Mockito может только издеваться над не-частными и нефинальными классами, но основная причина этой ошибки может быть друг ⇐ Android

[Anonymous]

Я хочу написать некоторые тесты пользовательского интерфейса для композиционного экрана.
Я постоянно сталкиваюсь с той же ошибкой снова и снова. ViewModel нельзя высмеивать, хотя я объявил класс ViewModel как открытый. < /P>
Вот тестовый код: < /p>
class ReportScreenKtTest {

@get:Rule
val composeTestRule = createComposeRule()

@get:Rule
val mockitoRule: MockitoRule = MockitoJUnit.rule()

@Mock
private lateinit var viewModel: ReportViewModel

@Before
fun setUp() {
whenever(viewModel.errorFlow).thenReturn(MutableSharedFlow())
}

@Test
fun contentState_whenCheckPerformWorkoutCheckBox_addsUpdateCheckBox() {
// given
whenever(viewModel.uiState).thenReturn(
MutableStateFlow(ReportState.Content(
date = 0,
dailyReport = report,
cardios = cardios,
cheatMeals = cheatMeals,
notes = notes))
)

composeTestRule.setContent {
AppSurface {
ReportScreen(viewModel = viewModel, navigateToWorkout = {}, navigateBack = {}, navigateToBodyMeasurement = {})
}
}

// when
composeTestRule.onNodeWithTag(ReportScreenConstants.WORKOUT_CHECK_BOX).performClick()

// then
verify(viewModel).add(ReportEvent.UpdateCheckBox(false, CheckBoxField.Workout))
}
< /code>
И вот мой класс ViewModel: < /p>
open class ReportViewModel @Inject constructor(
getDailyReport: GetDailyReport,
private val deleteReport: DeleteDailyReport,
private val updateReport: UpdateDailyReport,
private val savedStateHandle: SavedStateHandle,
// othet use cases
): BlocViewModel() {

// events, state, etc
}
< /code>
Я всегда получаю эту ошибку: < /p>
rg.mockito.exceptions.base.MockitoException:
Mockito cannot mock this class: class com.example.fitness_routine.presentation.ui.screen.report.ReportViewModel.

Mockito can only mock non-private & non-final classes, but the root cause of this error might be different.
Please check the full stacktrace to understand what the issue is.
If you're still not sure why you're getting this error, please open an issue on GitHub.

IMPORTANT INFORMATION FOR ANDROID USERS:

The regular Byte Buddy mock makers cannot generate code on an Android VM!
To resolve this, please use the 'mockito-android' dependency for your application:

is there anything wrong in my dependencies ? Any compatibility issues with Kotlin version?
