### Evento `shutdown` { #shutdown-event }

Para añadir una función que debería ejecutarse cuando la aplicación se esté cerrando, declárala con el evento `"shutdown"`:

{* ../../docs_src/events/tutorial002_py39.py hl[6] *}

Aquí, la función manejadora del evento `shutdown` escribirá una línea de texto `"Application shutdown"` a un archivo `log.txt`.

/// info | Información

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

{* ../../docs_src/app_testing/tutorial004_py39.py hl[9:15,18,27:28,30:32,41:43] *}


Вы можете узнать больше подробностей в статье [Запуск lifespan в тестах на официальном сайте документации Starlette.](https://www.starlette.dev/lifespan/#running-lifespan-in-tests)

{* ../../docs_src/app_testing/tutorial004_py39.py hl[9:15,18,27:28,30:32,41:43] *}

Para los eventos obsoletos `startup` y `shutdown`, puedes usar el `TestClient` así:

import importlib

import pytest
from fastapi.testclient import TestClient


@pytest.fixture(
    name="client",
    params=[
        pytest.param("tutorial001_py39"),
        pytest.param("tutorial002_py39"),
    ],
)
def get_client(request: pytest.FixtureRequest):
    mod = importlib.import_module(f"docs_src.response_status_code.{request.param}")

    client = TestClient(mod.app)
    return client

import importlib

import pytest
from fastapi.testclient import TestClient


@pytest.fixture(
    name="client",
    params=[
        "tutorial001_py39",
        "tutorial003_py39",
    ],
)
def get_client(request: pytest.FixtureRequest):
    mod = importlib.import_module(f"docs_src.first_steps.{request.param}")
    client = TestClient(mod.app)
    return client


@pytest.mark.parametrize(

### Предоставьте доступ к статическим файлам { #serve-the-static-files }

* Импортируйте `StaticFiles`.
* Смонтируйте экземпляр `StaticFiles()` в определённый путь.

{* ../../docs_src/custom_docs_ui/tutorial002_py39.py hl[7,11] *}

### Протестируйте статические файлы { #test-the-static-files }

You should do it after adding all your *path operations*.

{* ../../docs_src/path_operation_advanced_configuration/tutorial002_py39.py hl[2, 12:21, 24] *}

/// tip

If you manually call `app.openapi()`, you should update the `operationId`s before that.

For the deprecated `startup` and `shutdown` events, you can use the `TestClient` as follows:
