repository-pattern

To decouple game logic from data storage, implement the repository pattern using a generic interface. This abstracts data operations, allowing you to swap backends without altering domain logic.

The best way to mock game data access for TDD is using an in-memory repository implementation. It provides a generic interface that enables easy mocking of CRUD operations for unit testing.

Yes, you can use a single generic repository interface for local JSON and cloud saving. Backend agnosticism allows switching data sources later without changing the core game systems.

The repository pattern improves testability by abstracting data sources via generic interfaces. This enables easy mocking of data access, keeping business logic isolated and testable.

Implementing a generic data access layer relies on SOLID principles to decouple data access from business logic. This ensures your systems remain maintainable and easy to modify.

Avoid the repository pattern for data access abstraction if your project is small and tightly coupled logic is acceptable. Overhead outweighs benefits when complex backend swapping is unnecessary.
