What is the Impact of Test Driven Development on Code Maintenance? Test Driven Development (TDD) significantly improves code maintenance by ensuring the code is reliable and easy to update. Writing tests before the code helps catch issues early, making it easier to fix bugs and prevent new ones during future updates. TDD also encourages refactoring, allowing developers to improve code without breaking existing features. Overall, test driven development enhances code maintenance, making the software more scalable, maintainable, and easier to modify over time. https://www.samyak.com/news-post/test-driven-development/
