I believe functional testing is testing of two or more modules together with the intent of finding defects, demonstrating that defects are not present, and verifying that the module performs its intended functions.
Is there any functional testing tool for java applications? I'm in need to do this. I know of junit which I have used in unit testing and also T2 utility which is an extension of junit, which I have used for automated testing. Is there any particular framework or tool for functional testing?
