Why do you need this instead of having a test PASS when the test checks 
that the error happened correctly?

I think that pretty much anyone doing automated tests so far agree that 
it's better to have just all tests be written in the positive way, so that 
you don't have to ever exchange the meanings of PASS and FAIL.

I believe that this is definitely not a useful feature. I thought you had 
something for helping error handling, but the way you describe it now, it 
sounds like it doesn't actually help in any way.
