I noticed that this test is never ran / found by WebKit's run-webkit-tests because it's listed as a resource file in resource-files.json. What's up with that?
Looks like this is a very old bug in TestParser.analyze_test. It can't determine the test type so returns None. find_importable_tests would then classify it as a potential resource file.
