ACCU London's July 2011 talk was about mocking in C++, given by Ed Sykes and hosted by 7 City.
Ed talked about MockItNow and Hippomocks. He pointed out, as has been said many times before Mocks aren't Stubs.
I can no longer remember all the details so will have to try these out for myself to see how they work.
Many thanks to Ed for a great talk, though.
