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:

from fastapi import Depends, FastAPI
from fastapi.testclient import TestClient
from inline_snapshot import snapshot

app = FastAPI()


async def user_exists(user_id: int):
    return True


@app.get("/users/{user_id}", dependencies=[Depends(user_exists)])
async def read_users(user_id: int):
    pass


client = TestClient(app)


def test_read_users():
    response = client.get("/users/42")
