test-driven-development

The Red-Green-Refactor cycle in test-driven development requires writing a failing test first, implementing the minimal code to make it pass, and then refactoring. This repeatable process ensures code quality and prevents regressions.

To start writing new features using TDD methodology, write a failing test for the desired functionality first. Then, write the minimal implementation code required to make that test pass before moving into the refactoring phase.

Yes, you can use test-driven development for bug fixes and refactoring existing code. The methodology applies to all software development tasks, ensuring you write failing tests that capture the bug before implementing the fix.

Test-first development prevents software regressions by enforcing strict testing principles before implementation. By requiring a failing test prior to writing code, it ensures all new functionality is verified and maintains code reliability.

No specific testing frameworks are required to follow the TDD methodology. The process enforces the Red-Green-Refactor cycle and strict testing principles applicable across all software development environments without external dependencies.
