... und haben den Code für die Tests wie zuvor.

## Testen: erweitertes Beispiel

Nun erweitern wir dieses Beispiel und fügen weitere Details hinzu, um zu sehen, wie verschiedene Teile getestet werden.

### Erweiterte **FastAPI**-Anwendungsdatei

Fahren wir mit der gleichen Dateistruktur wie zuvor fort:
