Note that the test suite doesn't fully verify that each validation succeeds; rather, it ensures that the proper system (storage, security scanning, etc) is called with the configuration and returns at all (usually with an expected error). This should prevent us from forgetting to update these code paths when we change config-based systems. Longer term, we might want to have these tests stand up fake/mock versions of the endpoint services as well, for end-to-end testing.
