This skill helps developers implement test-driven development by guiding the Red-Green-Refactor cycle across software features, improving code quality and design.
Start a TDD session for a feature by invoking the workflow, write a failing test, run the Green phase, then perform Refactor and repeat for the cycle.

Test-driven development using the Red-Green-Refactor cycle involves writing a failing unit test, implementing the minimum code to pass it, and then refactoring. This skill guides you step-by-step through each phase to improve code quality and design.
The best way to start a TDD workflow is to invoke a structured session, write a failing test for the target feature, run the Green phase to implement functionality, and then perform refactoring. This iterative cycle accelerates feature development and learning.
Yes, this TDD workflow applies to both unit tests and integration tests. It provides reusable templates and best practices to structure your Red, Green, and Refactor phases across iterative testing scenarios in real software projects.
Yes, you need standard tooling like Node.js and a test runner such as vitest to execute and validate tests. The skill requires these dependencies to run the test-driven development workflow and verify your code during the Green phase.
Skipping the Refactor phase during test-driven development often leads to poorly designed code. This skill enforces the complete Red-Green-Refactor cycle, ensuring you iteratively clean up and improve code structure while maintaining passing tests.
The Red-Green-Refactor cycle is less suited for exploratory prototyping where immediate functionality is prioritized over test coverage. It is designed for disciplined test-first development across defined unit and integration testing scenarios.
