The test on the feature/MGNLRES-144-resource-servlet-integration-test branch doesn't test much - 6 resources, all on the same origin (the least "interesting" of all, LegacyClasspathOrigin, ie /mgnl-resources/), and all accepted. If anything, we'd need tests that validate the scenarios we're trying to cover with this new features - hotfixes/overrides, serving resources from the different origins, making sure the error codes are ok, cache headers (with the help of the cache filter) are set correctly on author/public with/without devmode etc etc.
