It would be nice to not depend on an out-of-tree test harness (does
anything else in the kernel use this?), especially without a prominent
comment mentioning it.

I've just been doing "sudo sh tests/whatever.t".

Ah, I see, I should document the tests properly, I'll send a patch. To
clarify, "make check" uses Test::Harness on the RTLA tests. It's an
external tool but it seems it is usually installed on RHEL/Fedora so I
went with it.

Ugh, "prove" looks like it's some sort of formal rv thing... misleading
name for just running a test suite.

Yeah not exactly a good name, I always forget how it is named...

It already does print the test name.  If it didn't I probably would have
made more substantial changes to the test harness :-)

Test::Harness only displays it in verbose mode which is not enabled,
since I thought it doesn't look as nice, I was maybe wrong.

Yes, this is used by kselftests [2], which are written in C.

Would it make sense for us to use that?

Though the current docs linking to a wiki that's labelled "obsolete
content" isn't encouraging...

I don't think we need it or it would help us. The RTLA test engine in
bash is good enough IMO and customizable.
