Вы можете использовать тот же `TestClient` для тестирования WebSocket.

Для этого используйте `TestClient` с менеджером контекста `with`, подключаясь к WebSocket:

{* ../../docs_src/app_testing/tutorial002_py39.py hl[27:31] *}

/// note | Примечание

    * Luego devuelve la `response` generada por la correspondiente *path operation*.
* Puedes entonces modificar aún más la `response` antes de devolverla.

{* ../../docs_src/middleware/tutorial001_py39.py hl[8:9,11,14] *}

/// tip | Consejo

{* ../../docs_src/path_params/tutorial003_py39.py hl[6,11] *}

Иначе путь для `/users/{user_id}` также будет соответствовать `/users/me`, "подразумевая", что он получает параметр `user_id` со значением `"me"`.

Аналогично, вы не можете переопределить операцию с путем:

{* ../../docs_src/path_params/tutorial003b_py39.py hl[6,11] *}

Первый будет выполняться всегда, так как путь совпадает первым.
