Question

我正在使用：Mockito，Spring test和Hamcrest。

我有一个像这样的用户控制器类：

@RestController 
public class UserController {

private UserResource userResource;

@RequestMapping(value = "/users", method = RequestMethod.POST)
public Response create(@Valid @RequestParam String json) throws ResourceException {
    System.out.println(json);
    Response response = userResource.insert(json);
    return response;
}

}

这是我的考验。我的方法userResource.insert使用户json重新创建用户的实例并保留它：

@Test
public void testPost() throws Exception{
    JsonObjectBuilder jsonObjectBuilder = Json.createObjectBuilder();
    JsonObject user1 = jsonObjectBuilder.add("pseudo", "pseudo1").add("accessToken","accesstoken").add("picture","picture").build();
    System.out.println(user1.toString());
    User user =  new User();
    user.setId(1);
    user.setPseudo("pseudo1");
    user.setAccessToken("accesstoken");
    user.setPicture("picture");
    RestResponse<User> restResponse = new RestResponse<User>();
    restResponse.setData(user);
    Response response = restResponse.throw200Ok();

    when(userResource.insert(user1.toString())).thenReturn(response);
    mockMvc.perform(post("/users").accept(MediaType.APPLICATION_JSON))
            .andExpect(status().isOk())
            .andExpect(content().contentType("application/json;charset=UTF-8"))
            .andExpect(jsonPath("$..id").value(1))
            .andExpect(jsonPath("$..pseudo").value("pseudo"))
            .andExpect(jsonPath("$..password").value("password"))
            .andExpect(jsonPath("$..picture").value("picture"));


    verify(userResource, times(1)).insert(user1.toString());
}

但是，我的测试失败了，当我运行它时出现此消息错误：

java.lang.AssertionError: Status 
Expected :200
Actual   :400

这意味着我正在尝试一个糟糕的请求，但我已经使用我的REST服务器测试它并且它是成功的我不明白我的错误在哪里。我之前做过GET和DELETE测试没有错误。

Answer 1

我认为错误在“接受”部分，应该有“contentType”：

mockMvc.perform(post("/users").contentType(MediaType.APPLICATION_JSON)).content(some_json_data)...

另据我所知，您不会将任何数据发布到“/ users”端点。
