Can anyone please help me in diffrentiating between functional & non-functional testing methodologies…
While there is not much difference between functional and non-functional testing from a user point of view, if you look at it as a tester, then you might find many differences between them. Below is a detailed comparison of functional and non-functional testing:
When it comes to the key difference between functional and non-functional testing, it is that functional testing is meant to check on the functionality aspect of the software or application. On the other hand, non-functional testing is meant to test on performance and usability aspects of the product under test.
User acceptance testing, regression testing, interoperability testing, globalization testing are a few examples of functional testing practices. On the other hand, non-functional testing involves scalability testing, reliability testing, volume testing, etc.
