You can learn more about it on https://nemequ.github.io/munit/
Although, this is the pipa's version:
- https://git.sr.ht/~johnnyrichard/pipac/blob/master/test/munit.c
- https://git.sr.ht/~johnnyrichard/pipac/blob/master/test/munit.h
The only change from the original project is that pipa's version
prints errors in a way vim can interprets the test file that fails.
