test-driven-development

Test-driven development is implemented by following the Red-Green-Refactor cycle: writing a failing test first, creating minimal code to pass it, and then refactoring. This ensures robust, verifiable code and prevents regressions from the outset.

The Red-Green-Refactor cycle in TDD mandates writing a failing test (Red), writing minimal production code to pass that test (Green), and subsequently refactoring the code. This strict methodology ensures high code quality and immediate test coverage.

You should use TDD when starting any new feature or bug fix to ensure test coverage from the outset. Writing tests before production code prevents bugs and improves code quality by enforcing a rigorous, verifiable software development workflow.

TDD works for refactoring in agile workflows by ensuring that all refactored code is guided by passing tests. The methodology enforces writing failing tests before changes, guaranteeing that refactoring improves code quality without introducing regressions.

No specific testing frameworks are required as dependencies. This TDD methodology operates independently to enforce the Red-Green-Refactor cycle, focusing on the software development process rather than mandating particular testing tools or environments.
