在IDEA中打开要测试的类，使用ctrl + shift + T 新建一个测试类，选择要测试的方法

package cn.edu.shu.ces_chenjie.service;import cn.edu.shu.ces_chenjie.pojo.Person;import org.junit.Assert;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.boot.test.context.SpringBootTest;import org.springframework.test.context.junit4.SpringRunner;@RunWith(SpringRunner.class)@SpringBootTestpublic class PersonServiceTest {    @Autowired    private PersonService personService;    @Test    public void insertTwo() throws Exception {    }    @Test    public void getAge() throws Exception {    }    @Test    public void getOne() throws Exception {        Person person = personService.getOne(1);        Assert.assertEquals(new Integer(1),person.getId());    }}

如何测试Rest接口？

package cn.edu.shu.ces_chenjie.controller;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc;import org.springframework.boot.test.context.SpringBootTest;import org.springframework.test.context.junit4.SpringRunner;import org.springframework.test.web.servlet.MockMvc;import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;import org.springframework.test.web.servlet.result.MockMvcResultMatchers;import static org.junit.Assert.*;@RunWith(SpringRunner.class)@SpringBootTest@AutoConfigureMockMvcpublic class PersonControllerTest {    @Autowired    private MockMvc mockMvc;    @Test    public void personList() throws Exception {        mockMvc.perform(MockMvcRequestBuilders.get("/persons"))                .andExpect(MockMvcResultMatchers.status().isOk());    }}

使用mvn clean package构建项目时会自动运行所有单元测试，如果想跳过，则在其后加上 -Dmaven .test.skip=true
