Unit testing on Android
summary
Defines unit test as isolating a single method, class or component and shows concrete examples wired in Gradle using Gradle + JUnit + Mockito + Robolectric to run tests on the JVM so Android code runs without a device, demonstrates @Mock, @InjectMocks and Spy behaviors with actual assertions, and runs coverage with JaCoCo shows line/branch/method/class coverage reporting green/yellow/red lines. Argues test-first or after is optional, claims unit tests act as living docs and force testable design, and measures when to stop based on coverage metrics.
