    assert response.status_code == 200, response.text
    assert response.json() == {"message": "Hello World"}
    assert response.headers["X-Cat-Dog"] == "alone in the world"

Y luego puedes establecer el `status_code` en ese objeto de respuesta *temporal*.

```Python hl_lines="1  9  12"
{!../../docs_src/response_change_status_code/tutorial001.py!}
```

Y luego puedes retornar cualquier objeto que necesites, como normalmente lo harías (un `dict`, un modelo de base de datos, etc).
