I was at: Unit Testing Training

I've been trying to improve my skills in direction of software craftsmanship.

First thing's first : the difference between mocks and stubs is now clear.
When do i use stubs and with what intent - talking about code review ( unit tests are code as important as production code towards the value added paradigm).

When do I use mocks and most important at what stage of the development process could one insist on using mocks.

Ideas are a great thing so now I can say that reading about this subject and doing this training gives a much clear picture how to do it (crafts). It's still fuzzy but I'm confident i'm getting there one step at a time.
