How to fake ViewModel in android for unit tests

I need to write the test for Fragment and I need it takes a data from fake repository. I created fake Fragment for test with val fragmentScenario = launchFragmentInContainer and initialized repository with a fake repository but if I just use real view model it is try to take a data from real repository. So I guess I have to use fake ViewModel to take a data from fake repository. But I didnt figured out how to fake it. How can I fake it?

@RunWith(AndroidJUnit4::class)
@ExperimentalCoroutinesApi
class WeatherForecastFragmentTest {
    private lateinit var weatherRepository: WeatherRepository
    private lateinit var locationRepository: LocationRepository
    private lateinit var weatherViewModel: WeatherForecastViewModel

    @Before
    fun initRepository() = runTest {
        locationRepository = FakeAndroidLocationRepository()
        weatherRepository = FakeAndroidWeatherRepository()
        weatherViewModel = WeatherForecastViewModel(weatherRepository, locationRepository)
        cleanDb()
    }

 @Test
    fun initViewModel_loadListWeather_DisplayedInUi() = runBlockingTest {
        val location = Location(1, "Moscow")

        val bundle = WeatherForecastFragmentArgs(location.id, location.name).toBundle()
        val fragmentScenario = launchFragmentInContainer<WeatherForecastFragment>(
            bundle, R.style.ThemeOverlay_AppCompat_Light
        )

        Espresso.onView(ViewMatchers.withId(R.id.weatherForecastRecyclerView))
            .check(matches(isDisplayed()))```
