java - 单元测试验证失败

Question

我正在尝试为代客警报服务测试一个类，但是在验证测试时遇到问题，并且每当尝试验证我的方法时遇到此错误

public void onSpeedAlertActivationJob(ActivateSpeedAlert job) {
        List definitions = job.getActivateSpeedAlertType().getSpeedAlertDefinition();
        if (!JobVerifier.containsValetAlert(definitions)) {
            return;

        }

        if (definitions.size() > 1) {
            Log.w(LOG_TAG, "Received ValetAlert AND other definitions in one job");


            sendSpeedAlertJobAcknowledgement(monitorings.speedalert.ErrorCodes.OTHER_ERROR, job.getId());
            return;
        }

考试：

This is the uni tests for the method
public void onSpeedAlertActivationJobTest() throws Exception{



 /*Execution*/



    ActivateSpeedAlert speedalert=new ActivateSpeedAlert();
    speedalert.setId(80);
    ActivateSpeedAlertType speedalertType=new ActivateSpeedAlertType();
    speedalertType.setSpeedAlertDefinition(new ArrayList();
    speedalert.setActivateSpeedAlertType(speedalertType);
    mValetAlertMock.onSpeedAlertActivationJob(speedalert);

    /*Verification //Error in this part
    verify(mValetAlertMock).sendSpeedAlertJobAcknowledgement(
        monitorings.speedalert.ErrorCodes.OTHER_ERROR, job.getId());
    }

我收到一个 OnSpeedAlertActivationJobTest失败的错误

预期的行为应验证代码

The unit testing for the service is 

    public class ValetAlertTest {

    public static final String LOG_TAG="ValetAlert";
    public final static String CONFIG_LOG_TAG="SpeedAlert";
    public final static OnlineServiceId ONLINE_SERVICE_ID=OnlineServiceId.VALET_ALERT;

    private static final int VALET_ALERT_ID=0;
    private static final String PREF_ENABLED="ValetAlertEnabled";
    private static final String PREF_DEBUG="ValetAlertDebug";
    private static final String PREF_PRIVACY_MODE="ValetAlertPrivacyMode";
    public final static String PREFS_LOCATION_MANAGER="LocationManager";
    public final static String PREF_LOCATION_TRACING="locationTracingAllowed";

    private ValetAlert mValetAlert;

    @AfterClass
    public static void tearDownClass() {
    }

    @Before
    public void setUp() {
        mValetAlert = new ValetAlert();
    }

    @After
    public void tearDown() {
    }

    // TODO add test methods here.
    // The methods must be annotated with annotation @Test. For example:
    //
     @Test
     public void onSpeedAlertActivationJobTest() {
         ActivateSpeedAlert jobTest = new ActivateSpeedAlert();
         jobTest.setId(123);
         ActivateSpeedAlertType actType = new ActivateSpeedAlertType();
         actType.setSpeedAlertDefinition(new ArrayList());

         jobTest.setActivateSpeedAlertType(actType);


         mValetAlert.onSpeedAlertActivationJob(jobTest);

         verify(mValetAlert).sendSpeedAlertJobAcknowledgement(monitorings.speedalert.ErrorCodes.OTHER_ERROR, jobTest.getId());
     }
}

但是单元测试仍然失败并且没有验证代码

Answer 1

在这种情况下，您需要在SUT上输入Spy。否则，Mockito将不会跟踪/验证任何内容：

@Spy
private ValetAlert mValetAlert;

@Before
public void setUp() {
    MockitoAnnotations.initMocks(this);   
}    

仅当不使用 MockitoAnnotations.initMocks(this);时才需要 @RunWith(MockitoJunitRunner.class)。
