嗨，我收到以下错误


org.koin.error.BeanInstanceCreationException: Can't create definition for 'Single [name='NetworkControllerContract',class='com.network.contract.NetworkControllerContract']' due to error :

Mockito cannot mock this class: class com.network.NetworkController.

我已经手动打开了这些课程..

open class NetworkController constructor(private val networkHelper: NetworkHelperContract) : NetworkControllerContract{.....}

open interface NetworkControllerContract {
}

//my test class

@RunWith(AndroidJUnit4::class)
class MyUnitTest: KoinTest {

   single<NetworkControllerContract> {
            Mockito.mock(NetworkController::class.java) //where it crashes
        }

   val networkController: NetworkControllerContract by inject()

}

我使用的依赖项


   def mockito = "2.21.0"

//android instrumental test
    androidTestImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1'
    androidTestImplementation 'androidx.test.ext:junit:1.1.0'

    androidTestImplementation('androidx.arch.core:core-testing:2.0.0') {

    }

问题出在您的设置中：

testImplementation "org.mockito:mockito-android:$mockito"

此依赖项使用 Android 内部，在运行单元测试时不可用。

嘲讽是我的决定

@RunWith(AndroidJUnit4::class)
class DashboardFragmentTest : KoinTest {
@Rule
@JvmField
val activityRule = ActivityTestRule(SingleFragmentActivity::class.java, true, true)
@Rule
@JvmField
val executorRule = TaskExecutorWithIdlingResourceRule()
@Rule
@JvmField
val countingAppExecutors = CountingAppExecutorsRule()

private val testFragment = DashboardFragment()

private lateinit var dashboardViewModel: DashboardViewModel
private lateinit var router: Router

private val devicesSuccess = MutableLiveData<List<Device>>()
private val devicesFailure = MutableLiveData<String>()

@Before
fun setUp() {
    dashboardViewModel = Mockito.mock(DashboardViewModel::class.java)
    Mockito.`when`(dashboardViewModel.devicesSuccess).thenReturn(devicesSuccess)
    Mockito.`when`(dashboardViewModel.devicesFailure).thenReturn(devicesFailure)
    Mockito.`when`(dashboardViewModel.getDevices()).thenAnswer { _ -> Any() }

    router = Mockito.mock(Router::class.java)
    Mockito.`when`(router.loginActivity(activityRule.activity)).thenAnswer { _ -> Any() }

    StandAloneContext.loadKoinModules(hsApp + hsViewModel + api + listOf(module {
        single(override = true) { router }
        factory(override = true) { dashboardViewModel } bind ViewModel::class
    }))

    activityRule.activity.setFragment(testFragment)
    EspressoTestUtil.disableProgressBarAnimations(activityRule)
}

@After
fun tearDown() {
    activityRule.finishActivity()
    StandAloneContext.closeKoin()
}

@Test
fun devicesCall() {
    onView(withId(R.id.rv_devices)).check(ViewAssertions.matches(ViewMatchers.isCompletelyDisplayed()))
    Mockito.verify(dashboardViewModel, Mockito.times(1)).getDevices()
}

}
