# WebSockets'i Test Etmek

WebSockets testi yapmak için `TestClient`'ı kullanabilirsiniz.

Bu işlem için, `TestClient`'ı bir `with` ifadesinde kullanarak WebSocket'e bağlanabilirsiniz:

```Python hl_lines="27-31"
{!../../docs_src/app_testing/tutorial002.py!}
```

/// note | "Not"

	case debugBlockInboundMessages:
		c.connMu.Lock()
		block := (<-chan struct{})(args[0].(chan struct{}))
		c.blockMessages.Store(&block)
		c.connMu.Unlock()
	}
}

// wsWriter writes websocket messages.
type wsWriter struct {
	tmp [ws.MaxHeaderSize]byte
}

// writeMessage writes a message to w without allocations.

complements the original file-based storage and allows integration with multiple KMS. A Google Cloud KMS plugin was added and will be usable once the Google side of the integration is complete.

* Websocket requests may now authenticate to the API server by passing a bearer token in a websocket subprotocol of the form `base64url.bearer.authorization.k8s.io.<base64url-encoded-bearer-token>`. ([#47740](https://github.com/kubernetes/kubernetes/pull/47740), [@liggitt](https://github.com/liggitt))...

    The `okhttp-ws` submodule is no longer available and `okhttp-ws` artifacts from previous
    releases of OkHttp are not compatible with OkHttp 3.5. When upgrading to the new package
    please note that the `WebSocket` and `WebSocketCall` classes have been merged. Sending messages
    is now asynchronous and they may be enqueued before the web socket is connected.

これが、Web APIへの非同期⏸🔀⏯コードの利用が理にかなっている理由です。

ほとんどの既存の人気のあるPythonフレームワーク (FlaskやDjangoを含む) は、Pythonの新しい非同期機能ができる前に作成されました。したがって、それらをデプロイする方法は、並列実行と、新機能ほど強力ではない古い形式の非同期実行をサポートします。

しかし、WebSocketのサポートを追加するために、非同期Web Python (ASGI) の主な仕様はDjangoで開発されました。

そのような非同期性がNodeJSを人気にした理由です (NodeJSは並列ではありませんが)。そして、プログラミング言語としてのGoの強みでもあります。

そして、それは**FastAPI**で得られるパフォーマンスと同じレベルです。

* Websocket requests to aggregated APIs now perform TLS verification using the service DNS name instead of the backend server's IP address, consistent with non-websocket requests. ([#49353](https://github.com/kubernetes/kubernetes/pull/49353), [@liggitt](https://github.com/liggitt))

## 0.24.0

* Add support for WebSockets with dependencies and parameters.
    * Support included for:
        * `Depends`
        * `Security`
        * `Cookie`
        * `Header`
        * `Path`
        * `Query`
        * ...as these are compatible with the WebSockets protocol (e.g. `Body` is not).
    * [Updated documentation for WebSockets](https://fastapi.tiangolo.com/advanced/websockets/).
