<h3 id="h-what-is-buddy-testing">What is Buddy Testing?</h3>



Buddy testing is like having a second pair of eyes on your code. It&#8217;s a great way to catch bugs you might miss alone.



In my view, when two people (i.e., developer &amp; tester or two testers) work together closely on&nbsp;



<ul><li>the same module,&nbsp;</li><li>actively sharing ideas and</li><li>&nbsp;jointly identifying defects and bugs within the application</li></ul>



they ensure the quality of the product. This increases the efficiency rate of the work and even less time conception.



This approach has become increasingly popular in recent years due to its&nbsp;



<ul><li>numerous benefits,&nbsp;</li><li>improved collaboration,&nbsp;</li><li>efficiency, and</li><li>effectiveness in finding defects.&nbsp;</li></ul>



Buddy testing is now being used in various new and innovative ways.&nbsp;



For example, some teams use buddy testing to test artificial intelligence (AI) and machine learning (ML) systems.



Did you know that buddy testing can help to improve the morale of software testing teams?&nbsp;



By working together and sharing ideas, buddy testers can feel more connected to their work and each other.



<h3 id="h-importance-of-buddy-testing">Importance of Buddy Testing</h3>



Buddy testing is essential because it can help improve software product quality.&nbsp;



By working together, buddy testers can identify more defects, reduce the risk of errors, and improve the overall efficiency of the testing process.



<ul><li>Improved collaboration and communication: Buddy testing fosters a collaborative environment where testers and developers can share ideas, learn from each other, and identify defects more effectively.</li></ul>



<ul><li>Increased efficiency and effectiveness: Buddy testing can reduce the time and resources required for testing while also improving the overall quality of the testing process.</li></ul>



<ul><li>Enhanced defect detection: By combining their perspectives and expertise, buddy testers are more likely to find defects that would otherwise be missed.</li></ul>



<ul><li>Improved software quality: By identifying and addressing defects early on, buddy testing can help ensure that the final software product is high quality.</li></ul>



<ul><li>Code deployed to a new environment: Buddy testing is a good way to test code before it is deployed to a new environment, such as production.</li></ul>



Sometimes, pairing up works, and sometimes, we are tied up with the wrong buddies. In the next section, we will read about when and when not to perform this buddy testing.



<h3 id="h-when-to-perform-buddy-testing">When TO perform Buddy Testing?</h3>



Buddy testing can be performed at any stage of the software development lifecycle, but it is most commonly performed during integration and system testing.&nbsp;



<ul><li>Buddy testing is particularly beneficial for&nbsp;<ol><li>testing complex or critical functionality,&nbsp;</li><li>new or unfamiliar code, and&nbsp;</li><li>code modified by multiple developers.&nbsp;</li></ol></li></ul>



Buddy testing can be a very effective way for new testers to learn the testing process and gain experience with different software products and technologies.



<h3 id="h-when-not-to-use-buddy-testing">When NOT to use Buddy testing?</h3>



There are times when buddy testing might not go right! Please do not do this testing during circumstances like:



<ol><li>Team members are optional if the product should undergo automation testing.&nbsp;</li><li>We can not do this test if there is a mismatch in the character or attitude of the two team members who do the testing. Pair testing should be avoided to prevent potential conflicts.&nbsp;</li><li>In cases where only structured test cases are available, a single tester will be sufficient.</li></ol>



<h3 id="h-buddy-testing-process">Buddy Testing Process</h3>



The steps involved in buddy testing:



<ol><li>Identify the primary tester and the buddy tester:</li></ol>



The primary tester is typically an experienced tester with a strong understanding of the software or system being tested. In contrast, the buddy tester may be a less professional or a subject matter expert with knowledge of the domain being tested.



<ol start="2"><li>Define the scope and objective:</li></ol>



The primary tester and the buddy tester should agree on the scope and <a href="https://www.linkedin.com/advice/0/how-do-you-define-scope-objectives-software-testing" target="_blank" rel="noreferrer noopener">objectives of the testing</a>, including the certain features or functionality that will be tested and the expected results. This will help to make sure that the testing is focused and efficient.



<ol start="3"><li>Plan the testing:</li></ol>



The primary tester and the buddy tester should develop a testing plan of specific test cases and test scenarios that will be executed. As well as the resources and tools needed to complete the testing. This will help ensure the testing is complete and all relevant areas are covered.



<ol start="4"><li>Execute the testing:</li></ol>



The primary tester performs the testing while the buddy tester observes and provides assistance. The buddy tester may also document defects and issues identified during the testing. This collaborative approach can help to identify weaknesses and enhance the overall grade of the testing.&nbsp;



<ol start="5"><li>Review and debrief:</li></ol>



After the testing, the primary and buddy tester should review the results and debrief to discuss any issues or challenges. This will support identifying improvement areas and ensure the testing process is continually refined.&nbsp;



<h3 id="h-how-to-do-buddy-testing-in-testsigma">How to do Buddy Testing in Testsigma?</h3>



Buddy Testing is not possible directly in Testsigma but it does support review workflow which enables another tester to review the work done by the tester.



Let’s see how the review feature works in Testsigma:



Login to your Testsigma account before you get started.



First, you must enable the review management feature from the settings module.&nbsp;



The picture below explains it.



<figure class="wp-block-image"><img src="https://lh7-us.googleusercontent.com/pLqHZ3vbtmIn9FrEkmwBHn6Xo2AX52X2ZWyUTaRWx9cuhJWIVJ-HWrXPtRjaqseq0yyVLR9BP-2qBHs3_01_Tkin8oioGYTg39KgpQOpD8xqcNuv4KuN90fLGHTGoitqrCt4foYo43tgSPzGNIYBudQ" alt="admin setting" /></figure>



For example, let us say Tester 1 sends his testcase for review to Tester 2. It looks like the following image.



<figure class="wp-block-image"><img src="https://lh7-us.googleusercontent.com/9IEIw6oQzBgpn1m2rPqYJSisIs1kQG3RFFVjXXmy1RWKEmcayjXBQuZkRlZuCglOk4a_Ss18Zp_Qy59wKUzMY4Gm9CAMSDQjds6WRPRSD5G01Q1RH4mRtnpIM6jQ5WtqphdYffr7ff5VgUmU_g2x8ls" alt="submit review" /></figure>



After submitting for review, here&#8217;s an example of how the dashboard for Tester 1 will look.



<figure class="wp-block-image"><img src="https://lh7-us.googleusercontent.com/Z06SoXOqyGs8wIJ_KNXfrh1NraGLTdnHHocdavT3om05oOdaWYoMOqcJugg-LGRncUV-sp4kWQc6_jTeHK8O0cnt4FwuDd0WUQAzRQfQqRHZRlaf0Zdy4RA2TFWaz75cGR-wFlhUlv9tpThw-LTeGXU" alt="Dashboard" /></figure>



After receiving a test case for review, this is how the Tester 2 dashboard will appear.



<figure class="wp-block-image"><img src="https://lh7-us.googleusercontent.com/Cy8-GT0b4FePoIAWx3iJAXWZhKRLxjCMLKPkdPMkwSU7PQtfw2BCPqv5At37F3n3HU33_mI-I_5bf6u_7Rm9ajDQLurhvUI8R91d0QbiF1uMW7Q8CRP3A1SY-vhsy3p40wZd9pNz_nas2VlUYCKgxz0" alt="buddy testing testcase" /></figure>



This is how Tester 2 can review and mark a test case as done.



<figure class="wp-block-image"><img src="https://lh7-us.googleusercontent.com/n9qt_qabuk48MvUefQF0aIQI5Bskf6IcRRbRFmbu0Xwv6d4d4ez-ZBL7BUUAoXW8HXDBIVZ_eHRAHOYCuAVhKqHvKXeKZN0-6AI9AUTG5dBQImXHecZp1L4-Vuv5qKg_4zncwK_yi6681ncFNAhy1Rg" alt="review status" /></figure>

<h2 id="h-what-is-model-based-testing">What is Model Based Testing?</h2>



Model-based testing, often abbreviated as MBT, is a systematic approach to software testing where abstract models are used as a basis for designing and generating test cases. These models represent the expected behaviour of the system under test, including various states, inputs, and expected outcomes. Test cases are automatically derived from these models, reducing the need for manual test case design. This method aims to increase testing efficiency, improve <a href="https://testsigma.com/blog/test-coverage/" target="_blank" rel="noreferrer noopener">test coverage</a>, and facilitate early defect detection by aligning the testing process with the models created, making it an essential tool in modern software quality assurance.



<h2 id="h-model-based-testing-example">Model Based Testing Example</h2>



For instance, if you have a transition in the model from &#8220;Login&#8221; to &#8220;Transfer Funds,&#8221; the testing tool can automatically generate test cases. These cases ensure that the application allows users to log in successfully, select accounts for transferring funds, and verifies that the transaction is executed accurately.



As the banking application evolves with new features or updates, you can adapt the model, and the testing tool will automatically generate updated test cases. This approach streamlines testing, enhances coverage, and accelerates the detection of defects, making Model-Based Testing an asset in ensuring software quality.

<h2 id="h-how-model-based-testing-works">How Model based testing works?</h2>



Model-Based Testing (MBT) is a systematic approach to software testing that uses abstract models to design and generate test cases. Here are the seven key steps in how MBT works, with a more detailed explanation for each step, consisting of three points:



<ol><li>Model Creation: </li></ol>



<ul><li>Create an abstract model that represents the expected behaviour of the system under test. This model defines states, transitions, and inputs. </li><li>The model can use various techniques, such as finite state machines, statecharts, or decision tables. </li><li>The modelling process often involves collaboration between testers, developers, and domain experts to ensure accuracy. </li></ul>



<ol start="2"><li>Model Validation: </li></ol>



<ul><li>The created model is subject to validation to ensure it accurately reflects the intended system behaviour. </li><li>Validation involves reviews, inspections, and simulations to ensure the model&#8217;s correctness. </li><li>Stakeholders, including domain experts and developers, provide feedback to validate the model. </li></ul>



<ol start="3"><li>Test Case Generation: </li></ol>



<ul><li>Once the model is validated, <a href="https://testsigma.com/guides/what-is-test-case/" target="_blank" rel="noreferrer noopener">test cases </a>are automatically generated from the model. </li><li>These test cases are derived from the model&#8217;s states, transitions, and inputs, ensuring that various system behaviours are covered. </li><li>Automated test case generation saves time and effort compared to manual test case design. </li></ul>



<ol start="4"><li>Test Execution: </li></ol>



<ul><li>The generated test cases are executed against the actual system under test. </li><li>This involves interacting with the software, providing inputs, and observing how the system responds. </li><li>The behaviour of the system is closely monitored during test execution. </li></ul>



<ol start="5"><li>Result Comparison: </li></ol>



<ul><li>During test execution, the observed behaviour of the system is compared to the expected behaviour defined in the model. </li><li>Testers compare the actual outcomes with the predicted outcomes, and any discrepancies are identified. </li><li>This step helps in identifying failures or issues in the software. </li></ul>



<ol start="6"><li>Defect Reporting: </li></ol>



<ul><li>When discrepancies or defects are discovered during testing, they are reported to the development team. </li><li>Early defect detection is a significant advantage of MBT, allowing for timely resolution of issues. </li><li>Detailed defect reports typically include information on the issue, the test case that triggered it, and the model element involved. </li></ul>



<ol start="7"><li>Model Maintenance and Iteration: </li></ol>



<ul><li>As the system evolves or changes are made, the abstract model is updated to reflect these modifications. </li><li>Test cases can be regenerated based on the updated model, ensuring that testing remains aligned with the current state of the application.</li></ul>



<ul><li>The iterative nature of MBT allows for continuous refinement and adaptation based on feedback and evolving requirements.</li></ul>



<h2 id="h-uses-in-test-automation">Uses in test automation&nbsp;</h2>



Model-Based Testing (MBT) offers several uses in test automation, including: 



<ul><li>Test Case Generation: Model-Based Testing (MBT) automates the creation of test cases, reducing manual effort and ensuring systematic coverage of different system states and transitions.</li></ul>

Static analysis or static code analysis is used by developers and software testers to detect coding defects. Static analysis in software testing is not new, at least not for software testers with coding knowledge or experience. Static analysis involves reviewing the code similarly to performing a code or peer review.&nbsp;



Static analysis helps software testers fully understand how the code functions and its structure. Software testers can execute code in isolation and review for errors. Static analysis reviews by software testers also help ensure code meets organizational and industry standards.&nbsp;



This guide describes the types of static code analysis in software testing, how it’s performed, and its benefits for software testing coverage.&nbsp;

<h2 id="h-how-is-static-code-analysis-done">How is static code analysis done?</h2>



Static analysis like other <a href="https://testsigma.com/guides/software-testing/" target="_blank" rel="noreferrer noopener">software testing</a> can be done either manually or by using automation. Static analysis in software testing typically occurs early in the development process. Static code analysis can fulfill testing responsibilities when it’s not possible to test a feature fully in the application.&nbsp;



If static analysis is performed manually it is done either by using pair testing with a developer or by stepping through the code line by line in a formal setting similar to a code review. In either case, the software tester must follow along and ask any questions necessary to understand the functionality. It’s important to consider the individual code under review as well as its impact on the application functionality as a whole. The code is executed manually to verify no errors exist.&nbsp;



When static analysis is performed using automated tools, testers typically use a static code analyzer tool. Static code analyzer tools check the code against defined rules and any related standards. Most tools allow users to determine what standards are checked and to set custom guidelines as well. The code is executed by the tool, and any issues are flagged for review.&nbsp;



<h2 id="h-types-of-static-analysis">Types of static analysis</h2>



Static analysis in software testing is not all the same. There are several different types of static analysis to fit various testing needs.&nbsp;



Typical static analysis methods include:



<ul><li>Control&nbsp;<ul><li>Tests the <a href="https://en.wikipedia.org/wiki/Control_flow" target="_blank" rel="noreferrer noopener">control flow </a>in a calling structure.&nbsp;</li></ul></li><li>Data&nbsp;<ul><li>Verifies data properties and types.&nbsp;</li></ul></li><li>Error or Fault<ul><li>Verifies error processing and identifies failures in components.</li></ul></li><li>Interface&nbsp;<ul><li>Confirms interface compatibility often using mocked or faked dependencies.</li></ul></li></ul>



<h2 id="benefits-and-drawbacks-of-static-analysis">Benefits and drawbacks of static analysis</h2>



Static code analysis in software testing provides benefits including:



<ul><li>Improved code quality throughout the development cycle</li><li>Provides expanded test code coverage</li><li>Helps to find defects before the code is in production</li><li>Prevention of costly common issues</li><li>Reduces costs by finding issues before code is in test or production</li><li>Improves developer and QA collaboration</li></ul>



<h2 id="h-static-verification-vs-dynamic-verification">Static verification vs. dynamic verification</h2>



Static analysis verification testing differs from the more common dynamic verification testing. The differences are around the test objective and include:

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



Static code analysis in software testing provides testing coverage at the early stages of development as well as throughout the development cycle. Software testers benefit from learning the internal code structure and function which can help create functional and <a href="https://testsigma.com/regression-testing" target="_blank" rel="noreferrer noopener">regression tests</a> that execute defined code components in full.&nbsp;



For fuller and deeper test cover, consider including testing using static code analysis manually or by using an automated tool.&nbsp;



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



<h3 id="h-what-is-an-example-of-static-analysis">What is an example of static analysis?</h3>



In the example below, the OWASP Lapse+ tool provides a typical interface for viewing and analyzing code components:



<div class="wp-block-image"><figure class="aligncenter"><img src="https://lh5.googleusercontent.com/VicZP7Cnl49PmTVe2GlJRn0shlA38Fnv5qTYhoBoIEW-WFG8oMWfmMrCKS2LNx9_XAH3_5ejPCt2J_JolxEgwOC6g04I8mb2UcAjXDNNaC7uU9YaU1F-yQQuzdVHRGhdaiZAIeSFCpgXaitDPHVoz2s" alt="What is an example of static analysis"/></figure></div>



<h3 id="why-is-it-called-static-code-analysis">Why is it called static code analysis?</h3>



Because the testing is performed outside the application UI. Since the code is not being executed dynamically as required, it is static. Testers are reviewing and stepping through code components that are not active.
