The creator of bup (https://github.com/bup/bup/ https://github.com/bup/bup/) also created wvtest (https://github.com/apenwarr/wvtest https://github.com/apenwarr/wvtest) to "unit test" any code in any combination of language on any platform. It's actually kind of cheating: all you do in your code is write lines with a specific format, and then the wvthing parses that to display stats.
