Nitrogen in your (test) pyramid.
summary
Project Nitrogen promises a single entry point so tests written once can target emulator, device lab and CI, but the implementation is partial: Robolectric 4.0 and androidx.test 1.0.0 converge on common APIs while Robolectric adds support for AndroidJUnit4, ActivityTestRule and Espresso. The practical stack includes network mocking, deterministic fake servers, robot patterns and state verifiers, and cloud device farms; gaps and environment inconsistencies remain so write once run everywhere is an aspiration not yet solved.
