Repository Testing with Fakes, Stubs, and API Failure Simulation: Android Unit Testing - Part 15

In this video, we continue exploring Android unit testing by enhancing the resilience of the CountryRepository when integrating both local (DAO) and remote (Service) data sources.

The tutorial demonstrates how to:
• Handle real-world scenarios like API failures and network issues
• Implement error handling using try-catch blocks
• Create and use different types of test doubles including stubs, fakes, and throwing stubs for the service layer
• Refactor and test the repository to ensure fallback to local data when remote service fails
• Write unit tests to validate scenarios with empty and pre-populated local databases
• Apply parameterized testing to reduce redundancy in test cases

This video provides practical techniques for building robust and testable repositories in Android applications using Kotlin and coroutines.
