CASE: a Simple Test Framework for C

I created this framework to automate tests in ccv: http://github.com/liuliu/ccv.

Now it is a very "weak" framework comparing to others. The highlight is: simple and pure C. Granted, some hacks are needed to complete this job. But I hope that these hacks are robust enough to be usable.

I am looking for a test framework for some time already and I liked the structure of CATCH (https://github.com/philsquared/Catch) a lot but the only downside is that it is C++ based (I don't want to extern "C" link to my C library). It should be understood that for a good test framework, C may not be syntactically powerful enough to support such syntax sugar. JUnit made heavily use of annotation and many C++ unit testing libraries use static object with constructor (to collect all test cases before main starts). I managed to do this with some macros and stack hacking.

I plan to have some mutation test support in the future.
