`TestClient` をインポートします。

`TestClient` を作成し、**FastAPI** に渡します。

`test_` から始まる名前の関数を作成します (これは `pytest` の標準的なコンベンションです)。

`httpx` と同じ様に `TestClient` オブジェクトを使用します。

チェックしたい Python の標準的な式と共に、シンプルに `assert` 文を記述します。

```Python hl_lines="2  12  15-18"

```

テスト関数は `async def` ではなく、通常の `def` であることに注意してください。
