專業(yè)、班實驗時間一、實驗目的及要求掌握在Eclipse環(huán)境下JUnit單元測試工具的安裝和使用方法；針對一個實詰問題，在JUnit環(huán)境下設計并履行測試用例。二、實驗要求開發(fā)環(huán)境：Eclipsev3.7及以上版本；JUnitv4.10及以上版本；文本編寫軟件。硬件要求：CPUPIV以上，256M內存，1G硬盤空間。系統(tǒng)要求：Windows98/Me/XP/NT/2000，IE5以上。三、實驗內容與步驟下載并安裝JDK下載并安裝Eclipse下載并安裝JUnit通讀自動售貨機程序，并在Eclipse環(huán)境下運轉該程序在JUnit環(huán)境下履行以下表格中的測試用例，并填寫完成該表格。編輸入值輸入值狀態(tài)預期輸出實質情號Typemoney況001Beer5C各資InputInformation源剩Type:Beer;Money:5Cents;Change:0余CurrentStateBeer:5OrangeJuice:65Cents:71Dollar:6002OrangeJuice5C各資InputInformation源剩Type:OrangeJuice;Money:5Cents;Change:0余CurrentStateBeer:6OrangeJuice:55Cents:71Dollar:6003Beer1D沒有FailureInformation啤酒BeerShortage提交測試用例程序和該程序運轉結果最后畫面。總結本次試驗，并撰寫實驗報告。四、實驗結果與數據辦理編輸入值輸入值狀態(tài)號Typemoney001Beer5C各資源剩余002OrangeJuice5C各資源剩余003Beer1D沒有啤酒

實質情況與預期值一致與預期值一致與預期值有偏差實驗環(huán)境變量配置。配置完成后檢查能否正確，再cmd輸入java–version，java后要有空格，結果以下列圖，即配置環(huán)境變量正確。測試用例程序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"));}}結果測試用例程序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"));}}結果測試用例程序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"));}}結果五、解析與議論六、教師考語成績署名：日期：附錄問題描繪自動售貨機程序：若投入5角錢或1元錢的硬幣，按下“橙汁”或“啤酒”按鈕，則相應的飲料就送出來；若售貨機沒有零錢找，則顯示“零錢找完”的紅燈亮，這是再投入一元硬幣并按下按鈕后，飲料不送出來并且1元硬幣也退出來；如有零錢找，則顯示“零錢找完”的紅燈滅，在送出飲料的同時退還5角硬幣。程序流程圖實驗源代碼（出缺點的源代碼）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)便于測試的初始化函數{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是用戶選擇的產品，money是用戶投幣種類{if(money.equalsIgnoreCase("5C"))//假如用戶投入5角錢{if(type.equals(typeOfGoods[0])){
