<h2 id="h-what-is-grey-box-testing">What is Grey Box Testing?</h2>



Grey box testing, which is also called Gray box testing, is a way to debug software and find out if there are any vulnerabilities. In this type of testing, the tester needs to learn more about how the part they&#8217;re testing works.&nbsp;



This differs from black box testing, where the tester doesn&#8217;t know anything, and white box testing, where the tester knows everything.



In these tests, the tester usually knows what&#8217;s inside an application but not exactly how everything works together. This ensures that testing is like what real attackers and users would do.



Grey box testing is best for checking web applications, testing how things work together, looking at things across different systems, testing business ideas, and checking how secure something is.&nbsp;



Testers and developers must stay separate to ensure fair test results when doing this kind of testing.



As you already know, Grey box testing combines black box and white box testing. You can automate entire black box testing using <a href="https://testsigma.com/qa-automation-tools" target="_blank" rel="noreferrer noopener">automation testing tools</a> like Testsigma.&nbsp;
