I think the style [0] you linked suggests '*_KUNIT_TEST' for config
variables.

Only noticed this because I was doing a
	
	git grep 'config.*TEST'

to find tests in the kernel + new tests floating on the LKML.

Apologies for picking this patch to comment on, but if it's still
changeable it might be worth adjusting.

Not a big deal, but I'm not sure if summarizing KUnit here is useful.
You already link to the documentation below.
