调用服务类方法时，Mockito 存根不起作用

Question

我试图存根假设由特定服务方法返回到控制器中存在的方法的一组数据，因此我需要存根三个方法调用（getLopaReConfigPath、getBASeatKit 和 getBAColumnSeatKit），它仅适用于一个方法并且不适用于其他方法！！！

下面是要测试的Controller方法的代码

@RequestMapping(value = "/getSeatLayoutDisplay", method = RequestMethod.POST)
    @ResponseBody JSONObject getSeatLayoutDisplay(@RequestBody String params) {

        JSONObject resultJson = new JSONObject();
        JSONObject  combinedJson = new JSONObject();

        try {
            JsonObject gsonData = parseRequestDataToJson(params);

            StringBuffer filePathBuf = new StringBuffer(commonUtil.getLopaReConfigPath(gsonData.get("carrierName").getAsString(), gsonData.get("dbName").getAsString()));
            filePathBuf.append(LoadPropertyFiles.getInstance().getProperty("INPUT"));

            String seatKitXmlFilePath = filePathBuf.append(LoadPropertyFiles.getInstance().getProperty("XMLS")).toString();
            String columnXMl = filePathBuf.append(Constants.COLUMN_XML_FILENAME).toString();

            BASeatKitInfo seatKitInfo = lopaReConfigService.getBASeatKit(seatKitXmlFilePath);
            KitLayout columnSeatKitLeft = lopaReConfigService.getBAColumnSeatKit(gsonData.get("filepath").getAsString(),columnXMl);

            combinedJson.put("kitLayoutCenter", columnSeatKitLeft);
            combinedJson.put("kitInfo", seatKitInfo);

            resultJson.put("lopaReconfig",combinedJson);

        } catch (Exception e) {
            logger.error(" Failed due to " + e);

        }
        return resultJson;

    }

以下是我返回的测试用例

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(loader=AnnotationConfigWebContextLoader.class)
@WebAppConfiguration
public class LopaReConfigControllerTest {


    public static final MediaType APPLICATION_JSON_UTF8 = new MediaType(MediaType.APPLICATION_JSON.getType(), MediaType.APPLICATION_JSON.getSubtype(), Charset.forName("utf8"));

    // Application dependency 

    private MockMvc mvc;

    @Mock
    LopaReConfigService lopaReConfigService;

    @Mock
    CommonUtil commonUtil;

    @Mock
    ProcessLopaReconfigFile processLopaReconfigFile;

    @Mock
    DBImportRepository dbImportRepository;

    @InjectMocks
    MockHttpSession session;

    @Autowired
    WebApplicationContext context;

    @InjectMocks
    LopaReConfigController lopaReConfigController;

    @Mock
    UserSessionPool sessionPool;

    @Before
    public void setup() {

        // Process mock annotations
        MockitoAnnotations.initMocks(this);

        this.mvc = MockMvcBuilders.standaloneSetup(lopaReConfigController).build();
    }

    @Test
    public void test_getSeatLayoutDisplay() throws Exception {

    // Construct JSON data to pass as parameter

        BASeatkitDataFeeder seatKitDataFeeder = new BASeatkitDataFeeder();
        Gson gson = new Gson();
        CommonUtil util = new CommonUtil();
        StringBuffer filePathBuff = new StringBuffer();

        filePathBuff.append(util.getLopaReConfigPath("ABC-300ER", "ABC-300ER-B777-v300B"));
        filePathBuff.append(LoadPropertyFiles.getInstance().getProperty("INPUT"));

    seatKitDataFeeder.setBuildVersion("Base");
    seatKitDataFeeder.setCarrierName("ABC-300ER");
    seatKitDataFeeder.setDbId("1558");
    seatKitDataFeeder.setDbName("ABC-300ER-B777-v300B");
    seatKitDataFeeder.setSessionId(session.getId());
    seatKitDataFeeder.setFilepath(filePathBuff.toString());

    String seatKitXmlFilePath = filePathBuff.append(LoadPropertyFiles.getInstance().getProperty("XMLS")).toString();
    String columnXMl = filePathBuff.append(Constants.COLUMN_XML_FILENAME).toString();   

    LopaReConfigRepositoryImpl lopaImpl = new LopaReConfigRepositoryImpl();

    BASeatKitInfo BAinfo = lopaImpl.getBASeatKit(seatKitXmlFilePath);
    KitLayout kitLayout = lopaImpl.getBAColumnSeatKit(seatKitXmlFilePath+Constants.SEATKIT_COLUMN_XML_FILENAME,columnXMl);

    //Stub the result whaen methods get called

        Mockito.when(commonUtil.getLopaReConfigPath("ABC-300ER", "ABC-300ER-B777-v300B")).thenReturn(filePathBuff.toString()); // working fine
        Mockito.when(lopaReConfigService.getBASeatKit(seatKitXmlFilePath)).thenReturn(BAinfo); // not stubbing the BAinfo object when method is called
        Mockito.when(lopaReConfigService.getBAColumnSeatKit("","")).thenReturn(kitLayout); // not stubbing the kitLayout object when method is called

        // Test method logic 

    mvc.perform(post("/getSeatLayoutDisplay")
        .contentType(MediaType.APPLICATION_JSON).content(jsonStub))
        .andExpect(status().isOk()) // After hitting specific URL/URI check the status code fall under 200 series
        .andExpect(content().contentType(APPLICATION_JSON_UTF8)); // Check the return statement is JSON

    // Verify that the the lopaReConfigService is called only once during execution.

    verify(lopaReConfigService, times(0)).getBASeatKit(seatKitXmlFilePath);
    verify(lopaReConfigService, times(0)).getBAColumnSeatKit(seatKitDataFeeder.getFilepath(),columnXMl);
    }
}

问题是我试图为 3 种方法存根对象，但 mockito 在第一个方法被调用时正确设置了结果，但其他两种方法没有发生同样的事情

我尝试过使用 Matcher 并覆盖 equals 和 hashcode 方法，但它仍然没有帮助我。

任何帮助将不胜感激。

使用以下方法可以正常工作

 Mockito.when(commonUtil.getLopaReConfigPath("ABC-300ER", "ABC-300ER-B777-v300B")).thenReturn(filePathBuff.toString()); // working fine

不适用于以下方法

Mockito.when(lopaReConfigService.getBASeatKit(seatKitXmlFilePath)).thenReturn(BAinfo); // not stubbing the BAinfo object when method is called
        Mockito.when(lopaReConfigService.getBAColumnSeatKit("","")).thenReturn(kitLayout); // not stubbing the kitLayout object when method is called

Answer 1

当代码和测试代码中的参数相同时，您没有提供相同的参数。

测试中的KitXmlFilePath 与测试代码中的不同

在你做的测试中

StringBuffer filePathBuff = new StringBuffer();
filePathBuff.append(LoadPropertyFiles.getInstance().getProperty("XMLS")).toString();
String seatKitXmlFilePath = filePathBuff.append(LoadPropertyFiles.getInstance().getProperty("XMLS")).toString();

在测试代码中

StringBuffer filePathBuf = new StringBuffer(commonUtil.getLopaReConfigPath(gsonData.get("carrierName").getAsString(), gsonData.get("dbName").getAsString()));
filePathBuf.append(LoadPropertyFiles.getInstance().getProperty("XMLS")).toString();
String seatKitXmlFilePath = filePathBuf.append(LoadPropertyFiles.getInstance().getProperty("XMLS")).toString();

如果您需要它来匹配任何内容，只需使用 anyString()

这样它将匹配任何字符串

所以你的测试代码可以有

Mockito.when(lopaReConfigService.getBASeatKit(anyString())).thenReturn(BAinfo); // not stubbing the BAinfo object when method is called
        Mockito.when(lopaReConfigService.getBAColumnSeatKit(anyString(),anyString())).thenReturn(kitLayout);

在这种情况下它应该匹配
