`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"
{!../../docs_src/app_testing/tutorial001.py!}
```

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。

В какой-то момент вы бы начали определение функции, у вас были бы готовы параметры...

Но затем вы должны вызвать «тот метод, который преобразует первую букву в верхний регистр».

Было это `upper`? Или `uppercase`? `first_uppercase`? `capitalize`?

Тогда вы попробуете с давним другом программиста: автодополнением редактора.
