![在这里插入图片描述][4805406ee1e14dffae722b4dec0038b8.png]

#### @Test注解 ####

import org.junit.Test;
    
    import static org.junit.Assert.*;
    
    public class StudentOperationMySqlImplTest {
        
        IStudentDAO studentDAO = (IStudentDAO) DAOFactory.newInstance("IStudentDAO");
    
        @Test//@Test注解
        public void addStudent() {
        
            Student student = new Student(1007l, "赵六", 17, "女", DateUtils.strToUtil("2002-02-13"), "北京市海淀区");
            assertEquals(new Integer(1),studentDAO.addStudent(student));//断言测试
        }
        }

除此之外，还有@Before（每一个测试方法调用前必执行的方法）等注解

#### Springboot ####

在Springboot2.2之前，集成了Junit4(之后是junit5)

<dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-test</artifactId>
                <scope>test</scope>
            </dependency>

##### Service层 #####

@RunWith(SpringRunner.class)
    @SpringBootTest
    public class LearnServiceTest {
        
    
        @Autowired
        private LearnService learnService;
        
        @Test
        public void getLearn(){
        
            LearnResource learnResource=learnService.selectByKey(1001L);
            Assert.assertThat(learnResource.getAuthor(),is("博客"));
        }
    }

##### Controller层 #####

MockMvc实现了对Http请求的模拟

@RunWith(SpringRunner.class)
    @SpringBootTest
    
    public class LearnControllerTest {
        
        @Autowired
        private WebApplicationContext wac;
    
        private MockMvc mvc;
        
    
    
        @Before
        public void setupMockMvc(){
        
            mvc = MockMvcBuilders.webAppContextSetup(wac).build(); //初始化MockMvc对象
            
        }
    
        /**
         * 新增教程测试用例
         * @throws Exception
         */
        @Test
        public void addLearn() throws Exception{
        
            String json="{\"author\":\"HAHAHAA\",\"title\":\"Spring\",\"url\":\"http://tengj.top/\"}";
            mvc.perform(MockMvcRequestBuilders.post("/learn/add")
                        .accept(MediaType.APPLICATION_JSON_UTF8)
                        .content(json.getBytes()) //传json参数
                        .session(session)
                )
               .andExpect(MockMvcResultMatchers.status().isOk())
               .andDo(MockMvcResultHandlers.print());
        }
        }

### Junit4和Junit5的区别 ###

*  忽略测试用例执行
 *  RunWith 配置
 *  @Before、@BeforeClass、@After、@AfterClass 被替换

### Junit5 ###

#### SpringBoot ####

在Springboot2.2之后，集成了Junit5

##### Controller层 #####

@SpringBootTest
    class UploadFileControllerTest {
        
        @Autowired
        private UploadFileController fileController;
    
        @Test
        void getFileList() throws Exception {
        
            Result result = fileController.getFileList();
            System.out.println(result);
    
        }
    
    }

或者

@SpringBootTest
    class UploadFileControllerTest {
        
        @Autowired
        private WebApplicationContext wac;
    
        private MockMvc mockMvc;
    
        @BeforeEach
        void init() {
        
            mockMvc = MockMvcBuilders.webAppContextSetup(wac).alwaysDo(print()).build();
        }
    
        @Test
        void getFileList() throws Exception {
        
            mockMvc.perform(get("/fileList")).andExpect(status().isOk());
        }
        
    
    }

或者

@SpringBootTest
    @AutoConfigureMockMvc
    class UploadFileControllerTest {
        
        @Autowired
        private MockMvc mockMvc;
        
        @Test
        void getFileList() throws Exception {
        
            mockMvc.perform(get("/fileList")).andExpect(status().isOk());
        }
        
    }

##### Service层/dao层 #####

一般是对接口进行测试

@SpringBootTest
    class FileMapperTest {
        
        @Autowired
        private FileMapper fileMapper;
    
        @Test
        void selectFileList() {
        
            List<FilePO> filePOS = fileMapper.selectFileList();
            for (FilePO filePO : filePOS) {
        
                System.out.println(filePO);
            }
        }
    }
