<h2><span style="font-weight: 400;">Different Forms of QA Testing </span></h2>
<span style="font-weight: 400;">QA testing can be carried out using multiple methods. Listed below are some of the most common forms of QA testing.</span>
<ul>
 	<li style="font-weight: 400;" aria-level="1"><b>Functional Tests</b><span style="font-weight: 400;">: As the name denotes, functional tests concentrate on testing the functionality of a specific app. Functional testing includes offering several inputs, capturing the results, and validating them with the projected outcomes.</span></li>
 	<li style="font-weight: 400;" aria-level="1"><b>Unit Tests</b><span style="font-weight: 400;">: The unit test is a form of automated software testing where separate software elements are individually tested to confirm their functionality. This technique focuses on testing the tiny code units, such as individual methods or functions, to detect and fix bugs early.</span></li>
 	<li style="font-weight: 400;" aria-level="1"><b>Non-functional Tests</b><span style="font-weight: 400;">: In non-functional tests, all the non-functional components of the software are amazingly tested. It chiefly focuses on the performance, security, or data storage facet of the software.</span></li>
 	<li style="font-weight: 400;" aria-level="1"><b>Regression Tests</b><span style="font-weight: 400;">: QA Professionals run regression testing to validate whether a current update or code modification in the software has caused flaws in any current features or not. Since regression testing is typically the same and should be fully or partially re-executed, QA is the most effectual method to conduct it.</span></li>
 	<li style="font-weight: 400;" aria-level="1"><b>Smoke Testing</b><span style="font-weight: 400;">: A smoke test is a form of test automation that focuses on testing all the traits of the software.
