实验：单元测试

实验题目：单元测试实验目的：1、掌握Junit4的使用方法。2、能够使用Junit4进行简单的测试工作。3、熟悉EasyMock的使用。实验设备：主流PC机一套，Windows操作系统、Eclipse、Junit、EclEmma和EasyMock实验内容：1、使用Junit对ATMService 类中的方法进行单元测试。2、学习EasyMock的用法，写一个测试类TestATMServiceWithEMock进行测试。3、撰写单元测试实验报告。附件：/ATMService.javapackage atm;public class ATMService private IDataConnection dconn;public ATMService(IDataConnection dc)dconn=dc;/取款操作public void withdraw(String cardNo,int amount)AccountInfo a=dconn.getAccount(cardNo);int balance=a.getBalance()-amount;a.setBalance(balance);dconn.updateAccount(a);/存款操作public void deposit(String cardNo,int amount)AccountInfo a=dconn.getAccount(cardNo);int balance=a.getBalance()+amount;a.setBalance(balance);dconn.updateAccount(a);/转账操作public void transfer(String fromCardNo,String toCardNo,int amount)AccountInfo a=dconn.getAccount(fromCardNo);AccountInfo b=dconn.getAccount(toCardNo);int aBalance=a.getBalance()-amount;int bBalance=b.getBalance()+amount;a.setBalance(aBalance);b.setBalance(bBalance);dconn.updateAccount(a);dconn.updateAccount(b); /查询操作public int inquiry(String cardNo)AccountInfo a=dconn.getAccount(cardNo);return a.getBalance();/IDataConnection.javapackage atm;public interface IDataConnection public AccountInfo getAccount(String id);public void updateAccount(AccountInfo account);public void addAccount(AccountInfo account);/AccountInfo.javapackage atm;public class AccountInfo private String cardNo;private String password;private int balance;public AccountInfo(String c, String p, int b) cardNo = c;password = p;balance = b;public String getCardNo() return cardNo;public void setCardNo(String cardNo) this.cardNo = cardNo;public String getPassword() return password;public void setPassword(String password) this.password = password;public int getBalance() return balance;public void setBalance(int balance) this.balance = balance;/MockDataConnection.javapackage atm;import java.util.HashMap;public class MockDataConnection implements IDataConnection private HashMap mdb;public MockDataConnection() mdb = new HashMap();AccountInfo a = new AccountInfo(1, 111111, 300);AccountInfo b = new AccountInfo(2, 222222, 1000);mdb.put(a.getCardNo(), a);mdb.put(b.getCardNo(), b);/ Overridepublic AccountInfo getAccount(String id) / TODO Auto-generated method stubreturn mdb.get(id);/ Overridepublic void updateAccount(AccountInfo account) / TODO Auto-generated method stubaddAccount(account);/ Overridepublic void addAccount(AccountInfo account) / TODO Auto-generated method stubmdb.put(account.getCardNo(), account);/TestATMService.javapackage atm;import static org.junit.Assert.*;import org.junit.Test;public class TestATMService private IDataConnection mdc = new MockDataConnection();private ATMService atm = new ATMService(mdc);Testpublic void testWithdraw() atm.withdraw(1, 20);AccountInfo a = mdc.getAccount(1);assertEquals(280, a.getBalance();Testpublic void testDeposit() atm.deposit(1, 20);AccountInfo a = mdc.getAccount(1);assertEquals(320, a.getBalance();Testpublic void testTransfer() atm.transfer(2, 1, 200);AccountInfo a = mdc.getAccount(1);Accou
