每当我在 Ant 中运行我的代码时，我都会遇到一个错误，但是在 Eclipse 上使用（Run > JunitTest）它运行良好，没有错误。
以下是我生成报告时收到的错误消息：
“测试类应该只有一个公共零参数构造函数”
java.lang.Exception：测试类在 java.lang.reflect.Constructor.newInstance(Unknown Source) 处应该只有一个公共零参数构造函数
“没有可运行的方法” -java.lang.Exception：java.lang.reflect.Constructor.newInstance 没有可运行的方法（未知来源）
请看我的代码：
此代码有注释 (@)
