tdd-workflow

The RED-GREEN-REFACTOR cycle is the core test-driven development workflow of writing a failing test, implementing minimal code to pass it, and then refactoring. It enforces a test-first approach to clarify requirements and reduce defects.

To start writing tests first during feature development, write a failing test that defines the desired behavior, then implement only enough production code to make it pass, and repeat this cycle to build reliable code.

Yes, you can use this test-first workflow for bug fixes and refactoring processes. It guides structured code evolution by enforcing clear phase rules, improving confidence and code quality across your software team.

The best way to enforce TDD phase rules is to automate the RED-GREEN-REFACTOR cadence. This ensures developers write tests first and implement minimal production code, driving disciplined code evolution.

Writing minimal production code to pass tests improves code quality because it prevents over-engineering and ensures every line of code is backed by a test-first requirement, accelerating feedback and clarifying requirements.

A strict test-driven development workflow may not suit exploratory prototyping where requirements are highly volatile. It requires a clear understanding of desired behavior upfront to write effective failing tests before implementation.
