Dependency Injection (DI) is a design pattern used in software development that allows a program to achieve Inversion of Control (IoC) by injecting dependencies into a class rather than having the class create its own dependencies. This promotes loose coupling and enhances testability and maintainability of the code.
Key Benefits of Dependency Injection:
Decoupling: Classes are less dependent on concrete implementations.
Easier Testing: You can easily replace dependencies with mocks or stubs.
Improved Maintainability: Changes in dependencies require less modification in the code.
