In der Datei `main.py` haben Sie Ihre **FastAPI**-Anwendung:


```Python
{!../../docs_src/app_testing/main.py!}
```

### Testdatei

Dann könnten Sie eine Datei `test_main.py` mit Ihren Tests haben. Sie könnte sich im selben Python-Package befinden (dasselbe Verzeichnis mit einer `__init__.py`-Datei):
