<p>When it comes to software testing, <a href="https://testsigma.com/guides/functional-testing/" target="_blank" rel="noreferrer noopener">functional testing</a> is a big deal. It ensures that the software does what it&#8217;s supposed to do and meets the users&#8217; needs. To make this happen, functional test cases are created. These cases tell us what steps to take, what results to expect, and what conditions must be met to test the software properly.</p>



<p>Crafting good functional test cases is an art. It requires a deep understanding of the software needs, a sharp eye for detail, and a talent for predicting potential problems. A good test case should be easy to understand, short, and concise.&nbsp;</p>



<p>No ambiguity allowed!</p>

<p>A functional test case is a set of instructions that describe how to test a specific function in a software application. It outlines the steps to take, the expected results, and the preconditions that must be in place before the test can be run.&nbsp;</p>



<p>When writing functional test cases, it&#8217;s crucial to identify input conditions, expected outcomes, and the steps to execute the test. Clear documentation helps testers, developers, and other stakeholders understand the <a href="https://www.simplilearn.com/tutorials/devops-tutorial/fundamentals-of-software-testing" target="_blank" rel="noreferrer noopener">testing process</a> and results.&nbsp;</p>



<p>Functional test cases contribute to the overall quality assurance process by systematically addressing various functionalities and helping deliver reliable and error-free software to end-users.</p>
