Параметр `lifespan` застосунку `FastAPI` приймає асинхронний менеджер контексту, тож ми можемо передати йому наш новий асинхронний менеджер контексту `lifespan`.

`FastAPI` uygulamasının `lifespan` parametresi bir **async context manager** alır; dolayısıyla oluşturduğumuz yeni `lifespan` async context manager’ını buraya geçebiliriz.

# Events testen: Lifespan und Startup – Shutdown { #testing-events-lifespan-and-startup-shutdown }

Wenn Sie `lifespan` in Ihren Tests ausführen müssen, können Sie den `TestClient` mit einer `with`-Anweisung verwenden:

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

# 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] *}

より詳しい内容は、[公式 Starlette ドキュメントの「テストでの lifespan の実行」](https://www.starlette.dev/lifespan/#running-lifespan-in-tests) を参照してください。

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:

# 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] *}

		{
			name:       "is-not-missing",
			query:      `select * from s3object[*] as s where s.request.header['User-Agent'] is not missing`,
