How to mock Dagger activity object graphs?

Question

I'm using Dagger in an android app to provide application and activity scope graphs. And I'm using Robolectric for unit-testing. I know that I can provide Robolectric with a substitute Application class that is configured with an application object graph that overrides the real one with mocks. But I'm stumped as to how to do the same with the activity object graphs since the standard pattern for activity object graphs is for the activities themselves to instantiate the activity-specific Dagger module they need. Any suggestions would be greatly appreciated.
