Hi there,
I've similarly forayed into the Ruby world, spent time on Jasmine in JS and built a BDD/Mocking framework for ActionScript2. As I am principally a C++ coder, I wanted to bring some of this back to the C++ world.

There are a few things out there, like Igloo, CppSpec, and GoogleMock. I've been crunching through them, making detailed comparisons, tutorials and pointing out where tehy should perhaps join forces to create one decent tool.
