The kunit_mark_skipped() macro marks the current test as "skipped", with the provided reason. The kunit_skip() macro will mark the test as skipped, and abort the test. The TAP specification supports this "SKIP directive" as a comment after the "ok" / "not ok" for a test. See the "Directives" section of the TAP spec for details: https://testanything.org/tap-specification.html#directives The 'success' field for KUnit tests is replaced with a kunit_status enum, which can be SUCCESS, FAILURE, or SKIPPED, combined with a 'status_comment' containing information on why a test was skipped. A new 'kunit_status' test suite is added to test this.
