Test Driven Development (TDD) is a methodology that flips traditional software development on its head.
TDD introduces a radical yet powerful approach: write tests first, then write the code to pass those tests.
TDD follows a simple yet powerful cycle: Red, Green, Refactor.
TDD's benefits include superior code quality, early bug detection, confidence in refactoring, clear requirements and design, and collaborative documentation.
TDD aims to improve the quality of the code from the ground up by emphasizing clean, modular, and maintainable code.
TDD detects bugs early, not when the code goes to production, reducing debugging time.
TDD improves code reliability with its comprehensive test suite acting as a safety net and continuous code improvement.
TDD is universal and can be applied to any project of any size or complexity and any technology stack or programming language.
Behaviour Driven Development (BDD) extends TDD's principles and focuses on behavior and business value.
