What are the best practices for implementing the repository pattern?

The repository pattern is a design pattern that helps manage data access. Best practices include: 1. Keep your repositories focused on a single entity. 2. Use interfaces to define repository contracts. 3. Implement unit of work to manage transactions. 4. Avoid business logic in repositories.

Can you explain why using interfaces is important?

Using interfaces allows for better abstraction and decoupling of your code. It makes it easier to swap out implementations, facilitates testing with mocks, and enhances maintainability.

What is the unit of work pattern?

The unit of work pattern is a design pattern that maintains a list of objects affected by a business transaction and coordinates the writing out of changes. It helps manage transactions and ensures that all changes are committed or rolled back together.

How do I test my repository implementations?

You can test your repository implementations by using mocking frameworks to create mock objects for your data sources. This allows you to verify that your repository methods are called correctly without needing a real database.
