This is a bunch of tests that test some of topotato's functionality itself. I.e. these are not topotato tests, but rather tests that topotato works correctly.
These tests are only relevant when making changes to topotato itself. Some pytest knowledge and python debugging skills are expected.
Follow regular topotato installation instructions. If you run into any issues, you are expected to be able to debug them yourself.
cd selftests
python3 -mpytest
