We need to become a self-regulating and self-policing profession. The stakes are simply too high to allow software to remain in the current ad-hoc limbo...more.
There’s a bit you need to flip in your head. It’s just one bit. In this blog we’ll call it “THE BIT”. Some...more.
My first exposure to mock objects was in C++, where they are practically indecipherable to the TDD newbie, so I didn't use them. That...more.
