# 测试 WebSockets { #testing-websockets }

你可以使用同一个 `TestClient` 来测试 WebSockets。

为此，在 `with` 语句中使用 `TestClient` 连接到 WebSocket：

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

/// note | 注意

更多细节请查看 Starlette 的文档：[测试 WebSockets](https://www.starlette.dev/testclient/#testing-websocket-sessions)。

# Event'leri Test Etme: lifespan ve startup - shutdown { #testing-events-lifespan-and-startup-shutdown }

Test'lerinizde `lifespan`'ın çalışması gerektiğinde, `TestClient`'ı bir `with` ifadesiyle kullanabilirsiniz:

{* ../../docs_src/app_testing/tutorial004_py310.py hl[9:15,18,27:28,30:32,41:43] *}

And in many cases, reading them would be a blocking operation (that could block the event loop), because they are read from disk or from the network.

/// info

The example above is actually an exception, because the `io.BytesIO` object is already in memory, so reading it won't block anything.

But in many cases reading a file or a file-like object would block.

also used by other elastic teams like `elasticsearch-hadoop`.
Breaking changes should therefore be avoided and an appropriate deprecation cycle
should be followed.

### Stay up to date

The elasticsearch build usually uses the latest Gradle GA release. We stay as close to the
latest Gradle releases as possible. In certain cases an update is blocked by a breaking behaviour

	defer DetectTestLeak(t)()
	ExecExtendedObjectLayerAPITest(t, testAPIPutObjectPartHandler, []string{"PutObjectPart"})

	credentials auth.Credentials, t *testing.T,

	// Initiate Multipart upload for testing PutObjectPartHandler.
	testObject := "testobject"

This is necessary for bookkeeping when creating new streams. Correct framing requires that stream IDs are sequential on the socket, so we need to bundle assigning the ID with sending the `SYN_STREAM` frame.
