软件测试实验报告--实验三班级： 学号：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）package;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，功能异常学生成绩管理Junit测试源代码：（对应GradeMgr.java）package;importcom.ustc.vo.GradeVO;importjava.util.ArrayList;importjunit.framework.TestCase;publicclassGradeMgrJUnitTestextendsTestCase{publicGradeMgrJUnitTest(StringtestName){super(testName);}protectedvoidsetUp()throwsException{System.out.println("测试开始");}protectedvoidtearDown()throwsException{System.out.println("测试结束");}publicvoidtestAddGrade()throwsException{System.out.println("addGrade");GradeVOgradeVO=null;gradeVO.setStuID("20131601");gradeVO.setNumElectron(60);gradeVO.setNumSoftware(80);gradeVO.setNumSecurity(60);gradeVO.setNumJava(60);gradeVO.setNumDB(80);gradeVO.setNumImage(60);gradeVO.setNumDistributed(60);gradeVO.setNumTest(80);GradeMgrinstance=newGradeMgr();instance.addGrade(gradeVO);fail("Thetestcaseisaprototype.");}publicvoidtestUpdateGrade()throwsException{System.out.println("updateGrade");GradeVOgradeVO=null;gradeVO.setStuID("20131601");gradeVO.setNumElectron(90);gradeVO.setNumSoftware(90);gradeVO.setNumSecurity(90);gradeVO.setNumJava(90);gradeVO.setNumDB(90);gradeVO.setNumImage(90);gradeVO.setNumDistributed(90);gradeVO.setNumTest(90);GradeMgrinstance=newGradeMgr();instance.updateGrade(gradeVO);fail("Thetestcaseisaprototype.");}publicvoidtestDeleteGradeList()throwsException{System.out.println("deleteGradeList");StringSTUID="20131601";GradeMgrinstance=newGradeMgr();instance.deleteGradeList(STUID);fail("Thetestcaseisaprototype.");}publicvoidtestGetAllStudentsGrade()throwsException{System.out.println("getAllStudentsGrade");GradeMgrinstance=newGradeMgr();ArrayListexpResult=null;ArrayListresult=instance.getAllStudentsGrade();if(result==null){System.out.println("—————————————空—————————————");}assertEquals(expResult,result);fail("Thetestcaseisaprototype.");}publicvoidtestGetGradeByStudentID()throwsException{System.out.println("getGradeByStudentID");Stringstuid="20131601";GradeMgrinstance=newGradeMgr();GradeVOexpResult=null;GradeVOresult=instance.getGradeByStudentID(stuid);assertEquals(expResult,result);fail("Thetestcaseisaprototype.");}publicvoidtestGetSearchStudentsGrade()throwsException{System.out.println("getSearchStudentsGrade");intsearchkey=60;//及格GradeMgrinstance=newGradeMgr();ArrayListexpResult=null;ArrayListresult=instance.getSearchStudentsGrade(searchkey);assertEquals(expResult,result);fail("Thetestcaseisaprototype.");}publicvoidtestGetFirstStudentsGrade()throwsException{System.out.println("getFirstStudentsGrade");intsearchkey=100;GradeMgrinstance=newGradeMgr();ArrayListexpResult=null;ArrayListresult=instance.getFirstStudentsGrade(searchkey);assertEquals(expResult,result);fail("Thetestcaseisaprototype.");}publicvoidtestGetSearchStudentsGradebyID()throwsException{System.out.println("getSearchStudentsGradebyID");Stringsearchkey="20131601";GradeMgrinstance=newGradeMgr();ArrayListexpResult=null;ArrayListresult=instance.getSearchStudentsGradebyID(searchkey);assertEquals(expResult,result);fail("Thetestcaseisaprototype.");}publicvoidtestDeleteGrade()throwsException{System.out.println("deleteGrade");StringSTUID="20131601";GradeMgrinstance=newGradeMgr();instance.deleteGrade(STUID);fail("Thetestcaseisaprototype.");}publicvoidtestDeleteAllGrade()throwsException{System.out
