# テスト

<a href="https://www.starlette.io/testclient/" class="external-link" target="_blank">Starlette</a> のおかげで、**FastAPI** アプリケーションのテストは簡単で楽しいものになっています。

<a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a> がベースなので、非常に使いやすく直感的です。

これを使用すると、**FastAPI** と共に <a href="https://docs.pytest.org/" class="external-link" target="_blank">pytest</a> を直接利用できます。

## `TestClient` を使用

`TestClient` をインポートします。
