Junit测试类BUG

例测试方法未写@Test

package com.guigu.test;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;/* *  * 測試dao層 * 推荐Spring的项目就可以使用Spring的单元测试，可以自动注入我们需要的组件 * 1.导入SpringTest模块 * 2.@ContextConfiguration指定Spring配置文件的位置 * 3.直接autowired要使用的组件即可 * */import com.guigu.bean.Department;import com.guigu.dao.DepartmentMapper;@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration(locations={"classpath:applicationContext.xml"})public class MapperTest {    @Autowired    DepartmentMapper departmentMapper;    /*     * 测试DepartmentMapper     * */    public void testCRUD(){        //1.创建SpringIOC容器        /*@SuppressWarnings("resource")        ApplicationContext ioc=new ClassPathXmlApplicationContext("applicationContext.xml");        ioc.getBean(DepartmentMapper.class);*/        System.out.println(departmentMapper);        //1.插入        departmentMapper.insertSelective(new Department(null,"开发部"));        departmentMapper.insertSelective(new Department(null,"测试部"));    }}

报错如下

修改：在测试方法前加@Test

@Testpublic void testCRUD(){...}
