Test Driven Development (TDD) is a software development approach where tests are written before the actual code. The cycle includes writing a failing test, implementing the code to pass the test, and then refactoring the code to improve quality, all while ensuring the test passes. Importance of Test Driven Development (TDD) Improved Code Quality: TDD ensures that code is written with clarity, reducing errors and ensuring it meets expectations. Early Bug Detection: By writing tests first, bugs are caught early, saving time and reducing future costs. Better Maintainability: TDD encourages refactoring, leading to simpler, more maintainable code. Faster Development: With fewer bugs and clearer structure, TDD accelerates development in the long run. Supports Agile: TDD integrates seamlessly into Agile workflows, allowing for rapid feedback and continuous improvement. In short, Test Driven Development ensures high-quality, reliable software and is an essential practice for modern software development.
