> Something that cannot be tested is something that you cannot know if it works or not. And sometimes that's okay. Suppose you are partnering with a SAAS to release their alpha API as their first client. Maybe don't bother writing too many mocks against the SAAS, because the API is likely to change really quickly. You cannot know if it works, and that's okay, because there is generally not an expectation that it should continue to work, even if you knew it worked today.
