I'll try to add more comments when respin this series.

I guess I should also add a documentation similar to the one I wrote
for IGT [1]:
https://gitlab.freedesktop.org/drm/igt-gpu-tools/-/blob/master/docs/test_documentation.md?ref_type=heads#documenting-tests-via-testplan

[1] this document is specific for the way IGT uses it; I'll write
something similar to it considering the names we've agreed for
KUnit.

No particular reason. I'll change it to be under dev-tools/tests at
the next submission.

Should I wait for you to take a look at patch 1/2 before sending
a new version?
