FAQPage Schema

How do I plan architecture and contracts before writing production code?▼

To start TDD cycles, draft an SDD using the provided template, obtain explicit approval, then execute a disciplined Red-Green-Refactor cycle to write tests and implementation.

What is the best way to prevent late-stage refactoring for complex features?▼

This workflow applies to scenarios involving new features from scratch, system design, or upfront architectural decisions where complex features require reliable delivery and maintainability.

Can I use this SDD and TDD workflow for new features from scratch?▼

The workflow requires explicit SDD templates, approval steps, and a disciplined Red-Green-Refactor cycle to ensure correctness and maintainability throughout the development process.

How does the Red-Green-Refactor cycle work in this TDD workflow?▼

The workflow provides templates and guardrails to prevent scope creep, enforce a rigorous Red-Green-Refactor cycle, and ensure comprehensive testing coverage for complex features.
