What problem does it solve?
Enforces test-first development to prevent production code from being written without a failing test, guiding teams toward intentional design and reliable software.
Core Features & Use Cases
- Red-Green-Refactor cycle: write a failing test, observe failure, implement the minimal production code to pass, then refactor with confidence.
- Mandatory failure verification: ensure tests fail for missing functionality and that fixes are validated by running the test suite.
- Guided workflow with guardrails: structured steps, reviews, and checks that reduce risk when implementing new features or fixing bugs.
Quick Start
Write a failing test that expresses the desired behavior, run the tests to confirm failure, then implement the minimal production code to pass and finally refactor with tests still passing.
