<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>

<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>

What Is an Edge Case Testing? How To Find and Prioritize


<p>When it comes to ensuring the quality of software, testing is essential. The testing process can vary depending on the application type being developed and its purpose. One form of testing used in software development is known as screenshot Testing, also sometimes known as <a href="https://testsigma.com/guides/visual-testing/" target="_blank" rel="noreferrer noopener">Visual Testing</a>. </p>



<p>Screenshot testing is a term used for testing that involves taking a screenshot of the application&#8217;s user interface (UI). By taking screenshots of different software versions, and comparing them, it becomes easy to identify the visual changes and determine whether they are fair. </p>



<p>This guide discusses screenshot testing, how it works, and how to perform the process on different platforms.</p>

<h2 id="h-what-is-screenshot-testing"><span id="What_is_Screenshot_Testing"><strong>What is Screenshot Testing?</strong></span></h2>



<p>In Screenshot testing, testers take screenshots of the application or website under test and compare them to the expected results. They can then identify discrepancies between the two and report them to developers for resolution. This process helps ensure the application or website meets design specifications and provides a positive user experience.</p>



<p>This testing is particularly useful when the UI of the application gets changed often and can point out the smallest of differences from the expected results very quickly.</p>



<h2 id="h-how-does-screenshot-testing-work"><span id="How_Does_Screenshot_Testing_Work"><strong>How Does Screenshot Testing Work?</strong></span></h2>



<p>You take screenshots of the website or app in different environments like browsers, resolutions, and operating systems. Following these steps ensures that your website or application functions optimally and provides a positive user experience.</p>



<p><strong>Here are the steps:</strong></p>



<p>Step 1: Choose a Screenshot Testing Tool</p>



<p>The first step is to choose a Screenshot testing tool that suits your needs. Many options are available in the market, such as Testsigma, Applitools, Percy, and Cypress. Each tool has its unique features and benefits.</p>



<p>Step 2: Define Test Scenarios </p>



<p>Once you have selected a tool, the next step is to define test scenarios. This involves identifying your application&#8217;s different pages or screens that need to be tested. You can also define specific actions that users might take on these pages.</p>



<p>Step 3: Capture Screenshots</p>



<p>After defining test scenarios, you must capture screenshots of each page or screen using the screenshot testing tool. This can be done manually or automatically, depending on your tool. These screenshots become the baseline for your screenshot tests.</p>



<p>Step 4: Compare Screenshots</p>



<p>Once you have captured the screenshots, the next step is to compare them. By comparing the screenshots, you can ensure that the UI is consistent with the expectation. This will help you identify any visual bugs or inconsistencies that may have been introduced during development or changes made to the page. </p>



<p>Step 5: Resolving the Issue</p>



<p>After identifying any visual bugs or inconsistencies, addressing them promptly is important. This may involve making changes to the code or design of the page. Once the necessary adjustments have been made, repeating the comparison process is recommended to ensure the issues have been resolved. Tools like Testsigma, Applitools, Percy, and BrowserStack can automate this process and make it way faster to compare multiple screenshots simultaneously. </p>

<h3 id="h-agile-overview"><span id="Agile_Overview"><strong>Agile Overview</strong></span></h3>



<p>Agile project management methodology emphasizes flexibility, collaboration, and rapid iteration. Many industries have adopted it since it was originally developed for software development projects. One of the key principles of Agile is the prioritization of customer satisfaction through the continuous delivery of valuable products or services. To achieve this, the development team collaborates closely with stakeholders, including customers and end-users.</p>



<p>Agile values individuals and interactions over processes and tools, highly emphasizing communication and teamwork. This approach allows for quick adaptation to changing requirements or market conditions.</p>



<p>Another important aspect of Agile is its iterative approach to development. Rather than completing a project in one large phase, Agile breaks it down into smaller, more manageable pieces called sprints. After each sprint, the team produces a working product or feature, which can be tested and evaluated before moving on to the next sprint.</p>



<p>Overall, Agile offers a flexible and collaborative approach to project management that prioritizes customer satisfaction, teamwork, and adaptability.</p>



<h2 id="h-how-do-devops-and-agile-interrelate-with-each-other"><span id="How_do_DevOps_and_Agile_Interrelate_with_each_other"><strong>How do DevOps and Agile Interrelate with each other?</strong></span></h2>

<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>



<p>More details are in the table below:</p>



<h2 id="h-monkey-testing-vs-gorilla-testing-a-comparison"><span id="Monkey_Testing_vs_Gorilla_Testing_A_Comparison"><strong>Monkey Testing vs. Gorilla Testing: A Comparison</strong></span></h2>



<figure class="wp-block-table"><table><tbody><tr><td><strong>Monkey Testing</strong></td><td><strong>Gorilla Testing</strong></td></tr><tr><td>It is a type of testing that doesn&#8217;t require planning or knowledge of the system being tested.</td><td>Requires some basic prior knowledge of the system being tested and a test plan.</td></tr><tr><td>It is a software testing method that does not follow a defined test plan and instead relies on testers to try out the application randomly.&nbsp;</td><td>Its name implies it is a more intensive form of testing that involves longer and more resilient test cycles.

<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>

Gorilla Testing How It Is Different from Monkey Testing

Gorilla Testing: How It Is Different from Monkey Testing


<p>In simple terms, shift left refers to moving testing and quality assurance earlier in the development process, while shift right focuses on testing and monitoring after the software is released. In this blog post, we&#8217;ll break down the differences between Shift Left vs Shift Right and why they matter.</p>

<h2 id="h-what-is-the-difference-between-shift-left-and-shift-right"><span id="What_is_the_Difference_Between_Shift_Left_and_Shift_Right"><strong>What is the Difference Between Shift Left and Shift Right?</strong></span></h2>



<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>



<h2 id="shift-left-vs-shift-right-when-to-use-which"><span id="Shift_Left_vs_Shift_Right_When_to_Use_Which"><strong>Shift Left vs Shift Right: When to Use Which?</strong></span></h2>



<p><strong>Shift Left</strong> is ideal for identifying and acting on issues early in the software development lifecycle, during requirements gathering and early testing. It is best suited for projects that emphasize quality and rapid iteration.</p>



<p><strong>Shift Right </strong>is all about making sure your app performs well, keeping an eye on how it&#8217;s doing, and making sure users are happy once it&#8217;s out there. It&#8217;s great for apps that need constant tweaks. Also, for real-time feedback to make sure they work well and keep users happy.</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>

<p>Shift Left Testing: This testing operation occurs early in the software development life cycle. An example of this could involve unit and integration testing performed by developers and QA specialists before handing off the project to operations or the customer. Shift right testing is a testing approach that moves testing activities to the right of the development cycle, meaning it starts later in the process. An example would be having the customer perform user acceptance testing at the end of the development cycle to ensure the product meets their needs and requirements.</p>

<p>Testing levels, also known as levels of testing, refer to the different phases or stages of testing software during its development cycle. The main idea behind this concept is that each level of testing targets specific aspects of the software&#8217;s functionality, which allows for better quality assurance and fewer potential defects.</p>



<p>The most common <a href="https://testsigma.com/blog/the-different-software-testing-types-explained/" target="_blank" rel="noreferrer noopener">types of testing</a> levels include &#8211; unit testing, integration testing, system testing, and acceptance testing. Unit tests focus on individual components, such as methods and functions, while integration tests check if these components work together properly. System tests verify that the entire system meets the functional requirements specified by stakeholders, while acceptance tests validate the software against their criteria for acceptable behavior.</p>



<div class="wp-block-image"><figure class="aligncenter size-full is-resized"><img loading="lazy" src="https://testsigma.com/blog/wp-content/uploads/Levels-of-testing-1.png" alt="Levels of Testing" class="wp-image-31585" width="362" height="294"/></figure></div>



<h2 id="h-what-are-the-different-levels-of-testing"><span id="What_are_the_Different_Levels_of_Testing"><strong>What are the Different Levels of Testing?</strong></span></h2>



<p>Software must go through different testing stages before it can be considered bug-free and ready for deployment. There are generally four levels of software testing, as mentioned below:</p>



<ol><li><a href="https://testsigma.com/blog/unit-testing/" target="_blank" rel="noreferrer noopener">Unit Testing</a></li><li><a href="https://testsigma.com/guides/integration-testing/" target="_blank" rel="noreferrer noopener">Integration Testing</a></li><li>System Testing</li><li>Acceptance Testing</li></ol>



<p>Let&#8217;s have a look at these in detail.</p>



<h3 id="h-1-unit-component-testing"><span id="1_UnitComponent_Testing"><strong>1. Unit/Component Testing</strong></span></h3>



<p>Unit testing is done at the code level, where each component is tested individually to ensure their impartiality and analyze their functionality. Automating <a href="https://en.wikipedia.org/wiki/Unit_testing" target="_blank" rel="noreferrer noopener">unit tests</a> is possible and highly recommended in today&#8217;s fast-paced development environment. To make a unit test, you should outline what you expect the code to do and write the code, which will check if it is doing what you expect. You should then run the unit test to verify that everything works as expected. For example, let&#8217;s say you have a calculator program that adds two numbers together. You can create a unit test that verifies the numerical values that the calculator program returns are correct. You could also create tests that verify edge cases and errors are handled correctly.</p>



<p>In this simple example, you could use unit testing to verify that the calculator program adds two numbers correctly.</p>



<p>First, outline and document the expectations of the program, such as:</p>



<ul><li>The program should accept two numerical values</li><li>It should return the sum of these two values</li><li>It should also handle negative numbers correctly</li></ul>



<p>You can then write unit tests that feed these values into the program and verify the correct output. For example, you could have a test that checks the program returns 2 when 1 and 1 are entered. You could have another test that checks the program returns -3 when 1 and -4 are entered. Once all the tests have been written and executed, you can confidently say that the calculator program has been successfully tested and works as expected.</p>



<h3 id="h-2-integration-testing"><span id="2_Integration_Testing"><strong>2. Integration Testing</strong></span></h3>



<p><a href="https://testsigma.com/guides/integration-testing/">Integration testing</a> enables software testers to test group units integrated into a system or subsystems; it helps identify any bugs or issues arising from coding errors or integrations between modules. It is possible to automate integration testing.</p>



<h3 id="h-3-system-testing"><span id="3_System_Testing"><strong>3. System Testing</strong></span></h3>



<p>System testing is performed on an integrated environment comprising the whole application, where all components are assessed against specific business requirements. You can use automation tools for System Testing.</p>



<p>For example, Testsigma, a no-code test automation platform, can complete end-to-end flows for web, mobile, and desktop applications and APIs.</p>



<h3 id="h-4-acceptance-testing"><span id="4_Acceptance_Testing"><strong>4. Acceptance Testing</strong></span></h3>



<p><p style="padding-bottom:30px">Acceptance testing involves testing the system&#8217;s <a href="https://testsigma.com/guides/functional-testing/" target="_blank" rel="noreferrer noopener">Functional </a>and Non-functional aspects, such as performance, security, usability, accessibility, compatibility, and reliability. Depending on the system&#8217;s complexity, it can be done manually or through automation tools. In this example, we will demonstrate the process of using Testsigma to automate the acceptance testing of a login page. First, we must create a test scenario that simulates users entering their login credentials and logging in successfully. Testsigma will automatically detect any issues with the page and report them back to us. Using Testsigma for acceptance testing, we can ensure that our login page is working as expected and ready for deployment.</p></p>

<h2 id="h-software-testing-sequence"><span id="Software_Testing_Sequence"><strong>Software Testing Sequence</strong></span></h2>



<p>Let&#8217;s talk about test sequences. It&#8217;s a fancy way of saying we need to test our software step by step. We must go through four main testing stages before we can say our software is ready.</p>



<ol><li>First up, we&#8217;ve got unit testing. This is where we test each unit or component of the software to ensure it&#8217;s doing what it&#8217;s supposed to.</li><li>Then we move on to integration testing, where we test how all the different units work together.</li><li>Next, we&#8217;ve got system testing, where we test the whole system as a complete package.</li><li>Finally, we&#8217;ve got acceptance testing, where we let the end users have a go at the software to ensure it&#8217;s meeting their needs.</li></ol>



<p>And that&#8217;s it! Four simple steps to make sure our software is top-notch.</p>

<p>Software Testing is a necessary process. It guarantees the software does what it should and meets all the requirements. Skipping testing can lead to severe issues that can mess up the software&#8217;s usefulness and how it works. So, don&#8217;t forget to give enough time and resources to test your software if you want it to be a hit when you launch it.</p>

Levels of Testing A Complete Approach to Quality Assurance

Levels of Testing: A Complete Approach to Quality Assurance


<p>Regression testing is a software testing process that involves verifying the functionalities of an application or system after modifications have been made that could impact its performance. Unit testing is a software testing process that involves thoroughly testing individual functions or modules of a program using specialized tools. Unit testing helps testers to catch bugs early in the development process when they can be addressed more efficiently. This blog is about Regression Test vs Unit Test.</p>



<p>We know testing has become a necessary part of the software development life cycle. With the rise of Agile and DevOps methodologies, developers must deliver software faster than ever without sacrificing quality. We must do testing more efficiently and with higher precision. Regression testing and unit testing are 2 types of testing that we talk about, in this blog. We&#8217;ll talk about their benefits, main differences, and other important stuff to help you tell them apart easily.</p>

<p>These two types of testing have different objectives. Also, they require different skills, tools, and techniques.</p>



<h3 id="h-what-is-unit-testing"><span id="What_is_Unit_Testing"><strong>What is Unit Testing?</strong></span></h3>



<p>Unit testing isn&#8217;t anything new. It&#8217;s been around since the early days of programming, you know. Testers use unit testing to test individual pieces of code or &#8220;units&#8221; and ensure they function as expected. This approach helps catch errors or bugs early in development, making fixing them easier and less costly.<em>One example of unit testing is testing a function that calculates the sum of two numbers. The test would involve providing two numbers as input and verifying that the output is the correct sum of those numbers. </em>For example, if the input numbers are 4 and 6, the output should be 10. This testing approach helps ensure that each unit works as intended and can be integrated into a larger system without issues.</p>



<h3 id="h-what-is-regression-testing"><span id="What_is_Regression_Testing"><strong>What is Regression Testing?</strong></span></h3>



<p><a href="https://testsigma.com/regression-testing" target="_blank" rel="noreferrer noopener">Regression testing</a> is a software testing process that involves verifying the functionalities of an application or system after modifications have been made that could potentially impact its performance. We do this to ensure that the modifications or updates have not broken any existing functionality and to confirm that there are no unexpected side effects.</p>



<p>You can conduct regression testing manually or through automation tools. Regression testing plays an essential role in the software development life cycle since developers continuously make new modifications to an application&#8217;s codebase.</p>



<p>For example, a web application has significantly updated its user interface. The testing team would need to verify that all previously functional features, like the home page, login page, cart, checkout, payment etc, still perform as expected and that the new user interface does not introduce any defects. By conducting thorough regression testing, software developers can ensure that their products continue to meet the high standards of quality and functionality that users expect.</p>



<h2 id="h-when-and-why-do-you-need-both-testing-types"><span id="When_and_Why_Do_You_Need_Both_Testing_Types"><strong>When and Why Do You Need Both Testing Types?</strong></span></h2>



<p>Regression Testing and Unit Testing are two important types of software testing. Regression testing is necessary when changes are made in the code base, which might affect other software parts. Unit Tests are essential because they help identify any issues with the functions individually before being integrated into the final product. Below are some reasons why you need regression testing and unit testing:</p>



<p><strong>When do you need regression testing?</strong></p>



<ul><li>Regression testing is testing that makes sure changes or updates to a software system don&#8217;t cause any unintended effects or break anything that used to work.</li><li>You&#8217;ll generally want to do this testing whenever you make any changes, add new features, or bring in new data.</li></ul>



<p><strong>Why do you need unit testing types?</strong></p>



<ul><li>To identify any problems with specific code units at an early stage.</li><li>Help troubleshoot complicated systems by isolating individual components.</li><li>To make it easier to extend, modify, and refactor code over time without breaking anything.</li></ul>



<h3 id="h-unit-tests-vs-regression-tests-the-differences"><span id="Unit_tests_vs_Regression_tests_the_differences"><strong>Unit tests vs. Regression tests – the differences</strong></span></h3>



<p>Okay, let&#8217;s break it down! The below table gives you the major differences between these tests.</p>

<h2 id="h-6-key-phases-of-testing"><span id="6_Key_Phases_of_Testing"><strong>6 Key Phases of Testing </strong></span></h2>



<p>Here are the phases of software testing explained in detail.</p>



<h3 id="h-1-requirement-analysis"><span id="1_Requirement_analysis"><strong>1. Requirement analysis</strong></span></h3>



<p>Requirement analysis involves identifying, analyzing, and documenting the requirements of a software system.</p>



<ul><li>During requirement analysis, the software testing team works closely with the stakeholders to gather information about the system&#8217;s functionality, performance, and usability.</li><li>The requirements document serves as a blueprint for the software development team, guiding them in creating the software system.</li><li>It also serves as a reference point for the testing team, helping them design and execute effective test cases to ensure the software meets the requirements.</li></ul>



<p>In summary, by conducting thorough requirement analysis, software testing teams can help ensure the software system&#8217;s success and user satisfaction.</p>



<h3 id="h-2-test-planning"><span id="2_Test_planning"><strong>2. Test planning</strong></span></h3>



<p>During the test planning phase, the team develops a complete plan outlining each testing process step, including identifying requirements, determining the target audience, selecting appropriate testing tools and methods, defining roles and responsibilities, and defining timelines. This phase aims to ensure that all necessary resources are in place and everyone on the team understands their roles and responsibilities. A well-designed test plan minimizes risks by ensuring that potential defects are identified early in the development cycle when they are easier to fix. Also, adhering to the plan throughout the testing process fosters thoroughness and consistency in testing efforts which can save time and cost down the line.</p>



<h3 id="h-3-test-case-development"><span id="3_Test_case_development"><strong>3. Test case development</strong></span></h3>



<p>During the test case development phase, the team thoroughly tests the software and considers all possible scenarios.</p>



<p>This phase involves multiple steps, including test design, test case creation, and test case review:</p>



<ul><li>Test design involves identifying the test scenarios and defining the steps to be followed during testing.</li><li>Writing test cases for each identified scenario, including input data, expected output, and the steps to be followed, involves creating test cases.</li><li>Test case review involves reviewing the test cases to ensure they are complete and cover all possible scenarios.</li></ul>



<p>Also, this is the phase when the involvement of test automation can be started. You can select the test cases for test automation here. And, if automation is already a part of the STLC, and the product is suitable for testing, then the test case automation can be started too.</p>



<h3 id="h-4-test-environment-setup"><span id="4_Test_environment_setup"><strong>4. Test environment setup</strong></span></h3>



<p><a href="https://testsigma.com/blog/test-environment/" target="_blank" rel="noreferrer noopener">Test environment</a> setup in software testing life refers to creating an environment that simulates the production system where the software application is deployed. A person can ensure efficient and effective testing activities by designing the test environment correctly.</p>



<p>The setup includes</p>



<ul><li>hardware,</li><li>software,</li><li>networks, and</li><li>databases.</li></ul>



<p>When setting up test environments, we consider network bandwidth, server capabilities, and storage capacity. A properly set-up test environment aims to replicate real-world scenarios to identify potential issues before deployment in production systems. Testers can perform functional, performance, or load testing during this phase. Automating your Test environment setup can make your work easier. You can set up automated tests to run on the configured setups here.</p>



<h3 id="h-5-test-execution"><span id="5_Test_execution"><strong>5. Test execution</strong></span></h3>



<p>Test execution refers to the software testing life cycle phase where created test cases are executed on the actual system being tested. At this stage, testers verify whether features, functions, and requirements prescribed in earlier phases perform as expected. The test execution also involves the execution of automated test cases.</p>



<h3 id="h-6-test-closure"><span id="6_Test_closure"><strong>6. Test closure</strong></span></h3>



<p>Test closure is integral to the STLC and includes completing all planned testing activities. It includes</p>



<ul><li>reviewing and analyzing test results,</li><li>reporting defects,</li><li>identifying achieved or failed test objectives,</li><li>assessing test coverage, and</li><li>evaluating exit criteria.</li></ul>



<p>For example, in agile methodology, test closure occurs at the end of each sprint as a formal review meeting with essential stakeholders. The team aims to validate that they have adequately tested all the functionality before release. They generate closure reports detailing the overall product quality and bug statistics, leading to the project&#8217;s successful conclusion.</p>



<p>Effective test closure signifies that the software product is ready for delivery and can move towards launch after addressing all identified defects and weaknesses, ensuring flawless functioning and a positive user experience.</p>



<p>When discussing test automation, the effective generation of test reports and integration with other tools in the test process also plays a big role.</p>
