junit 4パラメータ化テストとeasymockの使用

junit 4のいくつかの新しい特性を利用して、複数のパラメータを簡単にテストすることができます.次に、数値和を計算する例を挙げます.

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;  
/** 
 *  Parameterized  
 * 
 */  
@RunWith(Parameterized.class)  
public class AddTest3 {  
  
    private int input1;  
    private int input2;  
    private int expected;  
      
    /**

         1） Parameters  
         2） public static  
         3） Collection  
         4）  
         5）  
     * @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;  
    	}  
    }
}

 
junit 4とeasymockを組み合わせて、私は自分のコードのためにテストクラスを書きました.
