Too complicated. People have even wrecked tools/testing/selftests/ to the point that it is now nearly impossible to run the simple selftests :-( And while I don't mind tests -- they're quite useful. Kunit just looks to make it all more complicated that it needs to be. Not to mention there seems to be snakes involved -- and I never can remember how that works. Basically, if the stuff takes more effort to make run, than the time it runs for, its a loss. And in that respect much of the kernel testing stuff is a fail. Just too damn hard to make work. I want to: make; ./run.sh or something similarly trivial. But clearly that is too much to task these days :-( I spent almost a full day trying to get kvm selftests working a couple of weeks ago; that's time I don't have. And it makes me want to go hulk and smash things.
