Highly testable app architecture with Mobius
summary
Claims that Mobius plus Kotlin coroutines yields a highly testable app architecture, implemented as Mobius + Kotlin + coroutines with Mobius fragments, effect handlers, view states and presenters. Concrete deliverable: a working login feature wired to an effect handler that hits a backend and emits events; tests include pure unit tests of the update function, Espresso instrumentation, g-unit, Mockito and a custom Espresso extension. Result: tests exercise UI and effects and approach targets near 100% feature coverage with pure update function tests for deterministic logic.
