Springの自動構成レポートをテストで有効にする方法は？

Question

私はSpringにデバッグモードがあることを知りました。このモードでは、自動設定に関する洞察が得られます。サーバーの場合、アプリケーションパラメータとして--debugを渡すことで有効にすることができます。

（SpringJUnit4ClassRunnerで実行される）テストにもデバッグモードを有効にする方法はありますか？

自動構成レポートが動作している場合、それはこのようないくつかの出力を印刷する必要があります：

--debugは、自動コンフィギュレーションレポートに切り替えdebugプロパティを設定します。たとえば、テストクラスで@TestPropertySourceを使用して同じテストを行うことができます。

@RunWith(SpringJUnit4ClassRunner.class) 
@SpringApplicationConfiguration(Application.class) 
@TestPropertySource(properties = "debug=true") 
public class YourTests { 
    // … 
}
