Re: Mocking collaborators that are third-party libraries

Thanks George.

I am following that advice also (already) so very good to get affirmation
of that.

However, I realize my question was not clear enough so continuing from your
answer, do you always verify behavior on mocked adaptors or are there
occasions where you don't?  That is, you just mock them but don't verify.

I hope my question is clearer.
