我是靠谱客的博主坦率棒棒糖，最近开发中收集的这篇文章主要介绍第二天junit测试实例，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

NextDay源代码

package yanhongyun;

public class NextDay
{
    private int year;
    private int month;
    private int day;

    public NextDay()
    {
    }

    public NextDay(int year,int month,int day)
    {
      set(year,month,day);
    }

    public void set(int year,int month,int day)
    {
       if (year<0)
         this.year=0;
       else
         this.year=year;
       if (month<1 || month>12)
          this.month=1;
       else
          this.month=month;
       if (day<1 || day>lastDay(year,month))
          this.day=1;
       else
         this.day=day;
    }

    private int lastDay(int year,int month)
    {
       if (month==1 || month==3 || month==5 ||month==7 || month==8 || month==10||month==12)
       {
          return 31;
       }
       else if (month==2)
       {
          if ((year%4==0 && year%100!=0) || year %400==0)
            return 29;
          else
            return 28;
       }
       else
       {
          return 30;
       }
    }


    public NextDay  nextDay()
    {
       day=day+1;
       if (day>lastDay(year,month))
       {
          day=1;
          month=month+1;
          if (month>12)
          {
             month=1;
             year=year+1;
          }
       }
       return this;
    }
    public boolean equals(Object obj)
    {
       if (obj instanceof NextDay)
       {
          NextDay nd=(NextDay)obj;
          return (nd.year==this.year && nd.month==this.month && nd.day==this.day);
       }
       else
         return false;

    }
    public String tndString()
    {
       String str=year+"年"+month+"月"+day+"日";
       return str;
    }
}

Junit 测试程序

package yanhongyun;

import junit.framework.Assert;
import junit.framework.TestCase;

public class TestNextDay extends TestCase
{
   NextDay date1;
   NextDay date2;
   public TestNextDay(String name)
   {
      super(name);
   }
   public void setUp()
   {
   }
   public void testSet()
   {
      date1=new NextDay(2000,2,30);
      date2=new NextDay(2000,2,1);

      Assert.assertEquals(date2,date1);

   date1.set(1969,8,29);
      assertEquals(date1,date1);

      date1.set(1991,2,29);
      assertEquals(new NextDay(1991,2,1),date1);

   date1.set(-120,2,1);
   assertEquals(new NextDay(0,2,1),date1);

date1.set(-120,-2,-1);
assertEquals(new NextDay(0,1,1),date1);

   }
   public void testNextDay()
   {
      date1=new NextDay(1992,12,31);
      date2=new NextDay(1993,1,1);


      assertEquals(date2,date1.nextDay());

      date1.set(1992,2,28);

      date2.set(1992,2,29);

      assertEquals(date2,date1.nextDay());

      date1.set(1992,2,29);
      date2.set(1992,3,1);
      assertEquals(date2,date1.nextDay());

      date1.set(1998,2,28);
      date2.set(1998,3,1);
      assertEquals(date2,date1.nextDay());

      date1.set(1995,1,19);
      date2.set(1995,1,20);
      assertEquals(date2,date1.nextDay());

      date1.set(2006,1,31);
      date2.set(2006,2,1);
      assertEquals(date2,date1.nextDay());

      date1.set(2006,4,30);
      date2.set(2006,5,1);
      assertEquals(date2,date1.nextDay());

   }
   public static void main(String []args)
   {
      junit.textui.TestRunner.run(TestNextDay.class);
   }
}
