}这个类不知道如何用Junit测试···等我再学习一下再来修改···
package cn.zheng;

import static org.junit.Assert.*;

import org.junit.After;
import org.junit.Before;
import org.junit.Test;

public class TestSushu {

    private Sushu ss;
    @Before
    public void setUp() throws Exception {
        ss=new Sushu();
    }

    @After
    public void tearDown() throws Exception {
        
    }

    @Test
    public void test() {
        int []b = new int[2];
        b[0]=34;
        b[1]=2;
        ss=new Sushu(b);
        ss.run();
        
        b=null;
        ss=new Sushu(b);
        ss.run();
        
        b=new int[2];
        b[0]=2;
        b[1]=34;
        ss=new Sushu(b);
        ss.run();
        
        b[0]=-35;
        b[1]=3;
        ss=new Sushu(b);
        ss.run();
    
    }

}



测试用例:第一个数:   3       6 第二个数:6  结果为6

      第一个数:                        结果为数据不合法

      第一个数:-3 第二个数:34    结果为1

      第一个数:     a  v c            结果为数据不合法
