### Sub-aplicación { #sub-application }

Luego, crea tu sub-aplicación, y sus *path operations*.

Esta sub-aplicación es solo otra aplicación estándar de FastAPI, pero es la que se "montará":

### Montar la sub-aplicación { #mount-the-sub-application }

{* ../../docs_src/sub_applications/tutorial001_py39.py hl[3, 6:8] *}

### Sub-aplicação { #sub-application }

Em seguida, crie sua sub-aplicação e suas *operações de rota*.

Essa sub-aplicação é apenas outra aplicação FastAPI padrão, mas esta é a que será "montada":

{* ../../docs_src/sub_applications/tutorial001_py39.py hl[11, 14:16] *}

### Monte a sub-aplicação { #mount-the-sub-application }

from fastapi.testclient import TestClient

from docs_src.response_cookies.tutorial002_py39 import app

client = TestClient(app)


def test_path_operation():
    response = client.post("/cookie-and-object/")
    assert response.status_code == 200, response.text
    assert response.json() == {"message": "Come to the dark side, we have cookies"}

## 임의의 `dict` 응답

Pydantic 모델을 사용하지 않고, 키와 값의 타입만 선언하여 평범한 임의의 `dict`로 응답을 선언할 수도 있습니다.

이는 Pydantic 모델에 필요한 유효한 필드/속성 이름을 사전에 알 수 없는 경우에 유용합니다.

이 경우, `typing.Dict`를 사용할 수 있습니다(또는 Python 3.9 이상에서는 단순히 `dict`를 사용할 수 있습니다):

# Testing WebSockets { #testing-websockets }

You can use the same `TestClient` to test WebSockets.

For this, you use the `TestClient` in a `with` statement, connecting to the WebSocket:
