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_py39.py hl[27:31] *}

/// note | Nota

Para mais detalhes, confira a documentação do Starlette para <a href="https://www.starlette.dev/testclient/#testing-websocket-sessions" class="external-link" target="_blank">testar WebSockets</a>.

O marcador `@pytest.mark.anyio` informa ao pytest que esta função de teste deve ser invocada de maneira assíncrona:

{* ../../docs_src/async_tests/app_a_py39/test_main.py hl[7] *}

/// tip | Dica

Note que a função de teste é `async def` agora, no lugar de apenas `def` como quando estávamos utilizando o `TestClient` anteriormente.
