专业、班实验时间一、实验目的及要求掌握在Eclipse环境下JUnit单元测试工具的安装和使用方法；针对一个实诘问题，在JUnit环境下设计并履行测试用例。二、实验要求开发环境：Eclipsev3.7及以上版本；JUnitv4.10及以上版本；文本编写软件。硬件要求：CPUPIV以上，256M内存，1G硬盘空间。系统要求：Windows98/Me/XP/NT/2000，IE5以上。三、实验内容与步骤下载并安装JDK下载并安装Eclipse下载并安装JUnit通读自动售货机程序，并在Eclipse环境下运转该程序在JUnit环境下履行以下表格中的测试用例，并填写完成该表格。编输入值输入值状态预期输出实质情号Typemoney况001Beer5C各资InputInformation源剩Type:Beer;Money:5Cents;Change:0余CurrentStateBeer:5OrangeJuice:65Cents:71Dollar:6002OrangeJuice5C各资InputInformation源剩Type:OrangeJuice;Money:5Cents;Change:0余CurrentStateBeer:6OrangeJuice:55Cents:71Dollar:6003Beer1D没有FailureInformation啤酒BeerShortage提交测试用例程序和该程序运转结果最后画面。总结本次试验，并撰写实验报告。四、实验结果与数据办理编输入值输入值状态号Typemoney001Beer5C各资源剩余002OrangeJuice5C各资源剩余003Beer1D没有啤酒

实质情况与预期值一致与预期值一致与预期值有偏差实验环境变量配置。配置完成后检查能否正确，再cmd输入java–version，java后要有空格，结果以下列图，即配置环境变量正确。测试用例程序importstaticorg.junit.Assert.*;importorg.junit.Before;importorg.junit.Test;publicclassSaleMachineTest{SaleMachinesaleMachine=newSaleMachine();@BeforepublicvoidsetUp()throwsException{}@TestpublicvoidtestOperation1(){StringexpectedResult="FailureInformation\n"+"Type:Beer;Money:5Cents;Change:0\n\n"+"CurrentState\n"+"Beer:5\n"+"OrangeJuice:6\n"+"5Cents:7\n"+"1Dollar:6";assertEquals(expectedResult,saleMachine.operation("Beer","5C"));}}结果测试用例程序importstaticorg.junit.Assert.*;importorg.junit.Before;importorg.junit.Test;publicclassSaleMachineTest{SaleMachinesaleMachine=newSaleMachine();@BeforepublicvoidsetUp()throwsException{}@TestpublicvoidtestOperation1(){StringexpectedResult="InputInformation\n"+"Type:Beer;Money:5Cents;Change:0\n\n"+"CurrentState\n"+"Beer:5\n"+"OrangeJuice:6\n"+"5Cents:7\n"+"1Dollar:6";assertEquals(expectedResult,saleMachine.operation("OrangeJuice","5C"));}}结果测试用例程序importstaticorg.junit.Assert.*;importorg.junit.Before;importorg.junit.Test;publicclassSaleMachineTest{SaleMachinesaleMachine=newSaleMachine();@BeforepublicvoidsetUp()throwsException{}@TestpublicvoidtestOperation1(){StringexpectedResult="FailureInformation\n"+"BeerShortage";assertEquals(expectedResult,saleMachine.operation("Beer","1D"));}}结果五、解析与议论六、教师考语成绩署名：日期：附录问题描绘自动售货机程序：若投入5角钱或1元钱的硬币，按下“橙汁”或“啤酒”按钮，则相应的饮料就送出来；若售货机没有零钱找，则显示“零钱找完”的红灯亮，这是再投入一元硬币并按下按钮后，饮料不送出来并且1元硬币也退出来；如有零钱找，则显示“零钱找完”的红灯灭，在送出饮料的同时退还5角硬币。程序流程图实验源代码（出缺点的源代码）publicclassSaleMachine{privateintcountOfBeer,countOfOrangeJuice,countOfFiveCents,countOfOneDollar;privateString[]typeOfGoods={"Beer","OrangeJuice"};privateStringresultOfDeal;publicSaleMachine(){initial();}publicvoidinitial(){countOfBeer=6;countOfOrangeJuice=6;countOfFiveCents=6;countOfOneDollar=6;}publicSaleMachine(intfiveCents,intoneDollar,intnumOfBeer,intnumOfOrange)便于测试的初始化函数{countOfFiveCents=fiveCents;countOfOneDollar=oneDollar;countOfBeer=numOfBeer;countOfOrangeJuice=numOfOrange;}publicStringcurrentState(){Stringstate="CurrentState\n"+"Beer:"+countOfBeer+"\n"+"OrangeJuice:"+countOfOrangeJuice+"\n"+"5Cents:"+countOfFiveCents+"\n"+"1Dollar:"+countOfOneDollar;returnstate;}publicStringoperation(Stringtype,Stringmoney)//type是用户选择的产品，money是用户投币种类{if(money.equalsIgnoreCase("5C"))//假如用户投入5角钱{if(type.equals(typeOfGoods[0])){
