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
