1. Junit介绍

2. 使用Junit

1.导入依赖

  <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.12</version>
            <scope>test</scope>
        </dependency>

3. 常用注解

public class test {
    @Before
    public void before(){
        System.out.println("before");
    }
    @Test
    public void test(){
        System.out.println("test");
    }
    @After
    public void after(){
        System.out.println("after");
    }
}

4. 断言使用

Assert.assertEquals("Mike",byId.getName());
        Assert.assertEquals(888.88, byId.getMoney(), 0.0001);
        int a[]={1,2,3};
        Assert.assertArrayEquals(a,new int[]{1,2,3});
