## Suporte de editor em todo canto { #editor-support-everywhere }

E você obtém suporte do editor em todos os lugares.

Mesmo para itens dentro de listas:

Schreiben Sie einfache `assert`-Anweisungen mit den Standard-Python-Ausdrücken, die Sie überprüfen müssen (wiederum, Standard-`pytest`).

{* ../../docs_src/app_testing/tutorial001_py39.py hl[2,12,15:18] *}

/// tip | Tipp

Beachten Sie, dass die Testfunktionen normal `def` und nicht `async def` sind.

Und die Anrufe an den Client sind ebenfalls normale Anrufe, die nicht `await` verwenden.

Use the `TestClient` object the same way as you do with `httpx`.

Write simple `assert` statements with the standard Python expressions that you need to check (again, standard `pytest`).

{* ../../docs_src/app_testing/tutorial001_py39.py hl[2,12,15:18] *}

/// tip

Notice that the testing functions are normal `def`, not `async def`.

And the calls to the client are also normal calls, not using `await`.

## 연결 해제 및 다중 클라이언트 처리

WebSocket 연결이 닫히면, `await websocket.receive_text()`가 `WebSocketDisconnect` 예외를 발생시킵니다. 이를 잡아 처리할 수 있습니다:

{* ../../docs_src/websockets/tutorial003_py39.py hl[79:81] *}

테스트해보기:

* 여러 브라우저 탭에서 앱을 엽니다.
* 각 탭에서 메시지를 작성합니다.
* 한 탭을 닫아보세요.

`WebSocketDisconnect` 예외가 발생하며, 다른 모든 클라이언트가 다음과 같은 메시지를 수신합니다:

```

    SQLModel.metadata.clear()
    # Clear the Models associated with the registry, to avoid warnings
    default_registry.dispose()
