# 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`）。

```Python hl_lines="9-12  20-24"

  open fun enqueueResponse(response: MockResponse) {

# Events testen: Hochfahren – Herunterfahren

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

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

// New returns an empty podProxyOptions object.
func (r *ProxyREST) New() runtime.Object {
	return &api.PodProxyOptions{}
}

// Destroy cleans up resources on shutdown.
func (r *ProxyREST) Destroy() {
	// Given that underlying store is shared with REST,
	// we don't destroy it here explicitly.
}

// ConnectMethods returns the list of HTTP methods that can be proxied
