Question

我正在研究Spring MVC + Mockito并且我开发了以下代码，导致错误不确定是什么问题。

import static org.mockito.Mockito.verifyNoMoreInteractions;
import static org.mockito.Mockito.when;
import static org.springframework.test.web.client.match.MockRestRequestMatchers.content;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

import java.util.Arrays;
import java.util.List;

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.MockitoAnnotations;
import org.springframework.http.MediaType;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;

import com.memorynotfound.config.WebConfig;
import com.memorynotfound.controller.UserController;
import com.memorynotfound.filter.CORSFilter;
import com.memorynotfound.model.User;
import com.memorynotfound.service.UserService;


@WebAppConfiguration
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {WebConfig.class})
public class UserControllerUnitTest {

    private MockMvc mockMvc;

    @Mock
    private UserService userService;

    @InjectMocks
    private UserController userController;

    @Before
    public void init(){
        MockitoAnnotations.initMocks(this);
        mockMvc = MockMvcBuilders.standaloneSetup(userController).addFilters(new CORSFilter()).build();
    }

    @Test
    public void test_get_all_success() throws Exception{
        List<User> users = Arrays.asList(
                new User(1, "Daenerys Targaryen"),
                new User(2, "John Snow"));

        when(userService.getAll()).thenReturn(users);

        mockMvc.perform(get("/users"))
        .andExpect(status().isOk())
        .andExpect(content().contentType(MediaType.APPLICATION_JSON_UTF8_VALUE))
        .andExpect(jsonPath("$", hasSize(2)))
        .andExpect(jsonPath("$[0].id", is(1)))
        .andExpect(jsonPath("$[0].username", is("Daenerys Targaryen")))
        .andExpect(jsonPath("$[1].id", is(2)))
        .andExpect(jsonPath("$[1].username", is("John Snow")));

        verify(userService, times(1)).getAll();
        verifyNoMoreInteractions(userService);
    }
}

我怀疑，与import语句相关的某些内容无效。

@RestController
@RequestMapping("/users")
public class UserController {

    private final Logger LOG = LoggerFactory.getLogger(UserController.class);

    @Autowired
    private UserService userService;

    // =========================================== Get All Users ==========================================

    @RequestMapping(method = RequestMethod.GET)
    public ResponseEntity<List<User>> getAll() {
        LOG.info("getting all users");
        List<User> users = userService.getAll();

        if (users == null || users.isEmpty()){
            LOG.info("no users found");
            return new ResponseEntity<List<User>>(HttpStatus.NO_CONTENT);
        }

        return new ResponseEntity<List<User>>(users, HttpStatus.OK);
    }
}

以下是参考错误：

    The method andExpect(ResultMatcher) in the type ResultActions is not applicable for the arguments (RequestMatcher)

我应该用过这个：

import static org.mockito.Mockito.*;
import static org.hamcrest.Matchers.*;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.*;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;

import java.util.Arrays;
import java.util.List;

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.MockitoAnnotations;

import org.springframework.http.*;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;

import com.memorynotfound.config.WebConfig;
import com.memorynotfound.controller.UserController;
import com.memorynotfound.filter.CORSFilter;
import com.memorynotfound.model.User;
import com.memorynotfound.service.UserService;

ResultActions类型中的方法andExpect（ResultMatcher）不适用于参数（RequestMatcher）
