## Exécuter { #run-it }

Vous pouvez lancer vos tests comme d'habitude via :

<div class="termy">

```console
$ pytest

---> 100%
```

</div>

## En détail { #in-detail }

Le marqueur `@pytest.mark.anyio` indique à pytest que cette fonction de test doit être appelée de manière asynchrone :

{* ../../docs_src/async_tests/app_a_py310/test_main.py hl[7] *}

/// tip | Astuce

@app.exception_handler(RequestValidationError)
async def validation_exception_handler(request: Request, exc: RequestValidationError):
    return JSONResponse(
        status_code=422,
        content=jsonable_encoder({"detail": exc.errors(), "body": exc.body}),
    )


class Item(BaseModel):
    title: str
    size: int


@app.post("/items/")
async def create_item(item: Item):

## Es ausführen { #run-it }

Sie können Ihre Tests wie gewohnt ausführen mit:

<div class="termy">

```console
$ pytest

---> 100%
```

</div>

## Im Detail { #in-detail }

Der Marker `@pytest.mark.anyio` teilt pytest mit, dass diese Testfunktion asynchron aufgerufen werden soll:

{* ../../docs_src/async_tests/app_a_py310/test_main.py hl[7] *}

/// tip | Tipp

Si vous cliquez sur l'icône de cadenas et vous vous déconnectez, puis réessayez la même opération, vous obtiendrez une erreur HTTP 401 :

```JSON
{
  "detail": "Not authenticated"
}
```

            },
            "HTTPValidationError": {

Якщо натиснути значок замка й вийти з системи, а потім знову спробувати ту саму операцію, ви отримаєте помилку HTTP 401 такого вигляду:

```JSON
{
  "detail": "Not authenticated"
}

            },
            "HTTPValidationError": {
