AADC Exam Toy App

A toy app created when preparing for the AADC Exam

Core Features

• Implement the MVVM Architecture Pattern
• Mediate data operations with the Repository Pattern
• Observe and respond to changing data using LiveData.
• Persist data with Room
• Manage long-running tasks with Kotlin coroutines
• Handle app navigation with Navigation Component and SafeArgs
• Display Menus and handle menu-based navigation
• Add a navigation drawer and implement drawer navigation
• Schedule Notifications with WorkManager
• Bind local data to a RecyclerView list using the Paging Library
• Handle user preferences with a Settings screen and SharedPreferences
• Use the Service Locator design pattern to handle class dependencies.
• Build local unit tests for the repository using test doubles (a fake local data source)
• Build local unit test for the existing app view models using test doubles (a fake repository), since almost each view model depends on a tasks repository.
• Add local instrumented tests for Room's DAO and integration tests for the local data source.
• Add integration tests for fragment-view models pairs using test doubles (a fake repository), Mockito to mock the NavController, and Espresso to test the UI
• Add end to end tests to test the app as a whole and the app navigation
