Question

What\'s the actual use of \'fail\' in JUnit test case?

Answer 1

Let's say you are writing a test case for a negative flow where the code being tested should raise an exception.

try{
   bizMethod(badData);
   fail(); // FAIL when no exception is thrown
} catch (BizException e) {
   assert(e.errorCode == THE_ERROR_CODE_U_R_LOOKING_FOR)
}
