3. spring boot——MockMvc的用法

本篇避免长篇大论,依次说明:依赖、测试dao或service、测试controller、说明事项、附源码。

  1、依赖

复制代码
<dependency>
  <groupId>junit</groupId>
  <artifactId>junit</artifactId>
  <version>4.12</version>
  <scope>test</scope> 
</dependency>
<dependency>
  <groupId>com.jayway.jsonpath</groupId>
  <artifactId>json-path</artifactId>
  <version>2.2.0</version>
</dependency>
<dependency>
  <groupId>org.springframework</groupId>   <artifactId>spring-test</artifactId>   <version>5.1.0.RELEASE</version> </dependency>

 <dependency>
     <groupId>org.hamcrest</groupId>
     <artifactId>hamcrest-core</artifactId>
     <version>1.3</version>
     <scope>test</scope>
</dependency>

  2、测试dao、service

复制代码
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:spring-context.xml"})
public class ArticleServiceDaoTest2 {

    @Autowired
    private ArticleDao articleDao;
    
    @Test
    public void getAllListTest() {
        List<Article> list=articleDao.getAllList();
        for(Article article:list) {
            System.out.println(article.getContent());
        }
    }
    
    @Test
    @Transactional
    public void addTest() {
        Article article = new Article();
        article.setClassify("2");
        article.setTitle("标题");
        article.setContent("内容");
        articleDao.insert(article);
    }
    
    @Test
    public void addTest2() {
        Article article = new Article();
        article.setClassify("2");
        article.setTitle("标题");
        article.setContent("内容");
        articleDao.insert(article);
    }
}
复制代码

  3、测试controller

复制代码
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:spring-context.xml","classpath:spring-mvc.xml"})
@WebAppConfiguration
public class ArticleControllerTest {

    @Autowired
    private WebApplicationContext webApplicationContext;
    protected MockMvc mockMvc;
    
    @Before
    public void setup(){
        //加载web容器上下文
        mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
    }
    
    //返回json串
    @Test
    public void getByIdTest() throws Exception {
        mockMvc.perform(MockMvcRequestBuilders.get("/article/getById")
                .param("id", "15")
                .accept(MediaType.APPLICATION_JSON))
                .andExpect(MockMvcResultMatchers.status().isOk())
                .andExpect(MockMvcResultMatchers.content().contentTypeCompatibleWith(MediaType.APPLICATION_JSON))
                .andExpect(MockMvcResultMatchers.jsonPath("$.id").value(15))
                .andExpect(MockMvcResultMatchers.jsonPath("$.content").value("123456"))
                .andDo(MockMvcResultHandlers.print())
                .andReturn();
    }
    
    //返回视图
    @Test
    public void detailTest() throws Exception {
        MvcResult result = mockMvc.perform(MockMvcRequestBuilders.get("/article/detail").param("id", "15"))
                .andExpect(MockMvcResultMatchers.view().name("page/detail"))
                .andExpect(MockMvcResultMatchers.status().isOk())
                .andDo(MockMvcResultHandlers.print())
                .andReturn();    
        Assert.assertNotNull(result.getModelAndView().getModel().get("article"));
    }
    
    //添加实体
    @Test
    public void addTest() throws Exception {
        ResultActions resultActions = mockMvc.perform(
                 MockMvcRequestBuilders
                 .get("/article/add")//开始的斜杠不能丢,否则404
                 .contentType(MediaType.APPLICATION_FORM_URLENCODED)
                 .param("title", "测试用户1")
                 .param("classify", "123456")
                 .param("content", "123456"));
        MvcResult mvcResult = resultActions
                .andExpect(MockMvcResultMatchers.status().isOk()) //判断返回状态是否200
                .andReturn();
        String result = mvcResult.getResponse().getContentAsString();
        System.out.println("result:"+result);
    }
    
    //删除
    @Transactional
    @Test
    public void deleteTest() throws Exception {
        mockMvc.perform(MockMvcRequestBuilders.post("/article/delete")
                .param("id", "15"))
                .andExpect(MockMvcResultMatchers.status().isOk());
    }
}
复制代码

  说明事项:

  (1)json-path:该jar包用于解析json,特别方便。

  (2)测试service与测试dao类似:测试dao注入dao的bean;测试service注入service的bean。

  (3)添加@Transactional注解,无论是否执行成功都会回滚事务,好处是不会污染数据库。

  (4)测试Controller中路径不要忘了加斜杠如:/article/add(正确),article/add(错误)。

  (5)测试dao、service与controller相同点都有注解@RunWith与@ContextConfiguration;不同点测试controller要加@WebAppConfiguration。

  (6)注解@ContextConfiguration中的配置文件根据需要设置,例如测试controller要加spring-mvc.xml,测试dao和service则不需要。

  附:源码类

  ArticleDao.java

复制代码
public interface ArticleDao {
    void insert(Article article);
    void delete(Integer id);
    Article getById(Integer id);
    List<Article> getListByParams(Article article);
    List<Article> getAllList();
    void update(Article article);
}
复制代码

  ArticleController.java

复制代码
@Controller
@RequestMapping("/article")
public class ArticleController {
@Autowired private ArticleService articleService; @RequestMapping("/add") @ResponseBody public Result add(Article article) { try { articleService.add(article); return new Result("添加成功!"); } catch (Exception e) { return new Result("500","添加失败"+e); } } @RequestMapping("/delete") @ResponseBody public Result delete(Integer id) { try { articleService.delete(id); return new Result("删除成功!"); } catch (Exception e) { return new Result("500","删除失败!"+e); } } @RequestMapping("/getById") @ResponseBody public Article getById(Integer id) { return articleService.getById(id); } @RequestMapping("/getListByParams") @ResponseBody public List<Article> getListByParams(Article article) { return articleService.getListByParams(article); } @RequestMapping("/getAllList") @ResponseBody public List<Article> getAllList() { return articleService.getAllList(); } @RequestMapping("/update") @ResponseBody public Result update(Article article) { try { articleService.update(article); return new Result("修改成功!"); } catch (Exception e) { return new Result("500","修改失败!"+e); } } @RequestMapping(value = "detail") public String detail(Integer id, Model model) { Article article = articleService.getById(id); model.addAttribute("article", article); return "page/detail"; } }
复制代码
