I applied your patchset to torvalds/master, ran the command:

tools/testing/kunit/kunit.py run --timeout=60 --jobs=8 --defconfig --build_dir=.kunit

and got the error:

Traceback (most recent call last):
  File "tools/testing/kunit/kunit.py", line 140, in <module>
    main(sys.argv[1:])
  File "tools/testing/kunit/kunit.py", line 123, in main
    create_default_kunitconfig()
  File "tools/testing/kunit/kunit.py", line 36, in create_default_kunitconfig
    kunit_kernel.KUNITCONFIG_PATH)
  File "/usr/lib/python3.7/shutil.py", line 121, in copyfile
    with open(dst, 'wb') as fdst:
FileNotFoundError: [Errno 2] No such file or directory: '.kunit/.kunitconfig'

It seems that it expects the build_dir to already exist; however, I
don't think this is clear from the error message. Would you mind
addressing that here?

Cheers!
