1つのテストクラスメソッドに2つのHttpモックコールアウトを含めることはできますか

私の方法では、1回のトランザクションで2つのコールアウトを作成します

1. そのAPIのアクセストークンを取得する-> GetAccessToken
2. 支払いを実行する

テストクラスを実行すると、次のエラーが発生します08:50:00:839 FATAL_ERROR System.NullPointerException: Argument 2 cannot be null。このコードでは request.setHeader('Authorization', accessTokenValue);

モックアップ応答で、[支払いの実行のみ]を設定していますが、同じメソッドでアクセストークンAPIをモックできますか？モッククラスのみのexecute Payment応答であるため、アクセストークン呼び出しを行うことができないためaccessTokenValue、NULLとして設定されます。

1つのテストクラスメソッドで複数のモックを作成する方法はありますか？これについて私を導いてください。ありがとうございました
