Wenn Sie in Ihren Tests neben dem Senden von Anfragen an Ihre FastAPI-Anwendung auch `async`-Funktionen aufrufen möchten (z. B. asynchrone Datenbankfunktionen), werfen Sie einen Blick auf die [Async-Tests](../advanced/async-tests.md){.internal-link target=_blank} im Handbuch für fortgeschrittene Benutzer.

## Tests separieren

In einer echten Anwendung würden Sie Ihre Tests wahrscheinlich in einer anderen Datei haben.
