I care about `make install` for tests at the moment, for CI. For
CI you need to build kernel, install (and save/pack) the tests,
then boot the kernel and run the tests. It deals with OUTPUT, I
looked how to do it properly and found what I found.
My understanding, that it was supposed to work the way you
described. But looks like I'm wrong.
