单元测试

1.pom.xml

<!--      单元测试-->

      <artifactId>spring-boot-starter-test</artifactId>
    </dependency>
  </dependencies>

3.service层测试

@RunWith(SpringRunner.class)
@SpringBootTest
public class TestUserService {

    private Logger log = LoggerFactory.getLogger(TestUserService.class);

    @Resource
    private UserService userService;

    @Before
    public void before(){
        log.info("test start");
    }
    @Test
    public void test(){
        System.out.println(userService.queryUserById(1));

    }
    @After
    public void after(){
        log.info("test end");
    }

}

4.controller层测试

@RunWith(SpringRunner.class)
@SpringBootTest
@AutoConfigureMockMvc
public class TestUserController {
    private Logger log = LoggerFactory.getLogger(TestUserController.class);
    @Autowired
    private MockMvc mockMvc;

    @Before
    public void before(){
        log.info("test start");
    }
    @Test
    public void test() throws Exception{
       MvcResult mvcResult = mockMvc.perform(MockMvcRequestBuilders.get("/user/1")).
               andExpect(MockMvcResultMatchers.status().isOk()).andReturn();

       log.info("响应状态" + mvcResult.getResponse().getStatus());
       log.info("响应内容" + mvcResult.getResponse().getContentAsString());
    }
    @After
    public void after(){
        log.info("test end");
    }
}
