模拟MVC-添加请求参数进行测试 [英] Mock MVC - Add Request Parameter to test

问题描述

我正在使用Spring 3.2模拟MVC来测试我的控制器.我的代码是

I am using spring 3.2 mock mvc to test my controller.My code is

 @Autowired
     private Client client;

     @RequestMapping(value = "/user", method = RequestMethod.GET)
        public String initUserSearchForm(ModelMap modelMap) {
            User user = new User();
            modelMap.addAttribute("User", user);
            return "user";
        }

        @RequestMapping(value = "/byName", method = RequestMethod.GET)
        @ResponseStatus(HttpStatus.OK)
        public
        @ResponseBody
        String getUserByName(
           @RequestParam("firstName") String firstName,
           @RequestParam("lastName") String lastName,
           @ModelAttribute("userClientObject") UserClient userClient) {
            return client.getUserByName(userClient, firstName, lastName);
        }

我写了以下测试:

@Test public void testGetUserByName() throws Exception {
        String firstName = "Jack";
        String lastName = "s";       
        this.userClientObject = client.createClient();
        mockMvc.perform(get("/byName")
                .sessionAttr("userClientObject", this.userClientObject)
                .param("firstName", firstName)
                .param("lastName", lastName)               
        ).andExpect(status().isOk())
                .andExpect(content().contentType("application/json"))
                .andExpect(jsonPath("$[0].id").exists())
                .andExpect(jsonPath("$[0].fn").value("Marge"));
}

我得到的是

java.lang.AssertionError: Status expected:<200> but was:<400>
    at org.springframework.test.util.AssertionErrors.fail(AssertionErrors.java:60)
    at org.springframework.test.util.AssertionErrors.assertEquals(AssertionErrors.java:89)
    at org.springframework.test.web.servlet.result.StatusResultMatchers$5.match(StatusResultMatchers.java:546)
    at org.springframework.test.web.servlet.MockMvc$1.andExpect(MockMvc.java:141)

为什么会这样?通过@RequestParam

Why this happens? Is it right way to pass the @RequestParam

推荐答案

当我分析您的代码时.我也遇到过同样的问题，但是我的问题是，如果我同时提供名字和姓氏的值，则表示它工作正常.但是当我只给出一个值时，它表示400.无论如何，请使用.andDo(print())方法找出错误

When i analyzed your code. I have also faced the same problem but my problem is if i give value for both first and last name means it is working fine. but when i give only one value means it says 400. anyway use the .andDo(print()) method to find out the error

public void testGetUserByName() throws Exception {
    String firstName = "Jack";
    String lastName = "s";       
    this.userClientObject = client.createClient();
    mockMvc.perform(get("/byName")
            .sessionAttr("userClientObject", this.userClientObject)
            .param("firstName", firstName)
            .param("lastName", lastName)               
    ).andDo(print())
     .andExpect(status().isOk())
            .andExpect(content().contentType("application/json"))
            .andExpect(jsonPath("$[0].id").exists())
            .andExpect(jsonPath("$[0].fn").value("Marge"));
}

如果您的问题是org.springframework.web.bind.missingservletrequestparameterexception，则必须将代码更改为

If your problem is org.springframework.web.bind.missingservletrequestparameterexception you have to change your code to

@RequestMapping(value = "/byName", method = RequestMethod.GET)
    @ResponseStatus(HttpStatus.OK)
    public
    @ResponseBody
    String getUserByName(
        @RequestParam( value="firstName",required = false) String firstName,
        @RequestParam(value="lastName",required = false) String lastName, 
        @ModelAttribute("userClientObject") UserClient userClient)
    {

        return client.getUserByName(userClient, firstName, lastName);
    }
