I now and then see comments like this on questions:
first hit after typing "difference between stub and mock " into google: martinfowler.com/articles/mocksArentStubs.html Can you explain why I am googling for you?
imho all programming questions should be welcome, even if they are very easy to find by googling. To be the #1 one place, SO should contain answers for ALL programming questions. Or am I wrong?
