Single header library for writing unit tests in C made with fewer complications by avoiding boilerplate. Comparing to other similar libraries this focus on minimizing tests setup and prints direct paths with line number to failed assertions and tests.
I would like to say that code is simple but it's mostly macro magic and global state. So better hold your wizards hat while reading.
Detailed documentation can be found inside library file walter.h.
Examples can be found in demo/ and demo.t.c.
walter.h Library, includes licence and documentation
build Script to builds demo test programs and demo.t.c
demo/ Demonstration programs
snap/ Snapshots of expected output in demo.t.c tests
Should work on POSIX systems. Should NOT work on Windows.

I just realized that I can easily work with standard input, output and error when running commands but I can't do that with functions. Now I'm in need of such capability. This has to be thought through and at the moment I don't have any clear vision. It might be difficult I'll come back later.
Another thing. The basic assertion macros where fine for all my use cases so far but having just the OK() macro for testing numbers is not convenient when the assertion fails. This is because unlike in string assertions, OK() macro will not print what was the actual value when it was not what we expected. There is a way to do generics in C and by that I could handle all the different numbers with single macro but I would like to avoid generics.
