Currently, kunit_skip() and kunit_mark_skipped() will overwrite the current test's status even if it was already marked FAILED.
E.g. a test that just contains this KUNIT_FAIL(test, "FAIL REASON"); kunit_skip(test, "SKIP REASON"); will be marked "SKIPPED" in the end.
Now, tests like the above don't and shouldn't exist. But what happens if non-test code (e.g. KASAN) calls kunit_fail_current_test()?
E.g. if we have if (do_some_invalid_memory_accesses()) kunit_skip("); then the KASAN failures will get masked!
This patch: make it so kunit_mark_skipped() does not modify the status if it's already set to something (either already to SKIPPED or FAILURE).
Before this change, the KTAP output would look like # example_simple_test: EXPECTATION FAILED at lib/kunit/kunit-example-test.c:23 FAIL REASON ok 1 example_simple_test # SKIP SKIP REASON
After this change: # example_simple_test: EXPECTATION FAILED at lib/kunit/kunit-example-test.c:23 FAIL REASON # example_simple_test: status already changed, not marking skipped: SKIP REASON not ok 1 example_simple_test

Thanks very much: this makes much more sense than the old behaviour.
My only suggestion is that we add a test to verify this behaviour to the kunit_status suite, such as: diff --git a/lib/kunit/kunit-test.c b/lib/kunit/kunit-test.c index 4df0335d0d06..fa114785b01e 100644 --- a/lib/kunit/kunit-test.c +++ b/lib/kunit/kunit-test.c @@ -510,9 +510,33 @@ static void kunit_status_mark_skipped_test(struct kunit *test) KUNIT_EXPECT_STREQ(test, fake.status_comment, "Accepts format string: YES"); }

Otherwise, this looks great!
