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。

### 拡張版テストファイル

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。

{* ../../docs_src/app_testing/app_b/test_main.py *}

	// current cluster does not have the object yet. This is in a site/bucket replication scenario.
	MinIOTaggingProxied = "X-Minio-Tagging-Proxied"

	toNames := func(delObjs []delObj) []ObjectToDelete {
		objs := make([]ObjectToDelete, len(delObjs))
		for i, obj := range delObjs {
			objs[i] = obj.object
		}
		return objs
	}

	// The result of delete operation on all passed objects
	delErrs := make([]error, len(objects))

	// The result of delete objects
	delObjects := make([]DeletedObject, len(objects))

	// A map between a set and its associated objects

        return new MetricsEventListener(call);
      } else {
        return EventListener.NONE;
      }
    }
  };
