I will try to spread more and more the idea, so make more people wanna try it, its a different concept and I mean people still a little afraid to try it. But I will keep going on it, I really believe in the idea :)

Wilker: not sure what you were expecting, but you just announced it on this list 2 days ago :) Give it a bit more time.

Everybody else: come on, people! Many of you have been asking for some sort of auditing tool for mocks that tell you when you're mocking stuff that doesn't exist, and Wilker here is finally offering a workable solution. Feedback, please :)

Cheers,
David

If you take a look at current RSpec Mocks driver on Aidmock[1] you will see that I need to use a lot of "instance_variable_get" to accomplish the work, and it has a serious risk to broke in any rspec-mocks update...
