I'd love that, too. I don't think it exists
(I saw this and said "wait, surely that's not true; surely we have a
--max-errors or something ... but from reviewing
compiletest --help, it does not seem to exist...)
--quiet mode off might help, at least in terms of letting you see for yourself which test is actually failling?
Maybe a long sleep + bell sound + UI notification script to be executed -on-fail :)
--on-fail only works at the granularity of
x.py's tests, not within individual
compiletest suites, right?
x.py already fails fast by default; the problem is that the
src/test/ui suite is huge.)
I don't really know,
--on-fail doesn't work locally for me
you want to use
--pass check btw when running UI tests; otherwise you're testing the runtime stuff as well
