5.1测试与 封装

1.结对伙伴：叶煜稳 博客：http://www.cnblogs.com/doubi2wy/

四则运算核心计算代码：

if(e.getSource()==B1){
String str=T1.getText();
num=Integer.parseInt(str);
}
for(int i=0;i<num;i++){
int m;
m=(int)(Math.random()*3+1);
if(e.getSource()==B2)
if(m==3){
a=(int)(Math.random()*100+1);
b=(int)(Math.random()*100+1);
T2.setText(a+"+"+"("+b+")=?");
result=a+b;
if(e.getSource()==B3){
num1=Integer.parseInt(T3.getText());
if(num1==result){
T4.setText("回答正确!!");
sum=sum+10;
}
else
{
T4.setText("回答错误!!!"+result);
}
}
}
else if(m==1){
q=(int)(Math.random()*100+1);
w=(int)(Math.random()*100+1);
T2.setText(q+"*"+"("+w+")"+"=?");
if(e.getSource()==B3){
num1=Integer.parseInt(T3.getText());
result1=q*w;
if(num1==result1){
T4.setText("回答正确!!");
sum=sum+10;
}
else
{
T4.setText("回答错误!!!"+result1);}
}
}
}
else if(m==2){
j=(int)(Math.random()*100+1);
k=(int)(Math.random()*100+1);
if(k==0)
k++;
T2.setText(j+"/"+"("+k+")"+"=?");
if(e.getSource()==B3){
num2=Double.parseDouble(T3.getText());
result2=(double)(j/k)*1.00;
if(num2==result2){
T4.setText("回答正确!!");
sum=sum+10;
}
else
{
T4.setText("回答错误!!!"+result2);}
}
}
}

}
}

将它封装成一个类：

package Junit4;
import java.util.Random;

public class test {
Random r=new Random();
private int result=0;
private double result1=0,result2=0;
private int m;
private int sum=0;
private int num=0;
private int num1=0;
private double num2=0;
private int a=0,b=0;
private int q=0,w=0;
private int j=0,k=0;
public int add(int a,int b)
{
a=r.nextInt()%100;
b=r.nextInt()%100;
System.out.println(a+"+"+"("+b+")=?");
result=a+b;
return result;
}
public double Cheng(int q,int w)
{
q=r.nextInt()%100;
w=r.nextInt()%100;
System.out.println(q+"*"+"("+w+")"+"=?");
result1=q*w;
return result1;
}
public double Chu(int j,int k)
{
j=r.nextInt()%100;
k=r.nextInt()%100;
if(k==0)
k++;
System.out.println(j+"/"+"("+k+")"+"=?");
return result2;
}
/**
* @param args
*/
public static void main(String[] args) {
test Jia=new test();
Jia.add(1, 1);
test cheng=new test();
cheng.Cheng(2,3);
test chu=new test();
chu.Chu(3,0);

}

}

package Junit4test;

import static org.junit.Assert.*;

import org.junit.Test;
import Junit4.test;
public class TTest {

@Test
public void testAdd() {
int z=new test().add(1,1);
assertEquals(2,z);
}

@Test
public void testCheng() {
double z=new test().Cheng(2,3);
assertEquals(6,(int)z);
}

@Test
public void testChu() {
double z=new test().Chu(3,0);
assertEquals(3,(int)z);
}

}



单元测试还需要什么！！！
