# Testing Events: lifespan and startup - shutdown { #testing-events-lifespan-and-startup-shutdown }

When you need `lifespan` to run in your tests, you can use the `TestClient` with a `with` statement:

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


You can read more details about the ["Running lifespan in tests in the official Starlette documentation site."](https://www.starlette.dev/lifespan/#running-lifespan-in-tests)

# Tester les événements : lifespan et startup - shutdown { #testing-events-lifespan-and-startup-shutdown }

Lorsque vous avez besoin d'exécuter `lifespan` dans vos tests, vous pouvez utiliser `TestClient` avec une instruction `with` :

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

# 测试事件：lifespan 和 startup - shutdown { #testing-events-lifespan-and-startup-shutdown }

当你需要在测试中运行 `lifespan` 时，可以将 `TestClient` 与 `with` 语句一起使用：

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

你可以在[官方 Starlette 文档站点的“在测试中运行 lifespan”](https://www.starlette.dev/lifespan/#running-lifespan-in-tests)阅读更多细节。

对于已弃用的 `startup` 和 `shutdown` 事件，可以按如下方式使用 `TestClient`：

		cancelGlobalContext()

		if httpServer := newHTTPServerFn(); httpServer != nil {
			if err := httpServer.Shutdown(); err != nil && !errors.Is(err, http.ErrServerClosed) {
				shutdownLogIf(context.Background(), err)
			}
		}

		if objAPI := newObjectLayerFn(); objAPI != nil {
			shutdownLogIf(context.Background(), objAPI.Shutdown(context.Background()))
		}

		if globalBrowserEnabled {
			if srv := newConsoleServerFn(); srv != nil {

	natsserver "github.com/nats-io/nats-server/v2/test"
)

func TestNatsConnPlain(t *testing.T) {
	opts := natsserver.DefaultTestOptions
	opts.Port = 14222
	s := natsserver.RunServer(&opts)
	defer s.Shutdown()

	clientConfig := &NATSArgs{
		Enable: true,
		Address: xnet.Host{
			Name:      "localhost",
			Port:      (xnet.Port(opts.Port)),
			IsPortSet: true,
		},
		Subject: "test",
	}

イベントハンドラ関数は複数追加できます。

すべての `startup` イベントハンドラが完了するまで、アプリケーションはリクエストの受け付けを開始しません。

### `shutdown` イベント { #shutdown-event }

アプリケーションがシャットダウンするときに実行すべき関数を追加するには、イベント `"shutdown"` で宣言します:

{* ../../docs_src/events/tutorial002_py310.py hl[6] *}

ここでは、`shutdown` のイベントハンドラ関数が、テキスト行 `"Application shutdown"` をファイル `log.txt` に書き込みます。

/// info | 情報

                  // which case we should skip right down to shutdown.
                  if (isRunning()) {
                    try {
                      AbstractExecutionThreadService.this.run();
                    } catch (Throwable t) {
                      restoreInterruptIfIsInterruptedException(t);
                      try {
                        shutDown();
                      } catch (Exception ignored) {

            return t;
        };
        cleanupExecutor = Executors.newSingleThreadScheduledExecutor(threadFactory);

        // Add shutdown hook for cleanup
        Runtime.getRuntime().addShutdownHook(new Thread(this::shutdown, "ResourceManager-Shutdown"));

        startCleanupTask();
    }

    /**
     * Get the singleton instance
     *
     * @return ResourceManager instance
     */

# Testando eventos: lifespan e inicialização - encerramento { #testing-events-lifespan-and-startup-shutdown }

Quando você precisa que o `lifespan` seja executado em seus testes, você pode utilizar o `TestClient` com a instrução `with`:

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