如何使用junit 4将开关/案例代码重写为junit 5或testng

Question

我有代码：

Result result = null;
    for(int i = 1; i <= setOfConfiguration; i++){

        switch(typeOfAgreement){
                case "GUS":
                    result = JUnitCore.runClasses(first.class); break;
                case "MUS":
                    result = JUnitCore.runClasses(second.class); break;
                case "DUS":
                    result = JUnitCore.runClasses(third.class); break;
        }
      }
