Libutest is very simple unit testing framework for C. It tries to make writing tests as easy as possible. No more lists of test functions, just put your test routines into a file and hack away.
$ git clone git://github.com/lubomir/libutest.git
$ cd libutest
$ autoreconf -i
$ ./configure --enable-docs
$ make
If you use Debian or Ubuntu, there is a packaged version at my PPA.
There is some documentation available on http://lubomir.github.io/libutest/.
Runtime options are documented with classic --help command-line argument.
