Sorry for not checking the case.  The 4th patch, "kunit: Place 'test.log' under
the 'build_dir'" made the bug.  I fixed the 4th patch and tested with below
commands:

    ./tools/testing/kunit/kunit.py run --timeout=60 --jobs=12
--defconfig --build_dir .kunit
    ./tools/testing/kunit/kunit.py run --timeout=60 --jobs=12 --defconfig

Just sent the 4th version patchset including the fix:
    http://lkml.kernel.org/r/1575490683-13015-1-git-send-email-sj38.park@gmail.com

I will consider adding some tests that can check such cases in the
'kunit_tools_test.py' later.


Thanks,
SeongJae Park
