How to fix "You gave screen a query of type "query" but only "find" or "get" queries can be used with asynchronous assertions" in React Testing Library
This error occurs when using React Testing Library's queryBy* methods with async assertions like waitFor or findBy*. queryBy* queries are designed for synchronous checks and return null when elements aren't found, while findBy* and getBy* queries handle async operations properly. Understanding the difference between query types prevents this common testing mistake.
