junit4的参数测试

junit4的参数测试

当一个方法需要多次测试时可以用junit4的参数化的测试，详细说明见参考

这里写个方法多参数的例子

-------》HelloWorld

public class HelloWorld {
    public  int add(int i,int j){
    	return i+j;
    } 
}

-----》HelloWorldTest

package com.xx.test;

import static org.junit.Assert.assertEquals;

import java.util.Arrays;
import java.util.Collection;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.junit.runners.Parameterized;
import org.junit.runners.Parameterized.Parameters;

@RunWith(value=Parameterized.class)
public class HelloWorldTest {
 
    private long expected;
    private int[] value;
 
   @Parameters
    public static Collection data() {
        return Arrays.asList( new Object[][] {
        					{ 5, new int[]{1,3} },
        					{ 5040, new int[]{1,3} },
        					{ 2, new int[]{1,3} },
        					{ 4, new int[]{1,3} }
                             });
    }
 
    public HelloWorldTest(long expected, int[] value) {
        this.expected = expected;
        this.value = value;
    }
 
    @Test
    public void addTest() {
    	HelloWorld hw = new HelloWorld();
        assertEquals("不相等",expected, hw.add(value[0], value[1]));
        
    }
}
