次に、この例を拡張し、詳細を追加して、さまざまなパーツをテストする方法を確認しましょう。


### 拡張版 **FastAPI** アプリファイル

**FastAPI** アプリに `main_b.py` ファイルがあるとします。

そのファイルには、エラーを返す可能性のある `GET` オペレーションがあります。

また、いくつかのエラーを返す可能性のある `POST` オペレーションもあります。

これらの *path operation* には `X-Token` ヘッダーが必要です。

次に、先程のものに拡張版のテストを加えた、`test_main_b.py` を作成します。

### 3.1 Use `certgen` to Generate a Certificate

Download [`certgen`](https://github.com/minio/certgen/releases/latest) for your specific operating system and platform.

`certgen` is a simple *Go* tool to generate self-signed certificates, and provides SAN certificates with DNS and IP entries:

```sh
./certgen -host "10.10.0.3,10.10.0.4,10.10.0.5"
```
