test-driven-development

You enforce test-driven development by following a strict RED-GREEN-REFACTOR cycle, writing a failing test first and then implementing minimal production code to pass it. This ensures code is only written after a failing test is identified.

The RED-GREEN-REFACTOR cycle requires writing a failing test, implementing minimal code to pass it, then refactoring. For bug fixes, you first write a test that reproduces the bug, confirming it fails before applying the fix to reach green.

Yes, this approach explicitly supports pytest workflows and integrates with common automated testing frameworks. It is language-agnostic when applied within a test-driven workflow across different repositories.

You need a test framework and code under test to start writing tests before production code. The workflow requires an automated testing setup to observe failing tests and validate minimal code implementations.

Yes, you can apply the RED-GREEN-REFACTOR process to refactoring existing code. It guides teams through ensuring tests remain green while improving code quality, reliability, and maintainability during refactors.

The best way to maintain TDD discipline is to follow a repeatable RED-GREEN-REFACTOR process for feature development. Write a failing test first, observe it fail, then implement the minimal code to pass before refactoring.
