Vous pouvez ajouter à votre décorateur de *paramètre de chemin* un paramètre `responses`.

Il prend comme valeur un `dict` dont les clés sont des codes HTTP pour chaque réponse, comme `200`, et la valeur de ces clés sont d'autres `dict` avec des informations pour chacun d'eux.

Chacun de ces `dict` de réponse peut avoir une clé `model`, contenant un modèle Pydantic, tout comme `response_model`.

Lá você pode definir:

* O "Item ID", usado na rota.
* O "Token" usado como um parâmetro de consulta.

/// tip | Dica

Perceba que a consulta `token` será manipulada por uma dependência.

Com isso você pode conectar o WebSocket e então enviar e receber mensagens:

        <jsp:param name="menuType" value="dict"/>

이 경우 해당 공급자를 호출하는 종속성을 오버라이드하고 테스트에 대해서만 모의 사용자를 반환하는 사용자 지정 종속성을 사용할 수 있습니다.

### `app.dependency_overrides` 속성 사용하기

이런 경우를 위해 **FastAPI** 응용 프로그램에는 `app.dependency_overrides`라는 속성이 있습니다. 이는 간단한 `dict`입니다.

테스트를 위해 의존성을 오버라이드하려면, 원래 의존성(함수)을 키로 설정하고 오버라이드할 의존성(다른 함수)을 값으로 설정합니다.

그럼 **FastAPI**는 원래 의존성 대신 오버라이드된 의존성을 호출합니다.

Antes de profundizar en el sistema de **Inyección de Dependencias**, vamos a mejorar el ejemplo anterior.

## Un `dict` del ejemplo anterior

En el ejemplo anterior, estábamos devolviendo un `dict` de nuestra dependencia ("dependable"):

Pero luego obtenemos un `dict` en el parámetro `commons` de la *path operation function*.
