つまり、Python で環境変数から読み取られる値はすべて `str` になり、他の型への変換やバリデーションはコードで行う必要があります。

## Pydantic の `Settings` { #pydantic-settings }

幸いなことに、Pydantic には環境変数から来る設定を扱うための優れたユーティリティがあり、[Pydantic: Settings management](https://docs.pydantic.dev/latest/concepts/pydantic_settings/) で提供されています。

### `pydantic-settings` のインストール { #install-pydantic-settings }

まず、[仮想環境](../virtual-environments.md)を作成して有効化し、`pydantic-settings` パッケージをインストールします:

- It keeps the specific test logic separated from the common test logic.
- You can run those tests in parallel to other projects of the build.

#### Using test fixtures

Sometimes we want to share test fixtures to setup the code under test across multiple projects. There are basically two ways doing so.
