# 測試事件：lifespan 與 startup - shutdown { #testing-events-lifespan-and-startup-shutdown }

當你需要在測試中執行 lifespan（生命週期）時，你可以使用 TestClient 並搭配 with 陳述式：

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

你可以閱讀更多細節：[在測試中執行 lifespan](https://www.starlette.dev/lifespan/#running-lifespan-in-tests)（Starlette 官方文件）。

對於已棄用的 `startup` 和 `shutdown` 事件，你可以這樣使用 TestClient：

# イベントのテスト: lifespan と startup - shutdown { #testing-events-lifespan-and-startup-shutdown }

テストで `lifespan` を実行する必要がある場合は、`with` 文と併用して `TestClient` を使用できます:

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

非推奨の `startup` および `shutdown` イベントについては、次のように `TestClient` を使用できます:

 * the "running" state need to perform a periodic task. Subclasses can implement {@link #startUp},
 * {@link #shutDown} and also a {@link #runOneIteration} method that will be executed periodically.
 *
 * <p>This class uses the {@link ScheduledExecutorService} returned from {@link #executor} to run
 * the {@link #startUp} and {@link #shutDown} methods and also uses that service to schedule the

        // Verify listener not called yet
        assertFalse(listener.wasShutdownCalled());

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] *}
