Pass arguments of test.sh to test_func/pytest

This is useful if you, for example, want to filter the executed tests
using `-k`.

 Ideally, add some pylint error suppression messages to the file to prevent
 spurious warnings, since these are all tiny little modules not designed to
 do anything so there's no need to be perfect.
