Junit程序测试——小白自学

Junit程序测试——学习笔记

程序测试Junit是Java自动化测试工具借助Maven可以帮助做好所有的测试案例 下面是判断是否是闰年的代码

runnianjude.class

public class runnianjude { public static boolean judge(int a) { if(a<0||a>10000) return false; else { if(a%100!=0&&a%4==0) return true; else { if(a%100==0&&a%400==0) return true; else return false; } } } }

Junittest.class

import static org.junit.Assert.*;//导入Assert中所有的静态类的方法 import org.junit.Test; public class Junittest { @Test public void test() { assertEquals(false,new runnianjude().judge(-100)); assertEquals(true,new runnianjude().judge(2020)); assertEquals(false,new runnianjude().judge(2017)); } }

pom.xml中插入下面一段代码实现下载Junit包
