Milliseid komponente või mooduleid te tavaliselt üksustestidega kontrollite?

Unit tests in Android are usually written to verify individual components, ensuring they work correctly in isolation from other parts of the application. Most commonly tested are:

• ViewModel — checking business logic and UI state without dependency on the Android Framework.
• Repository — checking data access logic, e.g., to databases or networks.
• Utility classes and methods — functions that perform calculations or transformations.
• Use Cases / Interactors — individual business operations.

Unit tests should not depend on the Android SDK (e.g., Activity, Fragment), for which instrumented tests are used. Unit tests help quickly identify errors in logic and ensure code stability during changes.
