java - 如何为 Postmapping 方法编写 junit 测试

Question

我有一个显示带有名称的字段的程序，用户需要输入它们。我该如何测试这个？

User.java - 用户类。

public class User {
    @NotEmpty
    private String firstName;

    @NotEmpty
    private String lastName;

public String getAllInfo() {
        return this.firstName + '\n' + this.lastName;
    }

//getters and setters

}

Store.java - 我的 Controller 类。

public class Store {

...

@PostMapping("/cart/index")
    public String getInfo(@Valid final User user, final Model model) {
        Store.LOGGER.info("{}", user.getAllInfo());
        return "cart/index";
    }

@GetMapping(value = "cart/index")
    public String index(final Model model) {
        model.addAttribute("user", new User());
        return "cart/index";
    }

...
}

我的 junit 测试现在失败，并且收到以下消息。

null
null
MockHttpServletRequest:
      HTTP Method = POST
      Request URI = /cart/index
       Parameters = {}
          Headers = {Accept=[application/json]}

Handler:
             Type = app.vlad.store.Store
           Method = public java.lang.String app.vlad.store.Store.getInfo(app.vlad.user.User,org.springframework.ui.Model)

Async:
    Async started = false
     Async result = null

Resolved Exception:
             Type = null

ModelAndView:
        View name = cart/index
             View = null
        Attribute = user
            value = app.vlad.user.User@248deced
           errors = []

FlashMap:
       Attributes = null

MockHttpServletResponse:
           Status = 200
    Error message = null
          Headers = {}
     Content type = null
             Body = 
    Forwarded URL = cart/index
   Redirected URL = null
          Cookies = []

java.lang.AssertionError:JSON 路径“$.firstName”没有值，异常:json 不能为 null 或为空

我的测试:

StoreTest.java

public class StoreTest {

    @Autowired
    MockMvc        mockMvc;

    @Mock
    private User   user;
    @Mock
    private Model  model;
    @Mock
    Store          store;

    @Autowired
    List<Products> products;

    @Before
    public void setup() {

        MockitoAnnotations.initMocks(this);
        final Store store = new Store(this.products);

        this.mockMvc = MockMvcBuilders.standaloneSetup(store).build();

    }
@Test
    public void testGetInfo() throws Exception {
        this.user.setFirstName("Ivan");
        this.user.setLastName("Ivanov");

        this.mockMvc
                .perform(MockMvcRequestBuilders.post("/cart/index")
                        .accept(MediaType.APPLICATION_JSON))
                .andDo(MockMvcResultHandlers.print())
                .andExpect(MockMvcResultMatchers.status().isOk())
                .andExpect(MockMvcResultMatchers.jsonPath("$.firstName").value("Ivan"))
                .andExpect(MockMvcResultMatchers.jsonPath("$.lastName").value("Ivanov"));

    }
}

最好的方法是使用 SpringBootTest。这将启动一个 Spring Boot 应用程序，然后您可以使用 RestAssured 之类的东西来调用 API。
