15. Unit Testing and Test-Driven Development (JUnit, Mockito)

Unit Testing and Test-Driven Development (TDD) are essential practices in modern software development to write clean, maintainable, and error-free code. Utilizing frameworks like JUnit and Mockito, developers can create automated tests and mock dependencies effectively. This methodology fosters better design decisions, early bug detection, and enhanced code quality through well-tested modules.
