C is one of the easier languages to do unit testing in: 1. write a new one file script which parses function declarations from a source code file 2. have the script find all function declarations which start with "utest_", accept no parameters, and return "int" or "bool". 3. have the script write out a new C file which calls all of matching unit test functions and asserts their return value is equal to 1 4. have your Makefile build and run a unit test binary using code generated by your script for each source code file containing greater than 0 unit tests. Writing a script to parse function declarations from your C source code is useful because you can extend the script later on to generate documentation, code statistics, or conduct project-specific static analysis.
