Ви можете використовувати той самий `TestClient` для тестування WebSocket.

Для цього використайте `TestClient` в інструкції `with`, підключаючись до WebSocket:

{* ../../docs_src/app_testing/tutorial002_py310.py hl[27:31] *}

/// note | Примітка

Докладніше дивіться документацію Starlette щодо [тестування WebSocket](https://www.starlette.dev/testclient/#testing-websocket-sessions).

Você pode usar o mesmo `TestClient` para testar WebSockets.

Para isso, você utiliza o `TestClient` dentro de uma instrução `with`, conectando com o WebSocket:

{* ../../docs_src/app_testing/tutorial002_py310.py hl[27:31] *}

/// note | Nota

Para mais detalhes, confira a documentação do Starlette para [testar WebSockets](https://www.starlette.dev/testclient/#testing-websocket-sessions).

`TestClient` робить певну «магію» всередині, щоб викликати асинхронний застосунок FastAPI у ваших звичайних тестових функціях `def`, використовуючи стандартний pytest. Але ця «магія» більше не працює, коли ми використовуємо його всередині асинхронних функцій. Запускаючи тести асинхронно, ми більше не можемо використовувати `TestClient` у наших тестових функціях.
