/// tip | Tipp

Beachten Sie, dass die Testfunktionen normal `def` und nicht `async def` sind.

Und die Anrufe an den Client sind ebenfalls normale Anrufe, die nicht `await` verwenden.

Dadurch können Sie `pytest` ohne Komplikationen direkt nutzen.

### Exceptions auslösen { #raise-exceptions }

Die Abhängigkeiten können Exceptions `raise`n, genau wie normale Abhängigkeiten:

### Rückgabewerte { #return-values }

Und sie können Werte zurückgeben oder nicht, die Werte werden nicht verwendet.

* The client doesn't have enough privileges for that operation.
* The client doesn't have access to that resource.
* The item the client was trying to access doesn't exist.
* etc.

In these cases, you would normally return an **HTTP status code** in the range of **400** (from 400 to 499).

This is similar to the 200 HTTP status codes (from 200 to 299). Those "200" status codes mean that somehow there was a "success" in the request.

Puedes usar `async def` o `def` normal.

Y puedes declarar dependencias con `async def` dentro de *path operation functions* normales `def`, o dependencias `def` dentro de *path operation functions* `async def`, etc.

No importa. **FastAPI** sabrá qué hacer.
