# Тестирование событий: lifespan и startup - shutdown { #testing-events-lifespan-and-startup-shutdown }

Если вам нужно, чтобы `lifespan` выполнялся в ваших тестах, вы можете использовать `TestClient` вместе с оператором `with`:

# 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] *}

# 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] *}

Used by Starlette:

* [`httpx`](https://www.python-httpx.org) - Required if you want to use the `TestClient`.
* [`jinja2`](https://jinja.palletsprojects.com) - Required if you want to use the default template configuration.
