Dazu verwenden Sie den `TestClient` in einer `with`-Anweisung, eine Verbindung zum WebSocket herstellend:

# 测试事件：启动 - 关闭

使用 `TestClient` 和 `with` 语句，在测试中运行事件处理器（`startup` 与 `shutdown`）。

# Testing Events: startup - shutdown

When you need your event handlers (`startup` and `shutdown`) to run in your tests, you can use the `TestClient` with a `with` statement:

```Python hl_lines="9-12  20-24"
{!../../../docs_src/app_testing/tutorial003.py!}

	metav1 "k8s.io/apimachinery/pkg/apis/meta/v1"
	corelisters "k8s.io/client-go/listers/core/v1"
	"k8s.io/client-go/tools/cache"
	"k8s.io/component-helpers/storage/volume"
	api "k8s.io/kubernetes/pkg/apis/core"
	pvtesting "k8s.io/kubernetes/pkg/controller/volume/persistentvolume/testing"
)

var class1Parameters = map[string]string{
	"param1": "value1",
}
var class2Parameters = map[string]string{
	"param2": "value2",
}

Wenn Sie in Ihren Tests Ihre Event-Handler (`startup` und `shutdown`) ausführen wollen, können Sie den `TestClient` mit einer `with`-Anweisung verwenden:
