test-o-matic is small enough to be included directly in any project.
#include test_o_matic.hpp where needed and compile and link against
The repository also includes some self-tests. If you just want to start writing tests, you can ignore these.
Compiling test-o-matic's self-tests
python doozer.py test_o_matic/make.py variant=<your-config>.cfg
If you want to compile the tests another way, it should be easy enough. Just do the usual thing with all the
.cpp files and link them in to an executable.
