So You Wanna Write A Unit Test

Russ Olsen has posted article on five great tips of writing unit test. I am entirely agree with Russ on second tip "Silence, please", that good unit test should respond only giving results like "will it work or not?". Answer in straight "Yes" or "No" is more relevant than proving all kind of junk information from unit tests. And if a unit test says "No", I can further debug the code and find where the problem is.
