SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Enforces a test-first approach to development, ensuring code correctness by requiring failing tests first and guiding red-green-refactor cycles to prevent regressions.

Core Features & Use Cases

Test-first discipline: Enforces writing a failing test before any implementation.
Minimal viable implementation: Implement only enough code to pass the tests, reducing overengineering.
Safe refactoring: Refactor with confidence while preserving behavior and coverage.
Broad applicability: Suitable for business rules, state transitions, and complex data transformations across languages.

Quick Start

Ask the AI to start a TDD cycle for the next feature by writing a failing test first and then implementing the minimal code to pass.

FAQPage Schema

How do I automate test-driven development cycles for feature implementation?▼

Automate test-driven development cycles by enforcing a test-first workflow that writes failing tests, implements minimal code to pass, and refactors safely to prevent regressions. This ensures correctness through iterative red-green-refactor feedback.

What is the red-green-refactor workflow in test-first software development?▼

The red-green-refactor workflow in test-first development means writing a failing test, implementing minimal code to pass it, then refactoring while preserving behavior. This cycle prevents regressions and reduces overengineering during feature implementation.

Can I use test-driven development for state transitions and business rules across multiple languages?▼

Yes, test-driven development supports state transitions, business rules, and complex data transformations across multiple languages. It applies automated test scaffolding to ensure high confidence during feature development, debugging, and code reviews.

How do I start a TDD cycle when writing new code?▼

Start a TDD cycle by writing a failing test for the next feature before any implementation. Run the test to observe the failure, then implement only enough minimal code to pass the test, and finally refactor while maintaining behavior and coverage.

What's the best way to prevent regressions while refactoring complex logic?▼

The best way to prevent regressions while refactoring complex logic is using test-driven development to maintain behavior and coverage. Safe refactoring is enforced by running automated tests iteratively throughout the red-green-refactor cycle.

When should I not use a test-first approach for software engineering tasks?▼

A test-first approach is not suited for trivial logic lacking non-trivial business rules or state transitions. Test-driven development provides the most value during feature development, debugging, and code reviews requiring automated test scaffolding and iterative feedback.
