There are kselftests tests which are shell scripts which load a
module, and the module runs the in-kernel code. However, I didn't see
much infrastructure for the in-kernel test code; the one or two test
modules called from kselftests looked pretty ad hoc to me.

That's why I used the "vise grips" analogy. You can use a pair of
vise grips like a monkey wrench; but it's not really a monkey wrench,
and might not be the best tool to loosen or tighten nuts and bolts.
