Wow, this is excellent results!
successes=619, skipped=43, failures=1, errors=0
successes=642, skipped=20, failures=1, errors=0
successes=644, skipped=18, failures=1, errors=0
In my testing, locally, I had 2 tests that were failing, but the AB only
has one :-) The one that is failing on the AB:
systemd_boot.Systemdboot.test_efi_systemdboot_images_can_be_built
is not one I had tested.
Thanks!
