在单元测试中不执行函数。

Question

我觉得这很难解释，但我会尽量保持简单--我正在编写一个单元测试，其中函数(getQualityControlCheckDataForUplift())在另一个类中被访问，但是它确实进入了函数并执行了它应该做的事情，它直接得到了返回语句。

这就是功能。我是不是应该嘲笑QualityControlCheck，它是一个data class

我缩短了代码，使其变得清晰和易于理解。

在我的测试案例中，

qualityControlChecksDataProvider.loadMapWithQCChecksForMilestone()

• I加载MAP -
• ，然后在测试用例中调用orderStateMonitor.upliftedVolumeUpdated()时，orderStateMonitor访问该映射。哪个实习生通过showQualityControlChecks()
• cannot访问getQualityControlCheckDataForUplift()进入getQualityControlCheckDataForUplift()不知道为什么

如果代码不容易理解的话，任何建议都会很有帮助，我真的很抱歉。

   fun getQualityControlCheckDataForUplift(qualityControlMilestone: QualityControlMilestone, uplift: Float):
        ArrayList<QualityControlCheck>? {
        val qcChecksForUplift: ArrayList<QualityControlCheck>? = ArrayList()
        val qcChecksForMilestone = mapOfQCChecksForMilestone[qualityControlMilestone.milestoneText]
        qcChecksForMilestone?.forEach {
            if (it.uplift == uplift) qcChecksForUplift?.add(it)
        }
        return qcChecksForUplift
    } 

我的测试用例

@RunWith(MockitoJUnitRunner::class)
class OrderStateMonitorTest : BaseTest() {

 @InjectMocks
    private lateinit var orderStateMonitor: OrderStateMonitor
@Mock
    private lateinit var qualityControlCheckRequiredDuringFuellingBus: QualityControlCheckRequiredDuringFuellingBus
@Mock
    private lateinit var qualityControlChecksDataProvider: QualityControlChecksDataProvider


  @Before
    fun setUp() {
        qualityControlChecksDataProvider = QualityControlChecksDataProvider(offlineDataStorage, app)
    }
  @Test
    fun `upliftedVolumeUpdated abcdefg`() {

        qualityControlChecksDataProvider.loadMapWithQCChecksForMilestone()
        every(fuelOrderValuesProvider.upliftedVolume()).thenReturn(1000.0f)

        orderStateMonitor.upliftedVolumeUpdated()

        verify(qualityControlCheckRequiredDuringFuellingBus, never()).postUnavailable()
        verify(qualityControlCheckRequiredDuringFuellingBus, once()).postAvailable(qualityControlChecks)
    }
}

OrderStateMonitor

class OrderStateMonitor @Inject constructor(
    private val orderStorage: CurrentOrderStorage,
    private val fuelOrderValuesProvider: FuelOrderValuesProvider,
    private val noServiceRequiredAvailabilityBus: NoServiceRequiredAvailabilityBus,
    private val qualityControlCheckRequiredDuringFuellingBus: QualityControlCheckRequiredDuringFuellingBus,
    private val qualityControlChecksDataProvider: QualityControlChecksDataProvider
) {
     fun upliftedVolumeUpdated() {
        showQualityControlChecks()
    }

       private fun showQualityControlChecks() {
           // WHEN I TRY TO ACCESS ` //qualityControlChecksDataProvider.getQualityControlCheckDataForUplift` IT DOES NOT GET INTO THAT FUNCTION
              val qualityControlChecks =
                qualityControlChecksDataProvider.getQualityControlCheckDataForUplift(
                    QualityControlMilestone.FUELLING, 1000.0f)
    }
}

QualityControlChecksDataProvider

class QualityControlChecksDataProvider @Inject constructor(
    private val offlineDataStorage: OfflineDataStorage,
    private val app: App
) {
    private val mapOfQCChecksForMilestone = LinkedHashMap<String, ArrayList<QualityControlCheck>?>()

    fun loadMapWithQCChecksForMilestone() {
        QualityControlMilestone.values().forEach {
            mapOfQCChecksForMilestone.put(it.milestoneText, getQualityControlCheckDataForMilestone(it))
        }
    }

    fun getQualityControlCheckData(qualityControlMilestone: QualityControlMilestone):
        ArrayList<QualityControlCheck>? =
        mapOfQCChecksForMilestone[qualityControlMilestone.milestoneText]

    fun getQualityControlCheckDataForUplift(qualityControlMilestone: QualityControlMilestone, uplift: Float):
        ArrayList<QualityControlCheck>? {
       //DOES NOT GET INTO THIS FUNCTION  I RUN THE TEST CASE
        val qcChecksForUplift: ArrayList<QualityControlCheck>? = ArrayList()
        val qcChecksForMilestone = mapOfQCChecksForMilestone[qualityControlMilestone.milestoneText]
        qcChecksForMilestone?.forEach {
            if (it.uplift == uplift) qcChecksForUplift?.add(it)
        }
        return qcChecksForUplift
    }
  //THERE ARE OTHER PRIVATE FUNCTION WHICH THE ABOVE CODE WILL ACCESS WHICH WORK FINE
}

Answer 1

方法没有执行，因为您模拟了类。

@RunWith(MockitoJUnitRunner::class)
class OrderStateMonitorTest : BaseTest() {

 @InjectMocks
    private lateinit var orderStateMonitor: OrderStateMonitor
@Mock
    private lateinit var qualityControlCheckRequiredDuringFuellingBus: QualityControlCheckRequiredDuringFuellingBus

    private lateinit var qualityControlChecksDataProvider: QualityControlChecksDataProvider


  @Before
    fun setUp() {
        qualityControlChecksDataProvider = spy(QualityControlChecksDataProvider(offlineDataStorage, app))
    }
  @Test
    fun `upliftedVolumeUpdated abcdefg`() {

        qualityControlChecksDataProvider.loadMapWithQCChecksForMilestone()
        every(fuelOrderValuesProvider.upliftedVolume()).thenReturn(1000.0f)

        orderStateMonitor.upliftedVolumeUpdated()

        verify(qualityControlCheckRequiredDuringFuellingBus, never()).postUnavailable()
        verify(qualityControlCheckRequiredDuringFuellingBus, once()).postAvailable(qualityControlChecks)
    }
}

或者使用CALL_REAL_METHOD

@RunWith(MockitoJUnitRunner::class)
class OrderStateMonitorTest : BaseTest() {

 @InjectMocks
    private lateinit var orderStateMonitor: OrderStateMonitor
@Mock
    private lateinit var qualityControlCheckRequiredDuringFuellingBus: QualityControlCheckRequiredDuringFuellingBus

    private lateinit var qualityControlChecksDataProvider: QualityControlChecksDataProvider

// java syntax
@before
public void setUp(){
  qualityControlChecksDataProvider = mock(QualityControlChecksDataProvider, Mocktio.CALL_REAL_METHOD);
}

  @Test
    fun `upliftedVolumeUpdated abcdefg`() {
        qualityControlChecksDataProvider.loadMapWithQCChecksForMilestone()
        every(fuelOrderValuesProvider.upliftedVolume()).thenReturn(1000.0f)

        orderStateMonitor.upliftedVolumeUpdated()

        verify(qualityControlCheckRequiredDuringFuellingBus, never()).postUnavailable()
        verify(qualityControlCheckRequiredDuringFuellingBus, once()).postAvailable(qualityControlChecks)
    }
}
