/// 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.

But if you go with your browser to <a href="http://127.0.0.1:8000/app" class="external-link" target="_blank">http://127.0.0.1:8000/app</a> you will see the normal response:

```JSON
{
    "message": "Hello World",
    "root_path": "/api/v1"
}
```

So, it won't expect to be accessed at `http://127.0.0.1:8000/api/v1/app`.

    // ... rest of normal connection logic ...
}

private void requestDurableHandle() {
    Configuration config = context.getConfig();
    
    // Determine handle type based on configuration and server capabilities

Pero si vas con tu navegador a <a href="http://127.0.0.1:8000/app" class="external-link" target="_blank">http://127.0.0.1:8000/app</a> verás el response normal:

```JSON
{
    "message": "Hello World",
    "root_path": "/api/v1"
}
```

Así que no se esperará que sea accedido en `http://127.0.0.1:8000/api/v1/app`.

## Special types and validation { #special-types-and-validation }

Apart from normal singular types like `str`, `int`, `float`, etc. you can use more complex singular types that inherit from `str`.
