FAQPage Schema

What is TCRDD and how does it differ from standard TDD?▼

TCRDD (Test-Driven Commit || Revert + Test Driven Development) extends standard TDD by enforcing a strict Red, Green, and Refactor workflow using git-gamble commands to automatically commit passing tests or revert failing code changes.

How do I implement the three phases of Test-Driven Development?▼

To implement Test-Driven Development, follow the three phases: write a failing test (Red), write the minimum code to pass it (Green), and clean up the code without changing behavior (Refactor). This Skill provides examples and a review checklist for compliance.

What are the common mistakes when doing test-first development?▼

Common test-first development mistakes include skipping the Refactor phase, writing too much code before testing, and ignoring test failures. This Skill addresses these pitfalls and offers a review checklist to ensure strict TDD compliance.

Can I see code examples for applying TDD in TypeScript?▼

Yes, this Skill provides TypeScript code examples demonstrating Test-Driven Development in practice, illustrating how to correctly apply the Red, Green, and Refactor cycles within the TCRDD workflow.

When should I use the git-gamble command in the TCRDD workflow?▼

Use the git-gamble command during the TCRDD workflow to enforce the Commit || Revert mechanism, automatically discarding code changes if tests fail and committing them when tests pass, ensuring continuous test-driven compliance.
