As software developers, we’ve all come across various principles, methodologies, and philosophies throughout our careers — things like SOLID, DRY, and KISS, to name a few. But when I reflect on what truly defines code quality, it’s often the simplest yet most impactful principles that make the biggest difference.

Writing clean, testable, and maintainable code isn’t just about making life easier in the moment; it’s crucial for the long-term success and sustainability of the software we build. These principles naturally align with the Test-Driven Development (TDD) approach and have a significant impact on the quality of the software we create.

One cannot emphasize more on testing in programming. It provides fast feedback, reduces bugs, and supports clean design principles like loose coupling and high cohesion. Automated tests catch regressions early, allowing developers to refactor code with confidence, reducing technical debt over time. Writing testable code often leads to more modular, maintainable systems, and testing critical areas, especially those with complex logic, is key to avoiding future issues. By requiring tests for bug fixes and promoting automated testing, teams can foster a culture of continuous improvement…
