DevOps life cycle Phases Explained with Example

What is DevOps Life Cycle | Key Components & Phases with Examples?


<p>Reviewing your work is critical in the software development life cycle (SDLC). It reduces the instances of human errors and allows for better-quality code. Similarly, peer review in important, that involves peers checking each other’s work. But why is it essential, and how much software quality does it improve? Let’s see.</p>

<h2 id="h-what-is-peer-review-in-software-testing"><span id="What_is_Peer_Review_in_Software_Testing">What is Peer Review in Software Testing?</span></h2>



<p>Peer review in software testing can be described in 2 ways:</p>



<p> 1. A practice of checking or reviewing the code of your fellow developer.</p>



<p> 2. It can also mean checking the test cases and scripts created by your fellow testers to provide feedback and reduce testing issues.</p>



<p>Peer reviews involve viewing and testing the functioning some code or test cases to ensure that they meets the essential requirements criteria. The aim of peer review is to highlight any possible issues the piece being reviewed, suggest improvements, and check if their compliance with standards. Peer reviews help in getting a different perspective on one’s work and receiving suggestions on making the work not only better but also easier to follow. Peer review can be considered a static testing technique.</p>



<p>There are automated tools too that support the review of <a href="https://testsigma.com/automated-testing" target="_blank" rel="noreferrer noopener">automated tests </a>like <a href="https://testsigma.com/mobile-testing-tools" target="_blank" rel="noreferrer noopener">Testsigma,</a> that is built with review workflows, enabling testers to review each other’s work.

<br><h2 id="h-why-do-we-need-peer-review"><span id="Why_Do_We_Need_Peer_Review">Why Do We Need Peer Review?</span></h2>



<p>There are many reasons why you need to adopt peer review practice in your SDLC process. And it’s more than just improving the code quality.</p>



<ul><li>The inquisitive approach of your fellow developers and testers is sure to find minute issues that might miss your eyes.</li><li>It improves communication and accessibility within the team, as everyone knows who is working on what. This kind of understanding will increase the give-and-take of information among the team members.</li><li>Peer review facilitates learning among peers and builds an environment of healthy competition.</li><li>This process helps save costs in outsourcing the reviewing task to external resources or buying tools for the exact purpose.</li><li>Peer review practice is important as it also helps developers and testers meet their deadlines by taking help from their fellow team mates to solve any blockers faced.</li></ul>



<h2 id="h-what-should-we-review"><span id="What_Should_We_Review">What Should We Review?</span></h2>



<p>There is no point in promoting peer review when you don’t know what things you should review in the first place. There is a plethora of documentation to prove that soliciting feedback results in improving the quality of the product and reducing rework. We have a list of all the necessary documents and tasks you should include in your peer review process:</p>



<ul><li>Product definition and marketing planning document to properly analyze the product’s purpose and delivery needs</li><li>User requirements/specifications documents containing all the information end-users want in the application</li><li>System design documents that consist of system architecture and UI/UX plan</li><li>Programming code reviewing involves checking the backend code and looking for defects, improvements, and flow</li><li>Test plans and test cases documents consist of the test scenario, steps, and more</li></ul>



<p></p>



<h2 id="h-types-of-peer-reviews"><span id="Types_of_Peer_Reviews">Types of Peer Reviews</span></h2>



<p>Peer review in software testing can be classified into two types: formal and informal. They differ in how they are conducted within the organization.</p>



<h3 id="h-formal"><span id="Formal">Formal</span></h3>



<p>A formal peer review is one which is led by a trained moderator and follows a particular structure. It consists of a series of tasks, including requirements walkthroughs, technical reviews, inspections, and a well-detailed report at the end.</p>



<h3 id="h-informal"><span id="Informal">Informal</span></h3>



<p>Informal peer review is the exact opposite of formal. No moderator leads the process, and it is usually a personal favor that your colleagues ask of you. It follows no structure, and there are no recorded minutes of meetings for reviewers to access.</p>



<h2 id="h-peer-review-process"><span id="Peer_Review_Process">Peer Review Process</span></h2>



<p>Follow these different ways to implement a peer review process in your company:</p>



<p><strong>Informal:</strong> Start with the informal review process that simply consists of asking a fellow developer or tester to check your code or tests for correctness and to suggest improvements.</p>



<p><strong>Walkthrough:</strong> This method consists of a software developer or tester leading peers interested in the review process. They can pose questions while reviewing and come up with their explanation/understanding of the product.</p>



<p><strong>Create a structure:</strong> For a formal review process, creating a structure and having a moderator enforce the structure upon the reviewers is the best way to go.</p>



<p><strong>Review:</strong> Start the review process formally or informally, as mentioned in the above steps.</p>



<p><strong>Verify:</strong> Verification involves an organized way of conducting the evaluation process. It involves applying several testing metrics/techniques to understand the results of the review process and to analyze the validity of the output.</p>



<h2 id="h-peer-review-static-testing"><span id="Peer_Review_8211_Static_Testing">Peer Review &#8211; Static Testing</span></h2>



<p>Peer review is a static black-box testing technique. Static testing refers to analyzing the code and the related documents without the need to execute the program and tasks. So, instead of running the tests and uncovering defects, peer review follows the static testing method, which identifies issues before executing the code.</p>



<p>Here are some examples of what undergoes testing/analysis as a part of the static testing method:</p>



<ul><li>Requirement specification documents</li><li>Design documents</li><li>Webpage content</li><li>Source code</li><li>Test plans, test cases, test scripts, and test data</li><li>User requirement documents</li></ul>



<div class="wp-block-image"><figure class="aligncenter size-full is-resized"><img loading="lazy" src="https://testsigma.com/blog/wp-content/uploads/Frame-48095885.png" alt="Testsigma - Peer Review – Static Testing" class="wp-image-30350" width="600" height="400"/></figure></div>



<p><p style="padding-top:30px">In the above image, you can see how the peer review process gradually becomes formal as it moves down across the pyramid. The picture illustrates the different stages of the peer review process that we have discussed in the above section.</p></p>



<p>Read here about <a href="https://testsigma.com/blog/peer-testing/" target="_blank" rel="noreferrer noopener">Peer Testing</a></p>



<h2 id="h-peer-review-characteristics"><span id="Peer_Review_Characteristics">Peer Review Characteristics</span></h2>



<p>The characteristics of peer review are as below:</p>



<ul><li>It is a documented way of evaluating the code that involves a defect detection process.</li><li>The higher management is not involved in peer review. It consists of peers and a few technical specialists.</li><li>The peer review team is managed by a moderator who is not the original author of the code.</li><li>Reviewers create a final report of the review, which lists and details all the issues that require attention and enhancement in the program.</li></ul>



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



<p>Peer review is a way of checking and validating the code of another developer. It is done to offer advice on making the product better and finding bugs in the code. There are different ways to perform peer review, and the most suitable one is the formal review. We have discussed the types, benefits, and processes of peer review in software testing in the above sections.</p>



<p>Peer review is a fairly easy task that takes less time than sourcing the work to outside parties, but it offers immense advantages to the business. It builds communication among the team members and creates a sense of shared responsibilities among them. And with the right approach and moderator, any peer review will only provide positive results for every code you check.</p>



<h2 id="h-frequently-asked-questions-faqs"><span id="Frequently_Asked_Questions_FAQs">Frequently Asked Questions (FAQs)</span></h2>



<h3 id="h-what-are-the-3-kinds-of-peer-review"><span id="What_are_the_3_kinds_of_peer_review">What are the 3 kinds of peer review?</span></h3>



<p>The three kinds of peer review in testing are single-anonymized, double-anonymized, and open peer review.</p>



<p>The single-anonymized peer review is where the author does not know the identity of the reviewer. In double-anonymized, both reviewer and author don’t know the identity of each other. In Open peer review, the identity of the author and reviewer are known by everyone in the reviewing team before, during, and after the peer review process.</p>



<h3 id="h-what-is-a-peer-review-example"><span id="What_is_a_peer_review_example">What is a peer review example?</span></h3>



<p>An example of peer review is deciphering the code of a developer. Suppose your colleague approached you to see their code and check if there is any possibility of making the program easy to understand and ensuring there is a smooth flow of data between the different modules/components of the code. This is a scenario where you are the reviewer, and your colleague is the author. Another example of peer review would be verifying the project specifications and design documents after receiving them from the clients and the stakeholders before moving ahead with the project.</p>



<h3 id="h-what-are-the-5-key-elements-of-peer-review"><span id="What_are_the_5_key_elements_of_peer_review">What are the 5 key elements of peer review?</span></h3>



<p>The five key elements of peer reviews are:</p>



<ul><li>Fairness in analyzing the code/documents</li><li>Appropriately selecting the right reviewers with the relevant experience</li><li>Choosing identifiable and publicly acceptable reviewers</li><li>Timely reporting of the review results</li><li>Providing helpful feedback</li></ul>


What is Peer Review in Software Testing?


<p>All software undergoes continuous modifications. Sometimes developers do so to fulfill clients’ requests, and other times it is to upgrade the functionality or security features. But whatever the case, any changes made to the software require continuous monitoring and maintenance. Testing software for how maintainable it is, is called Maintainability testing. </p>



<p>Let’s dive deeper into the subject in this blog. We will also talk about <a href="https://testsigma.com/automated-testing" target="_blank" rel="noreferrer noopener">automated testing </a>with maintainability testing.</p>

<h2 id="h-what-is-maintainability-testing-in-software"><span id="What_is_Maintainability_Testing_in_Software">What is Maintainability Testing in Software?</span></h2>



<p>Maintainability testing is verifying the software’s ability to maintain itself as it goes through several changes. Maintainability refers to a software’s capability to maintain itself under varying situations. It is important as applications go through several changes throughout the SDLC process, which clearly requires proper maintenance along with regular testing. And with maintainability testing, it becomes easier to validate a system’s potential to keep going with frequent features updates and bug fixes, among other things.</p>



<p>Maintainability testing is non-functional testing that defines how easy it is for developers to maintain, analyze, change a system, and run tests on it.</p>



<p>Please note that <a href="https://testsigma.com/blog/test-maintenance/" target="_blank" rel="noreferrer noopener">maintenance testing</a> and maintainability testing are different. The former focuses on testing an application because of changes introduced in it. The latter checks how well the system can handle and maintain the changes.</p>



<h2 id="h-factors-affecting-the-maintainability-of-the-software"><span id="Factors_Affecting_the_Maintainability_of_the_Software">Factors Affecting the Maintainability of the Software</span></h2>



<p>There are several real-world and software-based factors that influence the maintainability of a system. </p>



<p><strong>For instance, some of the real-world factors are:</strong></p>



<ul><li>How old the software is currently and how many changes it experiences on a weekly/monthly basis?</li><li>If the memory and storage of the application is sufficient to withstand the changes and maintain its functioning accordingly.</li><li>The skill your business possesses to understand maintainability testing.</li><li>How developers built the application? Did they develop with the idea of making the system self-sufficient and maintaining itself during modifications?</li></ul>



<p><strong>The software-based factors are:</strong></p>



<ul><li>Does the structure of the software support maintenance?</li><li>Which programming language is used to develop the software?</li><li>If the software is self-reliable to withstand changes without breaking down.</li></ul>



<h2 id="h-how-to-measure-the-maintainability-of-an-application"><span id="How_to_Measure_the_Maintainability_of_an_Application">How to Measure the Maintainability of an Application?</span></h2>



<p>Now, we will discuss how to measure them and gauge the maintainability of an application. Two of the most common measurement scales are: how changeable an application is and how stable it is while going through those changes. <a href="https://www.iso.org/home.html" target="_blank" rel="noreferrer noopener nofollow">ISO</a> is a popular standard that is internationally accepted and also provides guidelines for Systems and Software Quality Requirements and Evaluation (SQuaRE).</p>



<p>There are 5 prominent ISO-defined attributes that support the measurement of an application’s maintainability:</p>



<ul><li><strong>Modularity:</strong> This attribute focuses on the modular components of the system. It checks if the software consists of several independent components coming together. Based on the modularity of the application, a small change can have an impact on the application that might require renovations.</li><li><strong>Reusability:</strong> This attribute looks for pre-existing code snippets you can reuse in the application or another software to replicate its functionality. It reduces the cost of writing new code and improves the quality and overall productivity of the software.</li><li><strong>Analyzability:</strong> It checks how efficiently a software flow, often unintended, can be found and fixed. This attribute identifies defects in the system components that require changing.</li><li><strong>Modifiability:</strong> As per its name, modifiability is the criteria of the system that checks how much a system can be modified without compromising its quality and existing features.</li><li><strong>Testability:</strong> This attribute defines the degree of effectiveness with which test criteria can be developed. It further checks if these tests can meet those criteria.</li></ul>



<h2 id="h-how-to-improve-your-software-maintainability-with-testsigma"><span id="How_to_Improve_Your_Software_Maintainability_with_Testsigma">How to Improve Your Software Maintainability with Testsigma?</span></h2>



<p>There is no one way or concrete method to follow while implementing maintainability testing. As every software undergoes certain changes throughout SDLC and even after its release, maintainability testing then works on a case-to-case basis. Typically, automation tools greatly support and expedite maintainability, such as <a href="https://testsigma.com/" target="_blank" rel="noreferrer noopener">Testsigma</a>. Let’s take an example of running visual testing with Testsigma to understand how the tool supports maintainability testing. You can perform both static and dynamic visual testing using our tool.</p>



<p>Testsigma allows the execution of visual testing for web and mobile applications. Before starting, you only need to tick the ‘Enable Visual testing for this step’ option. The visual testing option is now available for the next successful run, where the online UI elements are compared against a baseline image.</p>



<h3 id="h-steps-to-conduct-gui-testing-with-testsigma"><span id="Steps_to_conduct_GUI_testing_with_Testsigma">Steps to conduct GUI testing with Testsigma:</span></h3>



<ul><li>Create a test case, add it to a test suite, and add the test suite to a Test Plan as per your requirement.</li></ul><br>

<br><ul><li>Enable Visual Testing for the test steps that need visual testing.</li></ul><br>



<div class="wp-block-image"><figure class="aligncenter is-resized"><img loading="lazy" src="https://s3.us-east-1.amazonaws.com/blog-assets-production.testsigma.com/blogs/wp-content/uploads/migrated_images/enable-visual-testing_db8e8e08798cc94c84f275da70258acb_2000.jpg_1748948148.jpg" alt="Enable Visual Testing" width="800" height="400"/></figure></div>



<br><ul><li>Run your test plan once to save all images as base images. These are the baseline pictures to compare the visual changes.</li><li>Now Run your test plan again. The tool will automatically take screenshots of your application at every test step and make reference images.</li></ul><br>



<div class="wp-block-image"><figure class="aligncenter is-resized"><img loading="lazy" src="https://s3.us-east-1.amazonaws.com/blog-assets-production.testsigma.com/blogs/wp-content/uploads/migrated_images/run-the-test-plan-view-the-results_377cd46e65e10a74256e68a4d06ad5a6_2000.jpg_1748948146.jpg" alt="Run the Test Case" width="800" height="400"/></figure></div>



<br><ul><li>Testsigma automatically compares these reference images with the base images in the first run to find differences.</li></ul><br>



<div class="wp-block-image"><figure class="aligncenter is-resized"><img loading="lazy" src="https://s3.us-east-1.amazonaws.com/blog-assets-production.testsigma.com/blogs/wp-content/uploads/migrated_images/find-visual-errors_10baecf60cdf72d6e7323219516b3b39_2000.jpg_1748948152.jpg" alt="Compare the Results" width="800" height="400"/></figure></div>



<br><ul><li>Any other changes in the screenshots are automatically ignored to avoid false negatives.</li></ul><br>



<p>Having a baseline image makes it easy to test the visuals and maintain the same quality and look of the application in the future. Such practice improves the maintainability of the application and even allows for reusing the test cases if similar visuals need to be tested later on. <a href="https://testsigma.com/request-demo" target="_blank" rel="noreferrer noopener">Sign up for a demo</a> to see all this in action.</p>

<p>But before you start maintaining your tests and also implement maintainability testing, here are some of the best practices that work for every type/category:</p>



<ul><li>Ensure to build a list of maintainability factors before you start with the testing, which would include the stability and complexity of the code.</li><li>The software must adhere to appropriate standards for the database, interface, and development processes. One instance of this will be verifying if the application supports optimized algorithms and the ability to reuse the code.</li><li>Your maintainability testing should comply with the five maintainability attributes we mentioned above: Modularity, Reusability, Analyzability, Modifiability, and Testability.</li></ul>



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



<p>Maintainability testing is the software’s ability to maintain itself as it goes through several modifications. It reduces the cost of maintaining the system. There are different categories of maintainability testing that focus on separate areas of the application and check for possible issues.</p>



<p>There are multiple ways to measure maintainability, which we have discussed in the above section.</p>

<p>As a software project ends, every tester must check the effectiveness of the testing process to gain insights into the areas of improvement. So, QAs create a Test Closure Report. It includes all the test data, such as test cases, test plans, test suites, and other testing-related information for future reference. With this report, the test insights are recovered, making reviewing the testing process easier and identifying improvement areas in future projects. In this blog, we&#8217;ll discuss the importance of a Test Closure report in the testing development life cycle and detailed steps involved in creating a Test Closure report.</p>

<p>Test Closure is a crucial step in the TDLC that formally concludes and completes testing activities for a software release. It comprehensively summarizes the testing activities and results, including any issues and bugs found and resolved during the testing phase. Test Closure can also be considered as documentation of the testing process, and its purpose is to inform stakeholders about the quality and readiness of the software for release.</p>



<p>A good Test Closure has details such as the testing scope, <a href="https://testsigma.com/blog/test-environment/" target="_blank" rel="noreferrer noopener">test environment</a>, testing methodologies, test cases, and any issues and defects identified and resolved during testing.

Presenting test metrics to clients not only helps them understand the effectiveness of the testing process but also builds their confidence in the software.</li></ul>



<h3 id="h-stages"><span id="Stages">Stages </span></h3>



<p>Test closure is an important phase in the software development life cycle, which has six distinct stages, to ensure the quality and effectiveness of the software before we release it to the end users.</p>



<ul><li><strong>Checking planned deliverables: </strong>The first stage is to check the planned deliverables, which includes reviewing the test case documents, test plan, test scripts, test data, traceability matrix, test results, and reports. Here, the team ensures that all the planned deliverables are met and delivered to the stakeholders.</li><li><strong>Closing Incident Reports: </strong>Incidents are any variations or deviations observed during the testing phase. These incidents are logged as a report in the earlier stages and resolved before the process ends.</li><li><strong>Handover to Maintenance: </strong>After resolving incidents, the testware (all the info regarding test plans, test cases, test scripts, and other things needed to design and execute a test) is handed over to the maintenance team. They provide support to the software during its release.</li><li><strong>Archiving Environment: </strong>Here, the software, including test scripts, test environment, and test infrastructure, are finalized and archived for later use.</li><li><strong>Documenting System Acceptance: </strong>System acceptance testing is an important step in software testing since it validates that the system is ready for deployment and satisfies user expectations. By performing system acceptance testing, you can minimize the risks of deploying software lacking the desired criteria/quality. So, documenting this includes every aspect of the developed software and application and its supporting data and information. The customer representatives then accept it before the implementation of the software system.</li><li><strong>Analyzing Best Practices: </strong>The last stage involves exploring best practices. This stage is important as it helps to identify lessons learned from the project for future reference. It also helps to determine the changes required for similar projects in the future.</li></ul><br>

<br><h2 id="h-what-is-a-test-closure-report"><span id="What_is_a_Test_Closure_Report"><strong>What is a Test Closure Report?</strong></span></h2>



<p>A test closure report is a document with a summary of a project&#8217;s entire testing process and its results. The report gives insights into test executions and software performance in the tests. Anyone from the team can use this report to evaluate the quality of the software and make an informed decision on its release.</p>



<p>Once the testing is complete, the testing team prepares the test closure report. The report consists of various metrics collected during the testing process. The test closure report is prepared to include all the necessary information that can support the completion of the test execution cycle. The report must contain screenshots, query results, recordings, and log files that provide a detailed account of the testing process. The test closure report template typically includes the following sections:</p>



<ul><li><strong>Test Summary Report:</strong> A complete document overviews the testing process, activities, and results.</li><li><strong>Identifier: </strong>A unique reference number set to the test closure report for easy tracking.</li><li><strong>Test Summary: </strong>A summary highlighting the key results, accomplishments, and challenges faced during testing.</li><li><strong>Variances: </strong>Any variations during testing activities and their impact on the project.</li><li><strong>Comprehensive Assessment:</strong> A detailed evaluation (strengths/weaknesses) of the quality of the software.</li><li><strong>Summary of Results: </strong>A brief of the test results, along with the test cases executed, passed, failed, and any outstanding issues.</li><li><strong>Evaluation:</strong> A review of the overall efficiency of the testing process.</li><li><strong>Summary of Activities</strong>: A short summary of testing activities completed, such as test planning, test design, and execution.</li><li><strong>Approval:</strong> Confirmation of completion of test closure report and approval by stakeholders, such as PMs, dev teams, and QAs.</li></ul>

Test Closure Report: Everything You Need To Know


<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>

<h2 id="h-what-is-regression-testing-vs-what-is-unit-testing"><span id="What_is_Regression_Testing_vs_What_is_Unit_Testing"><strong>What is Regression Testing vs. What is Unit Testing?</strong></span></h2>



<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>



<figure class="wp-block-table"><table><tbody><tr><td><strong>Unit Test</strong></td><td><strong>Regression Test</strong></td></tr><tr><td>Unit tests are designed to test individual code units, typically at the function or method level.</td><td>Regression testing involves running a suite of tests to ensure that new code changes don&#8217;t adversely affect existing functionality in an application.

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



<p>To summarize, regression and unit tests are essential in software testing to ensure quality and prevent errors. Understanding the differences between regression and unit tests is key to implementing an effective testing strategy that improves the overall quality of the software. Yet, using both types of testing in concurrence with each other will help ensure the code is thoroughly tested. If any issues are found, they will be resolved before they can cause problems for end-users.</p>



<h2 id="h-frequently-asked-questions"><span id="Frequently_Asked_Questions"><strong>Frequently Asked Questions</strong></span></h2>



<h3 id="h-are-regression-tests-unit-tests"><span id="Are_regression_tests_unit_tests"><strong>Are regression tests unit tests?</strong></span></h3>



<p>Regression and unit tests are different. Regression tests ensure that existing functionality works correctly after new changes have been done, whereas unit tests verify that individual units of code work properly in isolation.

What is Error Guessing Technique in Software Testing

What is Error Guessing Technique in Software Testing?


<p>Software testing is an essential aspect of software development that ensures that software products are functional, reliable, and meet the required specifications. Testing is crucial to identify software errors and bugs that can lead to system failures, data loss, and other negative impacts. Boundary Value Analysis (BVA) and Equivalence Class Partitioning (ECP) are two widely used testing techniques that help in Software Testing. In this article, we will discuss BVA and ECP, their benefits, real-life examples, and some common pitfalls to avoid.</p>

<h2 id="h-what-are-boundary-value-analysis-and-equivalence-class-partitioning"><span id="What_are_Boundary_Value_Analysis_and_Equivalence_Class_Partitioning"><strong>What are Boundary Value Analysis and Equivalence Class Partitioning? </strong></span></h2>



<p><strong>Boundary Value Analysis (BVA):&nbsp;</strong></p>



<p>BVA is a testing technique that focuses on testing the boundary conditions of a system. The objective of BVA is to identify and test the values at the boundaries, which are often the most vulnerable points in a software application. These boundaries can include input limits, output limits, or any other type of boundary that is relevant to the system being tested.&nbsp;</p>



<p>The concept of BVA is based on the assumption that errors are more likely to occur at the boundaries of input values, rather than within the range of acceptable values. This is because the boundary values are usually handled differently by the software application, and any discrepancies in the handling of these values can result in errors.</p>



<p>For example, let&#8217;s consider a software application that accepts input values in the range of 1 to 100. The boundary values, in this case, would be 1, 100, and values close to them, such as 2, 99, etc. Testing the boundary values would involve checking how the software application behaves when it receives input values at the edge of the acceptable range. This includes testing values such as 0, 101, -1, 102, and so on.&nbsp;</p>



<p>Contrary to the name it’s less of an analysis but more of a heuristic that can be applied while testing, which means that it can fail too. It is important to note that BVA should not be used as the sole testing technique, but rather as a heuristic that can be applied in conjunction with other testing techniques.&nbsp;</p>



<p><strong>Equivalence Class Partitioning (ECP):</strong><strong>&nbsp;</strong></p>



<p>ECP is an important technique used in software testing. At its core, ECP is about grouping similar items that have a common property into a set, where each set represents an equivalence class. Doing so, helps testers identify and target specific areas of the software that may have a higher likelihood of containing bugs or errors.&nbsp;</p>



<p>When you&#8217;re driving a car, do you consciously calculate the exact amount of pressure needed to apply on the gas pedal to accelerate to a specific speed? No, you don&#8217;t.&nbsp;</p>



<p>You know that pressing the pedal with a certain amount of force will generally get you to the desired speed. This is because the car&#8217;s engine and transmission are designed to work together to achieve a range of speeds, so there is a range of acceptable inputs for achieving a given output. That&#8217;s ECP! We apply it to anything we use regularly, like appliances, tools, and technology.&nbsp;</p>



<p>In the context of software testing, ECP is used to group tests based on various criteria such as input/output values, user groups, product risks, test environments, etc.&nbsp;</p>



<p>For instance, if you are testing a login page, you could group tests based on different input values such as valid usernames and passwords, invalid usernames, invalid passwords, and so on. Each group would represent an equivalence class that exposes different kinds of bugs or issues that may arise when users attempt to log in.&nbsp;</p>



<p>While ECP is an effective testing technique, it is not foolproof, and it can sometimes fail too. It is a thought process that relies heavily on the tester&#8217;s knowledge and experience.&nbsp;</p>

<p>Now that we know about BVA and ECP, it is worth pointing out that they both are usually used together. Let&#8217;s try to understand this with an example. Let’s say you are trying to test a form that accepts age as a number:<br>&#8211; You cannot go on and create 100 test cases for it to test for all 100 inputs from the age of 1 to 100.<br>&#8211; You will also need to test the numbers below 1 and above 100. These are the boundary values.<br>&#8211; To make our testing more effective, let&#8217;s employ ECP. Let’s partition the 1 to 100 into groups of 10, so they would be [1-10];[11-20];[21-30];[31-40];[41-50];[51-60];[61-70];[71-80];[81-90];[91-100];</p>



<p>&#8211; For the created groups, the testing can be done for values on boundaries like: -1;0;1;9;10;11;19;20;21… and so forth</p>

<div class="wp-block-image"><figure class="aligncenter size-full is-resized"><img loading="lazy" src="https://testsigma.com/blog/wp-content/uploads/image-115.png" alt="Benefits of Using BVA &amp; ECP in Software Testing" class="wp-image-29919" width="200" height="200" /></figure></div>



<p>While BVA and ECP are widely used, let&#8217;s understand some of the key benefits of applying BVA and ECP</p>



<p>in software testing:&nbsp;</p>



<p>1. <strong>Improved Understanding of the System Under Test: </strong>When we apply BVA and ECP techniques, we try to identify the boundaries of the system and group the input parameters into classes. This helps us to gain a better understanding of the system and its behavior.&nbsp;</p>



<p>2. <strong>Simplified Test Design: </strong>By grouping the tests based on input/output values, user groups, product risks, test environments, etc., testers can better plan their tests. This ensures that each class is tested comprehensively and exposes different kinds of bugs.&nbsp;</p>



<p>3. <strong>Better <a href="https://testsigma.com/blog/test-coverage/" target="_blank" rel="noreferrer noopener">Test Coverage</a>: </strong>BVA and ECP techniques help to identify critical tests by dividing the input domain into smaller regions, leading to effective test coverage. BVA focuses on testing boundary conditions, which are the most error-prone areas, while ECP divides the input domain into equivalence classes that can be tested as a group. </p>



<p>4. <strong>Better Prioritization: </strong>By using these techniques, we can prioritize the test cases based on their criticality. BVA helps in identifying the values at the boundaries, which are more likely to cause errors, while ECP helps in grouping the tests based on the common properties, which makes it easier to prioritize the tests.&nbsp;</p>



<p>5. <strong>Better Risk Management: </strong>BVA and ECP help to identify and manage risks associated with software testing. By identifying the most critical scenarios, testers can focus on the areas of the software that are most likely to cause problems.&nbsp;</p>



<h2 id="applications-of-bva-ecp-in-software-testing"><span id="Applications_of_BVA_ECP_in_Software_Testingnbsp"><strong>Applications of BVA &amp; ECP in Software Testing</strong><strong>&nbsp;</strong></span></h2>



<div class="wp-block-image"><figure class="aligncenter size-full is-resized"><img loading="lazy" src="https://testsigma.com/blog/wp-content/uploads/image-116.png" alt="Applications of BVA &amp; ECP in Software Testing" class="wp-image-29921" width="600" height="400" /></figure></div>



<p>The most common use/application of BVA and ECP in Software testing is found to be on the input values for the system under test. Apart from input values, the following are some of the other scenarios where these techniques can be applied:&nbsp;</p>



<p><strong>Boundary Value Analysis (BVA):</strong><strong>&nbsp;</strong></p>



<p>1. <strong><a href="https://testsigma.com/blog/database-testing/" target="_blank" rel="noreferrer noopener">Database Testing</a>: </strong>In a database system, BVA can be used to test the boundary conditions of various parameters such as the number of records, data types, field sizes, the minimum and maximum length of character fields, the range of numeric fields, and the maximum number of records that can be stored, etc. </p>



<p>2. <strong>Network Testing: </strong>BVA can be used to analyze the traffic on the network and identify any abnormal conditions or boundary conditions that may cause the network to fail. In network communication protocols, BVA can be applied to test the boundary conditions of data packets,</p>



<p>such as the minimum and maximum packet size, packet header length, and packet content. This technique can help ensure that the protocol will work correctly under a wide range of data transfer scenarios.&nbsp;</p>



<p>3. <strong>Hardware Testing: </strong>BVA can also be applied to hardware components, such as sensors, where boundary conditions like temperature, humidity, and pressure can impact the functionality of the component. By testing these limits, testers can ensure that the hardware component will function correctly under extreme conditions.&nbsp;</p>



<p>4. <strong>Testing of time-based functionality: </strong>BVA can be applied to test the time-based functionality of a system, such as a booking system, to check if it handles the boundaries of time zones, daylight saving time changes, and other related constraints.&nbsp;</p>



<p>5. <strong><a href="https://testsigma.com/guides/ui-testing/" target="_blank" rel="noreferrer noopener">UI Testing</a>: </strong>BVA can be used to test the boundaries of the screen size, font size, color, alignment, and various user interface elements such as text boxes, buttons, drop-down menus, etc. By testing these limits, testers can ensure that the user interface will function correctly when users interact with it in unexpected ways. </p>



<p><strong>Equivalence Class Partitioning (ECP):</strong><strong>&nbsp;</strong></p>



<ol><li><strong>Output values: </strong>Equivalence Class Partitioning can also be used to test output values. For example, if a software application is supposed to return a specific set of outputs for certain input values, you can use ECP to partition the expected output values into equivalent classes and test only one value from each class.&nbsp;</li><li><strong>User roles: </strong>In software testing, ECP can be applied to different user roles. Different user roles may have access to different sets of features or functionality in an application. By applying ECP to user roles, you can identify and test the most critical combinations of user roles and features.&nbsp;</li><li><strong>Time and date: </strong>ECP can also be used to test software applications that rely on time and date data. For example, if an application requires specific actions to be taken at specific times, ECP can be used to partition the relevant time periods into equivalent classes and test only one time from each class.&nbsp;</li><li><strong>Environment: </strong>ECP can also be used to test software applications in different environments. For example, an application may behave differently on different operating systems or with different hardware configurations. By applying ECP to different environments, you can identify and test the most critical combinations of environment and software configurations.&nbsp;</li><li><strong>Error Handling: </strong>ECP can also be used to test error messages. By partitioning error messages into equivalent classes, you can test only one message from each class, ensuring that all possible error messages are tested without the need to test every possible input value that might trigger an error.&nbsp;</li></ol>



<h2 id="should-you-automate-your-tests-for-bva-and-ecp-techniques"><span id="Should_you_automate_your_tests_for_BVA_and_ECP_Techniques"><strong>Should you automate your tests for BVA and ECP Techniques?</strong></span></h2>



<p>You may be wondering whether or not to automate the tests for Boundary Value Analysis (BVA) and Equivalence Partitioning (ECP) techniques. In my opinion, both of these techniques involve testing a range of input values systematically, making them ideal candidates for automation.</p>



<p>Automating your tests for BVA and ECP can be a great way to save time and ensure accuracy in your testing. And with tools like Testsigma available, it&#8217;s easier than ever to automate your tests without the need for extensive coding or technical knowledge.</p>

<h2 id="common-pitfalls-to-avoid-when-using-bva-ecp"><span id="Common_Pitfalls_to_Avoid_When_Using_BVA_ECPnbsp"><strong>Common Pitfalls to Avoid When Using BVA &amp; ECP</strong><strong>&nbsp;</strong></span></h2>



<p>When using Boundary Value Analysis (BVA) and Equivalence Partitioning (ECP) in software testing, it&#8217;s important to avoid certain pitfalls. Some common pitfalls to avoid include:&nbsp;</p>



<p>1. <strong>Restricting to only input values: </strong>BVA and ECP are not limited to input values alone. Testers must consider all possible factors that could affect the software, such as different user groups, product risks, <a href="https://testsigma.com/blog/test-environment/" target="_blank" rel="noreferrer noopener">test environments</a>, invisible boundaries, transitions, conversions, time, and more.&nbsp;</p>



<p>2. <strong>Assuming limits and classes: </strong>It&#8217;s important not to make assumptions about the limits and classes that should be used in testing. The actual limits and classes may differ from what was originally assumed, and testing based on incorrect assumptions can result in missing critical bugs.&nbsp;</p>



<p>3. <strong>Ignoring user behavior: </strong>Testers must take into account the different ways in which users interact with the software. Factors such as user expectations, use cases, and workflows can all have an impact on the software&#8217;s behavior.&nbsp;</p>



<p>4. <strong>Over-reliance on BVA and ECP: </strong>While BVA and ECP are useful techniques, they shouldn&#8217;t be the only testing methods used. Other testing methods, such as <a href="https://testsigma.com/blog/exploratory-testing/" target="_blank" rel="noreferrer noopener">exploratory testing</a> and usability testing, can provide valuable insights that may be missed using BVA and ECP alone.&nbsp;</p>



<p>5. <strong>Not considering edge cases: </strong>Finally, it is important to test edge cases that may not be within the expected range of values. These edge cases may include unexpected inputs or user behavior and can help uncover critical bugs that may otherwise go unnoticed.&nbsp;</p>



<div class="wp-block-image"><figure class="aligncenter size-full is-resized"><img loading="lazy" src="https://testsigma.com/blog/wp-content/uploads/image-118.png" alt="Common Pitfalls to Avoid When Using BVA &amp; ECP" class="wp-image-29925" width="600" height="400" /></figure></div>

<p>Now that we have understood the various aspects of BVA and ECP; and how they can compliment each other. Let’s also throw some light on their differences:</p>



<figure class="wp-block-table"><table><tbody><tr><td>BVA</td><td>ECP</td></tr><tr><td>Here, testing is always done on the boundaries of input values.</td><td>Here, the testing will be done according to the classes created. The input values can be taken from the boundary or from the middle region of the class.</td></tr><tr><td>It involves testing for valid inputs as well as invalid inputs.<br><br>For eg. For testing boundaries for an age input form:&nbsp; 0 &amp; 1 will be valid inputs and -1 will be an invalid input<br><br></td><td>The validity and invalidity of the input values depends on the partition. Either all values in the partition will be a valid input or an invalid input.</td></tr></tbody></table></figure>

<h2 id="h-what-are-the-stages-of-software-testing"><span id="What_are_the_Stages_of_Software_Testing"><strong>What are the Stages of Software 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>
