Criterion

I really like Google Test, but am planning on doing some embedded development in C, where I sometimes find it awkward to test C code using a C++ library. Therefore, I wrote a small unit test library closely mimicking Google Test. It consists of two source files, "rktest.c" and "rktest.h", and is about 1k lines of code and written in C99. It uses a trick for self registering tests by placing pointers to the unit test functions into a known place in program memory, that I first learned about from https://github.com/christophercrouzet/rexo/ and https://github.com/Snaipe/Criterion/.

Developer here. If you have any suggestion/criticism on the project, I'd be happy to know. What this brings on the table compared to other frameworks is a very simple way to write tests, while giving the programmer enough liberty to do what he wants. Criterion achieves that by implementing a xUnit structure with automatic test registration using a declarative syntax -- which means you can be very expressive with the way you declare your tests and suite in a few lines of code. The rest is handled by criterion itself and the default main it provides. Samples: https://github.com/Snaipe/Criterion/blob/bleeding/samples Documentation: http://criterion.readthedocs.org/en/latest/
