintainability testing feature to continue changing the code as per the review feedback without worrying about the test cases failing. And Testsigma consists of many other functions you can employ as a tester to increase the business ROI by building end-to-end tests 10x faster for web, mobile apps, and APIs.</p></p>

<h2 id="h-disadvantages-of-peer-testing"><span id="Disadvantages_of_Peer_Testing">Disadvantages of Peer Testing</span></h2>



<p>Some of the disadvantages of peer testing are:</p>



<ul><li>A lack of expertise or skill in reviewing code as per the specified guidelines can impact the entire process.</li><li>Engaging more than one peer to perform the review in order to stay in line with the deadline can hamper communication.</li><li>Often, group dynamics and interpersonal relations also play a major role in the peer testing process, likely affecting the project’s health.</li><li>Peer testing may not provide comprehensive coverage of all aspects of the work being reviewed.</li><li>There are chances that peers engaged in the testing process may not have received formal training in review techniques or quality assurance methodologies.</li></ul>



<h2 id="h-summary"><span id="Summary">Summary</span></h2>



<p>Peer testing is verifying the code or test scripts of your fellow colleagues to offer constructive advice on improving the program or test script and making it better. With multiple advantages and disadvantages to the process, peer testing is still a good practice to follow as it allows both the author and the tester to work on their skills and improve communication across the team.</p>
