Question

在Junit测试中是否可以发出发布请求并使用BDDMockito.given（）设置响应RestController帖子的方法所使用的Service的返回？如果可能，该怎么办？

我正在尝试设置Service的返回值，并且在RestController方法中，Service返回null并且测试失败。

这些是代码：

测试：

@RunWith(SpringRunner.class)
@SpringBootTest(classes = {SecurityBeanOverrideConfiguration.class, AccountApp.class})
public class UserSystemResourceIntTest {

    @MockBean
    private UserSystemService userSystemServiceMock;

    private MockMvc restUserSystemMockMvc;

    private UserSystem userSystem;

    public static UserSystem createEntity(EntityManager em) {
        UserSystem userSystem = new UserSystem()
            .name(DEFAULT_NAME)
            .email(DEFAULT_EMAIL)
            .phone(DEFAULT_PHONE)
            .documentCode(DEFAULT_DOCUMENT_CODE)
            .documentType(DEFAULT_DOCUMENT_TYPE)
            .gender(DEFAULT_GENDER)
            .createdOn(null)
            .updateOn(null)
            .active(null)
            .userId(null);

        return userSystem;
    }

    @Before
    public void initTest() {
        userSystem = createEntity(em);
    }

    @Test
    @Transactional
    public void createUserSystem() throws Exception {
        int databaseSizeBeforeCreate = userSystemRepository.findAll().size();

        // Create the UserSystem
        UserSystemDTO userSystemDTO = userSystemMapper.toDto(userSystem);

        userSystemDTO.setLangKey(DEFAULT_LANG_KEY);

        given(userSystemServiceMock.newAccount(userSystemDTO)).willReturn(createNewUserSystemDTO());


        restUserSystemMockMvc.perform(post("/api/user-systems")
            .contentType(TestUtil.APPLICATION_JSON_UTF8)
            .content(TestUtil.convertObjectToJsonBytes(userSystemDTO)))
            .andExpect(status().isCreated()); // FAIL BECAUSE RETURN STATUS 500

        // Validate the UserSystem in the database
        List<UserSystem> userSystemList = userSystemRepository.findAll();
        assertThat(userSystemList).hasSize(databaseSizeBeforeCreate + 1);
        UserSystem testUserSystem = userSystemList.get(userSystemList.size() - 1);
        assertThat(testUserSystem.getName()).isEqualTo(DEFAULT_NAME);
        assertThat(testUserSystem.getEmail()).isEqualTo(DEFAULT_EMAIL);
        assertThat(testUserSystem.getPhone()).isEqualTo(DEFAULT_PHONE);
        assertThat(testUserSystem.getDocumentCode()).isEqualTo(DEFAULT_DOCUMENT_CODE);
        assertThat(testUserSystem.getDocumentType()).isEqualTo(DEFAULT_DOCUMENT_TYPE);
        assertThat(testUserSystem.getGender()).isEqualTo(DEFAULT_GENDER);
        assertThat(testUserSystem.getCreatedOn()).isNotNull(); //isEqualTo(DEFAULT_CREATED_ON);
        assertThat(testUserSystem.getUpdateOn()).isNull(); // EqualTo(DEFAULT_UPDATE_ON);
        assertThat(testUserSystem.isActive()).isEqualTo(DEFAULT_ACTIVE);
        assertThat(testUserSystem.getUserId()).isEqualTo(DEFAULT_USER_ID);

        // Validate the UserSystem in Elasticsearch
        verify(mockUserSystemSearchRepository, times(1)).save(testUserSystem);
    }

    private static UserSystemDTO createNewUserSystemDTO() {
        UserSystemDTO newUserSystemDTO = new UserSystemDTO(
                DEFAULT_USER_ID, DEFAULT_NAME, DEFAULT_EMAIL, 
                DEFAULT_PASSWORD, DEFAULT_PHONE, DEFAULT_PHONE, 
                DEFAULT_DOCUMENT_TYPE, DEFAULT_GENDER, DEFAULT_LANG_KEY, 
                null, null, null, null);

        return newUserSystemDTO;

    }

}

RestController：

@RestController
@RequestMapping("/api")
public class UserSystemResource {

    private final UserSystemService userSystemService;

    private final UserSystemQueryService userSystemQueryService;

    public UserSystemResource(UserSystemService userSystemService, UserSystemQueryService userSystemQueryService) {
        this.userSystemService = userSystemService;
        this.userSystemQueryService = userSystemQueryService;
    }

    @PostMapping("/user-systems")
    public ResponseEntity<UserSystemDTO> createUserSystem(@Valid @RequestBody UserSystemDTO userSystemDTO) throws URISyntaxException {
        log.debug("REST request to save UserSystem : {}", userSystemDTO);
        if (userSystemDTO.getId() != null) {
            throw new BadRequestAlertException("A new userSystem cannot already have an ID", ENTITY_NAME, "idexists");
        }
        UserSystemDTO result = userSystemService.newAccount(userSystemDTO);
        return ResponseEntity.created(new URI("/api/user-systems/" + result.getId()))
            .headers(HeaderUtil.createEntityCreationAlert(ENTITY_NAME, result.getId().toString()))
            .body(result);
    }

}

控制台错误：

java.lang.NullPointerException: null
    at com.fournetwork.account.web.rest.UserSystemResource.createUserSystem(UserSystemResource.java:60)
    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
    at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)
    at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)

结果测试错误：

createUserSystem(com.fournetwork.account.web.rest.UserSystemResourceIntTest)  Time elapsed: 205.661 s  <<< FAILURE!
    ava.lang.AssertionError: Status expected:<201> but was:<500>

在Junit上使用MockMvc进行模拟返回失败
