Die Datei `main.py` hätte als Inhalt:

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

Die Datei `test_main.py` hätte die Tests für `main.py`, das könnte jetzt so aussehen:

```Python
{!../../docs_src/async_tests/test_main.py!}
```

## Es ausführen

```

The file `main.py` would have:

{* ../../docs_src/async_tests/main.py *}

The file `test_main.py` would have the tests for `main.py`, it could look like this now:

{* ../../docs_src/async_tests/test_main.py *}

In the file `main.py` you have your **FastAPI** app:


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