Android podpira več vrst testiranja — unit teste (logika, se izvajajo na JVM-u), instrumentirane teste (se izvajajo na napravi/emulatorju, vključno s testi uporabniškega vmesnika s pomočjo Espresso) in še več. Dobra testna strategija izboljša zanesljivost in zaupanje.
Vrste testov
UNIT TESTS (local, on the JVM) → test logic (ViewModels, repositories, utilities):
→ fast (no device); use JUnit, Mockito/MockK (mocking), no Android framework needed
→ for business logic, data processing, ViewModels
INSTRUMENTED TESTS (on a device/emulator) → test code needing the Android framework:
→ UI tests (ESPRESSO — interact with and verify the UI), integration tests
→ slower (real device/emulator) but test real Android behavior
