It would be nice if oe-selftest had the same kind of two-step interrupt that bitbake implements, i.e. Ctrl+C once would end after the current test and Ctrl+C a second time would interrupt the current test. In each case though it would be even better if oe-selftest printed the final report even if interrupted, so you can see the details of any failed tests without having to wait or re-run just the failed tests.
I think we do this so it may be obsolete.
With bitbake yes - AFAIK not for oe-selftest.
Still a valid enhancement.
Nice to have only but a bit hard to do and we have more important bugs to fix and features to work on.
