テスト日時のユーティリティutility

Question

JUnitのテストではかなり新しいので、Javaプログラミングのバックグラウンドは堅実ではありません。私はテストを正しく動かせるように専門家が必要です。私はあなたに私のパラメータに焦点を当てて欲しいですが、それより良い提案があればそれを試してみて欲しいです。私はordinalDate()のためだけに、テストを実行する必要があります、ありがとう。

Answer 1

パラメータのリストの各エントリは、3つの数字の配列であります

Object input[][] = { 
     {3, 16, 1993}, 
     {6, 24, 1997}, 
     {9, 8, 1995} 
}; 

あなたのテストクラスのコンストラクタは4パラメータを必要とします。

public DateUtilityTest(int input, int month, int day, int year) 

inputの値はありません。したがって、テストは実行されません。
