姓名：

指导老师：

一、实验题目

编制并运行JUnit测试用例程序

二、实验内容

●基于JUnit实现白盒测试用例

●记录测试结果，截屏或文字

三、实验步骤

3.1NetBeans开发环境中建立第一个Junit测试程序，测试数据库的连接如图示正在下载Junit测试插件

3.2Junit测试插件安装好后，建立数据库测试程序，运行结果如下图：

3.3数据库连接测试成功截图如下：

数据库测试程序源代码：

（对应DatabaseConn.java）

packagecom.ustc.biz;

importjava.sql.Connection;

importjunit.framework.TestCase;

publicclassDatabaseConnJUnitTestextendsTestCase{

publicDatabaseConnJUnitTest（StringtestName）{

super（testName）;

}

protectedvoidsetUp（）throwsException{

System.out.println（"测试开始"）;

}

protectedvoidtearDown（）throwsException{

System.out.println（"测试结束"）;

}

publicvoidtestGetConnection_0args（）throwsException{

System.out.println（"getConnection"）;

System.out.println（"------------------------------------"）;

ConnectionexpResult=null;

Connectionresult=DatabaseConn.getConnection（）;

assertEquals（expResult,result）;

System.out.println（result.toString（））;

//TODOreviewthegeneratedtestcodeandremovethedefaultcalltofail.

fail（"Thetestcaseisaprototype."）;

}

publicvoidtestGetConnection_3args（）throwsException{System.out.println（"——————————————getConnection——————————————"）;

Stringuserid="root";

Stringpwd="123456";

StringconnectURL="jdbc:

mysql:

//localhost:

3306/schadmin?

useUnicode=true&characterEncoding=UTF-8";

ConnectionexpResult=null;

Connectionresult=DatabaseConn.getConnection（userid,pwd,connectURL）;

assertEquals（expResult,result）;

System.out.println（"——————————————getConnection——————————————"）;

//TODOreviewthegeneratedtestcodeandremovethedefaultcalltofail.

fail（"Thetestcaseisaprototype."）;

}

publicvoidtestMain（）{

System.out.println（"main"）;

System.out.println（"——————————————mainStart——————————————"）;

String[]agrs=null;

System.out.println（"——————————————mainEnd——————————————"）;

//TODOreviewthegeneratedtestcodeandremovethedefaultcalltofail.

fail（"Thetestcaseisaprototype."）;

}

}

3.4学生成绩添加测试程序出现空指针异常

错误原因：

编写测试用例期间，对象定义时未申请空间

根据错误提示：

解除引用空值指针

正确的修改方案：

GradeVOgradeVO=null;GradeVOgradeVO=newGradeVO（）;

测试程序运行成功！

3.5运行编写的测试用例，发现学生的成绩可以添加为负数等，功能异常
