MuJava简洁
µJava (muJava) 是 Java 程序的变异系统。 它自动生成用于传统突变测试和类级别突变测试的突变体。 µJava 可以测试单个类和多个类的包。 用户以对封装在单独 JUnit 类的方法中的被测类的方法调用序列的形式提供测试。

(共计16个方法级别的变异算子)
一共有3个操作:replace, delete, and insert
针对6类基本运算符:(1) arithmetic operator, (2) relational operator, (3) conditional operator, (4) shift operator, (5) logical operator, and (6) assignment
产生了7类变异算子
