Question

当使用@MockMvcTest测试控制器时，我们如何使用属性 - 示例.andExpect（model（）。attributeExists（“classActiveLogin”））

我有这样的测试

@AutoConfigureMockMvc(secure = false)
@RunWith(SpringRunner.class)
@WebMvcTest({HomeController.class, ShoppingCartController.class})
public class ShoppingCartControllerTest {

    @MockBean
    private UserDetailsServiceImpl userDetailsService;

    @Autowired
    private MockMvc mockMvc;

    @MockBean
    private SecurityUtility securityUtility;

    @MockBean
    private BookService bookService;

    @MockBean
    private UserService userService;

    @MockBean
    private CartItemService cartItemService;

    @Test
    public void showLoginPage() throws Exception {

        mockMvc.perform(get("/login")
                .accept(MediaType.TEXT_HTML)
                .contentType(MediaType.TEXT_HTML)
        )
                .andExpect(model().attributeExists("classActiveLogin"))
                .andReturn();
    }

我得到了一个堆栈跟踪

MockHttpServletRequest:
      HTTP Method = GET
      Request URI = /login
       Parameters = {}
          Headers = {Content-Type=[text/html], Accept=[text/html]}

Handler:
             Type = org.springframework.web.servlet.resource.ResourceHttpRequestHandler

Async:
    Async started = false
     Async result = null

Resolved Exception:
             Type = null

ModelAndView:
        View name = null
             View = null
            Model = null

FlashMap:
       Attributes = null

MockHttpServletResponse:
           Status = 404
    Error message = null
          Headers = {}
     Content type = null
             Body = 
    Forwarded URL = null
   Redirected URL = null
          Cookies = []

java.lang.AssertionError: No ModelAndView found

这是我的方法

@RequestMapping("/login")
public String login(Model model) {
    model.addAttribute("classActiveLogin", true);
    return "Myaccount";
}

那么测试究竟出了什么问题呢？谢谢我怀疑@WebMvcTest不会添加特定的上下文可能是域模型，有什么方法可以解决它？

我的控制器

 @RequestMapping("/login")
    public String login(Model model) {
        model.addAttribute("classActiveLogin", true);
        return "Myaccount";
    }

您的状态404未找到，这意味着您的请求与控制器类中的任何请求映射都不匹配。

MockHttpServletResponse:
           Status = 404

您的控制器类是如何注释的？

向Controller测试添加属性
