To promote user-centric testing, React Testing Library has async utilities that mimic the user behavior of waiting. In fact, even in the first green test, react warned us about something going wrong with an "act warning", because actual update after fetch promise was resolved happened outside of RTL's act wrappers: Now, that we know what exactly caused the error, let's update our test.
