Bjorn pointed requested that kunit_tool should use the KUnit defconfig by default if no kunitconfig is present.
Basically, `tools/testing/kunit/kunit.py run` should just work out of the box.
This kind of ties into Ted's comments at LPC that the command to run KUnit tests should be simple. We should have sensible default values for all the flags.
This bug kind of ties into https://bugzilla.kernel.org/show_bug.cgi?id=205253
I have a patch that addresses this here: https://kunit-review.googlesource.com/c/linux/+/2909. Still need to send the patch to LKML.
