实验：单元测试

1、精选优质文档-倾情为你奉上实验题目：单元测试实验目的：1、掌握Junit4的使用方法。2、能够使用Junit4进行简单的测试工作。3、熟悉EasyMock的使用。实验设备：主流PC机一套，Windows操作系统、Eclipse、Junit、EclEmma和EasyMock实验内容：1、使用Junit对ATMService 类中的方法进行单元测试。2、学习EasyMock的用法，写一个测试类TestATMServiceWithEMock进行测试。3、撰写单元测试实验报告。附件：/ATMService.javapackage atm;public class ATMService private
