[PATCH] kunit: show error if kunit results are not present

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Uriel Guajardo <urielguajardo@xxxxxxxxxx>

Currently, if the kernel is configured incorrectly or if it crashes before any
kunit tests are run, kunit finishes without error, reporting
that 0 test cases were run.

To fix this, an error is shown when the tap header is not found, which
indicates that kunit was not able to run at all.
