Question

我正在使用mockito和junit并对spring mvc进行单元测试我的代码流是：

Service Layer - ＆gt; Model Layer - ＆gt; Controller Layer

我成功使用代码

对模型层测试Controller

@RunWith(MockitoJUnitRunner.class)
public class HashLinkerControllerTest {

private static final Logger LOGGER = Logger
        .getLogger(HashLinkerControllerTest.class);



@Mock
private HashLinkerModel modelMock;

@InjectMocks
private HashLinkerController controller;

private MockMvc mockMvc;

@Before
public void setup() {

    MockitoAnnotations.initMocks(this);
    this.mockMvc = MockMvcBuilders.standaloneSetup(controller).build();

}

  @Test
public void update() throws Exception {
    int date = 123;
    String hashToCheck = "asdfasdfasdfasdfas";
    HashLinker first = this.createHashLinker(hashToCheck, "some name",
            "some des", "some data", date);

    when(modelMock.update(first)).then(returnsFirstArg());
    mockMvc.perform(
            put("/api/hashService/" + hashToCheck)
                    .contentType(TestUtil.APPLICATION_JSON_UTF8)
                    .content(
                            TestUtil.convertObjectToJsonBytesWithSettersOnly(first))
                    .accept(TestUtil.APPLICATION_JSON_UTF8))
            .andExpect(status().isOk())
            .andExpect(
                    content().contentType(TestUtil.APPLICATION_JSON_UTF8))
            .andExpect(jsonPath("$.hash", is(hashToCheck)))
            .andExpect(jsonPath("$.description", is("some des")))
            .andExpect(jsonPath("$.name", is("some name")));

    verify(modelMock, times(1)).update(first);
    verifyNoMoreInteractions(modelMock);
}

但现在我正在寻找一种测试3层结构的方法。即测试控制器的服务。我提出了：

@RunWith(MockitoJUnitRunner.class)
public class HashLinkerControllerServiceLayerTest {

private static final Logger LOGGER = Logger
        .getLogger(HashLinkerControllerServiceLayerTest.class);

@Mock
private HashLinkerService serviceMock;

@InjectMocks
// @Mock
private HashLinkerModel modelMock;

private HashLinkerController controller;

private MockMvc mockMvc;

@Before
public void setup() {

    MockitoAnnotations.initMocks(this);
    controller = new HashLinkerController(modelMock);
    this.mockMvc = MockMvcBuilders.standaloneSetup(controller).build();

}

并使用

进行测试

@Test
public void update() throws Exception {
    int date = 123;
    String hashToCheck = "asdfasdfasdfasdfas";
    HashLinker first = this.createHashLinker(hashToCheck, "some name",
            "some des", "some data", date);

    when(serviceMock.update(first)).then(returnsFirstArg());
    mockMvc.perform(
            put("/api/hashService/" + hashToCheck)
                    .contentType(TestUtil.APPLICATION_JSON_UTF8)
                    .content(
                            TestUtil.convertObjectToJsonBytesWithSettersOnly(first))
                    .accept(TestUtil.APPLICATION_JSON_UTF8))
            .andExpect(status().isOk())
            .andExpect(
                    content().contentType(TestUtil.APPLICATION_JSON_UTF8))
            .andExpect(jsonPath("$.hash", is(hashToCheck)))
            .andExpect(jsonPath("$.description", is("some des")))
            .andExpect(jsonPath("$.name", is("some name")));

    verify(serviceMock, times(1)).update(first);
    verifyNoMoreInteractions(serviceMock);
}

测试与上述相同，我将modelMock更改为serviceMock。由于某种原因，此测试失败。我得到404。任何想法？

修改：

@Component
public class HashLinkerModel {

private static final Logger LOGGER = Logger.getLogger(HashLinkerModel.class);

HashLinkerService service;

/** The unicode service. */
UnicodeService unicodeService;

@Autowired
public HashLinkerModel(HashLinkerService service, UnicodeService unicodeService){
    this.service = service;
    this.unicodeService = unicodeService;

}




     /**
 * check if hash exists before creation
 * @param toHash
 * @return
 */
private HashLinker checkAndcreate(HashLinker toHash){


    String hash = this.createHash(toHash.getData());
    toHash.setHash(hash);

    LOGGER.info("add " + hash + ". this is the hash of string " + toHash.getData());

    /* if this hash already in system. return null. otherwise create */
    HashLinker exists =  service.findByHash(toHash.getHash());

    if (null != exists) 
        return exists;
//** we use service here ** 
    return service.create(toHash);
}

public HashLinker create(HashLinker entity) {
    // TODO Auto-generated method stub

    RestPreconditions.checkRequestElementNotNull(entity, LOGGER);
    RestPreconditions.checkRequestElementNotNull(entity.getData(), LOGGER);

    String uniName = getUniHelper().unicode(entity.getName());
    String uniDesc = getUniHelper().unicode(entity.getDescription());

    HashLinker toHash = new HashLinker();
    toHash.setData(entity.getData());

    toHash.setType(entity.getType());

    String baseURL = entity.getBaseURL();

    if (null != baseURL) 
            baseURL  = (baseURL.length() > HashLinker.getIntMaxBaseURL()) ? baseURL.substring(0, HashLinker.getIntMaxBaseURL()) : baseURL;

    toHash.setBaseURL(baseURL);
    toHash.setStatus(0);
    // update lecker's macros results
    toHash.setName(uniName);
    toHash.setDescription(uniDesc);


    return checkAndcreate(toHash);

}

点击你的行

verify(serviceMock, times(1)).update(first);

后

mockMvc.perform(
        put("/api/hashService/" + hashToCheck)
                .contentType(TestUtil.APPLICATION_JSON_UTF8)
                .content(
                        TestUtil.convertObjectToJsonBytesWithSettersOnly(first))
                .accept(TestUtil.APPLICATION_JSON_UTF8));

但在mockMvc断言之前，要验证是否使用了mock。

您的代码的一般问题：

使用注释@RunWith(MockitoJUnitRunner.class)手动初始化Mockito是不必要的。

<强> @MockitoJUnitRunner

初始化使用Mock注释的模拟，因此不需要明确使用 MockitoAnnotations.initMocks（Object）。
单元测试

我正在寻找一种测试3层结构的方法。

当测试涉及三个层时，测试是集成测试。
在单元测试中，最好有许多小方法来测试不同的行为。因此，一种方法应该测试HTTP响应，其次应该验证服务是否被调用。
