My experience is we are far, far, far better off having a test suite composed of 
isolated test cases than some large, complex library. The reason is because if 
the library fails, it's simply hell for anyone trying to distill the bug out of 
it. Also, large libraries give the illusion of coverage, but in reality tend to 
be some small subset repeated over and over. And they add a lot of time to the 
running of the test suite.
