Re: [Q] Number of unit tests in Mauve and of assertions in Classpath?

Hi Stephen,

thanks a lot for that very fast and good answers.

Ah, ok. Sure. Petty though. I am just comparing the number of per- 
postconditions used
with the number of unit tests in some big java case studies.

I guess this 145 are not independent, meaning, if you fixed one, many 
others would be fixed too. Right?

I am just writing a paper stating that it makes sense to sort failing 
tests by size of covered methods beginning with the smallest.
My motivation for asking here, was that if you had assertions (which I 
surely understand that you don't have), more of the failing
tests would fail at the most specific assertion, making my sorting a 
bit more useless.
But hey, you just gave me a wonderful argument: In some big and 
important projects, assertions are even not an option!

Running without failure. So my next questions:

- Do you think sorting failing unit tests would be helpful?
- Does Mauve sort failing unit tests?
- If not, how could it be done?
- Do you know any (as responsive :-) java open source community with 
some big project and which
uses both, JDK 1.4 (thus theoretically assertions) and unit tests?

Thanks a lot - and cheers
