tdd-workflow

To enforce a test-driven development workflow, you guide the code changes through the RED-GREEN-IMPROVE cycle. This ensures failing tests precede implementation, driving minimal viable code and quality assurance checks.

The RED-GREEN-IMPROVE cycle in test-driven development is a phased testing workflow. RED requires writing a failing test first, GREEN implements minimal viable code to pass it, and IMPROVE refactors with coverage checks.

To start the RED phase for TDD, write a failing test for your new feature or bug fix, then execute the appropriate test framework command for your project to verify the test fails before implementation.

You can use this TDD workflow for refactoring existing code, as well as feature development and bug fixes. The IMPROVE phase specifically applies refactoring discipline while maintaining coverage checks to keep tests green.

This test-driven development workflow does not require a specific testing framework. It uses framework-agnostic commands during the RED, GREEN, and IMPROVE phases to ensure tests drive implementation across different environments.

TDD requires writing a failing test before implementation to enforce fail-first testing discipline. This ensures the code change is necessary and that tests genuinely drive the minimal viable code through the RED-GREEN-IMPROVE cycle.
