I have solved this problem using an extra object injected by Dagger, you can find the full example here: https://github.com/fabioCollini/ArchitectureComponentsDemo

In the fragment I am not using directly the ViewModelFactory, I have defined a custom factory defined as a Dagger singleton: https://github.com/fabioCollini/ArchitectureComponentsDemo/blob/master/uisearch/src/main/java/it/codingjam/github/ui/search/SearchFragment.kt

Then in the test I replace using DaggerMock this custom factory using a factory that always returns a mock instead of the real viewModel: https://github.com/fabioCollini/ArchitectureComponentsDemo/blob/master/uisearchTest/src/androidTest/java/it/codingjam/github/ui/repo/SearchFragmentTest.kt
