We came back again to the fact that chess programs are maded to **play chess**.
So in order to test a chess program you need to let it **play chess**. At least
i haven't seen any fractional tests that can be used to be  sure that your
program "plays chess". Playing high strength chess it's even more complex.

What "good tools" are?

ie. How do you make a unit testing of an static evaluation function?, what
values does it need to return to pass your "good tests"?

Anyway i think i got your point that the better the tests, the better the
confidence of not breaking something.
