You have test-driven in other languages but need to sharpen your skills for C or C++. In this session we'll see how to test-drive code using CppUTest and CppUMock. You'll also take the legacy C challenge and use all the tools of the trade to get this code, never meant to be tested off its target environment, into CppUTest. To effectively mock and fake in C and C++ you need to know your tools and use them in creative ways. Each stage of compilation must be mastered to tame the legacy C beast.
