实验04使用基本路径测试法求解自动售货机问题

1、实验报告实验序号：04 实验项目名称：使用基本路径测试法求解 “自动售货机”问题学号122姓名专业、班实验地点实1-511指导教师实验时间2013/4/27一、实验目的及要求l 理解基本路径覆盖测试法的概念和方法；l 掌握使用Eclipse+JUnit+EclEmma进行基本路径覆盖测试的方法。二、实验设备（环境）及要求l 开发环境：Eclipse v3.7及以上版本；JUnit v4.10及以上版本；文本编辑软件。 l 硬件要求：CPU PIV 以上，256M 内存，1G 硬盘空间。l 系统要求：Windows98/Me/XP/NT/2000，IE 5 以上。三、实验内容步骤1. 下载并安装

2、Eclipse+JUnit+EclEmma实验环境；2. 通读自动售货机程序，并在Eclipse环境下运行该程序；3. 使用基本路径测试法设计测试用例，完成以下表格；编号输入值Type输入值money状态预期输出实际情况001Beer5C各资源剩余Input Information Type: Beer; Money: 5 Cents; Change: 0Current StateBeer: 5Orange Juice: 65 Cents: 71 Dollar: 6002OrangeJuice5C各资源剩余Input Information Type: OrangeJuice; Money:

4、 Test Case文件SaleMachineTest.java:5、先点击运行看看，覆盖了33.1%：6、分析：红色代表未执行、黄色代表条件没有全部执行、绿色代表执行过了：7、继续修改测试代码，直到覆盖率达到100%：共编写了12个测试用例，使待测试代码100%被覆盖，运行如图：四、实验结果与数据处理a、最终待测试代码如下：public class SaleMachine private int countOfBeer, countOfOrangeJuice, countOfFiveCents, countOfOneDollar;private String typeOfGoods = &q
