junit4參數化測試和easymock的使用

系統 1755 0
利用junit4的一些新特性，我們可以方便的對多個參數進行測試，下面舉一個計算數值和的例子： 
      package com.test.junit4;

import java.util.Arrays;  
import java.util.Collection;  
  
import org.junit.Assert;  
import org.junit.Test;  
import org.junit.runner.RunWith;  
import org.junit.runners.Parameterized;  
import org.junit.runners.Parameterized.Parameters;  
/** 
 * 參數化測試的類必須有Parameterized測試運行器修飾 
 * 
 */  
@RunWith(Parameterized.class)  
public class AddTest3 {  
  
    private int input1;  
    private int input2;  
    private int expected;  
      
    /** 
     * 準備數據。數據的準備需要在一個方法中進行，該方法需要滿足一定的要求： 
 
         1）該方法必須由Parameters注解修飾 
         2）該方法必須為public static的 
         3）該方法必須返回Collection類型 
         4）該方法的名字不做要求 
         5）該方法沒有參數 
     * @return 
     */
    @Parameters  
    @SuppressWarnings("unchecked")  
    public static Collection prepareData(){  
        Object [][] object = {{-1,-2,-3},{0,2,2},{-1,1,0},{1,2,3}};  
        return Arrays.asList(object);
    }  
    
    public AddTest3(int input1,int input2,int expected){  
        this.input1 = input1;  
        this.input2 = input2;  
        this.expected = expected;  
    }  
    @Test  
    public void testAdd(){  
        Add add = new Add();  
        int result = add.add(input1, input2);  
        Assert.assertEquals(expected,result);  
    }  
    
    class Add{
    	public int add(int a,int b){  
    		return a+b;  
    	}  
    }
}

結合junit4和easymock，我自己為我的代碼寫了一個測試類：
?我的原程序是一個從HttpServletRequest獲得參數，計算結果后用socke發送一個請求然后再接受一個請求，代碼如下： 
      package com.movellsoft.ideal.manufacturer.diagnostics.web;

? 利用easymock和參數化測試，我寫的一個測試類：
