How do I manage dependencies in Clean Architecture?

How do I manage dependencies in Clean Architecture?

In Clean Architecture, dependencies should point inwards, meaning that higher-level modules should not depend on lower-level modules. You can achieve this by using interfaces and dependency injection.

Can you explain dependency injection and how it fits into this?

Dependency injection is a design pattern that allows a class to receive its dependencies from an external source rather than creating them itself. This promotes loose coupling and makes your code more testable.

What are some common tools or frameworks for implementing dependency injection?

Common tools include Spring for Java, Dagger for Android, and .NET Core's built-in dependency injection. Each has its own way of managing dependencies.

How do I test components with dependency injection?

You can easily test components by mocking their dependencies. This allows you to isolate the component and verify its behavior without relying on the actual implementations of its dependencies.
