JUnit测试框架的使用(含测试用例)

1、软件测试实验报告计算机2010-1 姓名：周杰 学号：3100717102JUnit测试框架的使用【实验目的】1、掌握Junit测试框架的使用2、掌握测试用例的编写【实验环境】操作系统：Windows 7 （x64）浏览器：IE 9开发环境：Eclipse IDE for Java DevelopersA：Junit使用方法示例1查看运行结果：B：Junit使用方法示例21）在工程中添加类：2）写单元测试代码：3）进一步完善测试用例：4）查看分析运行结果，修改错误代码：改进后的方法：wordFormat4DBpublic static String wordFormat4DB(String n

2、ame)if(name = null)return null;Pattern p = Ppile("A-Z");Matcher m = p.matcher(name);StringBuffer sb = new StringBuffer();while(m.find()if(m.start() != 0)m.appendReplacement(sb, ("_"+m.group().toLowerCase();return m.appendTail(sb).toString().toLowerCase();修改后测试用例运行成功：实验2【实验目的】1、掌握

3、Junit测试框架的使用2、掌握测试用例的编写【实验环境】操作系统：Windows 7 （x64）浏览器：IE 9开发环境：Eclipse IDE for Java Developers【程序清单】package zhoujie; public class Date public Date() public Date(int year, int month, int day) super(); if (this.isDayValid(year, month, day) && this.isMonthValid(month) && this.isYearValid

13、 break; case 10: sum = 274; break; case 11: sum = 305; break; case 12: sum = 335; break; default: System.out.print("data error"); break; else switch (date.getMonth() case 1: sum = 0; break; case 2: sum = 31; break; case 3: sum = 59; break; case 4: sum = 90; break; case 5: sum = 120; break;
