# 依存関係のオーバーライドによるテスト { #testing-dependencies-with-overrides }

## テスト時の依存関係のオーバーライド { #overriding-dependencies-during-testing }

テスト中に依存関係をオーバーライドしたい場面がいくつかあります。

元の依存関係（およびそれにぶら下がるサブ依存関係）を実行したくない場合です。

代わりに、テストの間だけ（特定のテストだけでも）使われる別の依存関係を提供し、元の依存関係の値が使われていた箇所で利用できる値を返したいのです。

### ユースケース: 外部サービス { #use-cases-external-service }

例として、呼び出す必要がある外部の認証プロバイダがあるとします。

トークンを送ると、認証済みユーザーが返ってきます。

          .that(ex.getMessage().contains(String.valueOf(value)))
          .isTrue();
    }
  }

        assertTrue(str.contains("dialectRevision="));
