Testing

We default to Test-driven development (TDD) where possible and keep tests focused on one responsibility at a time.

• TDD loop

TDD loop

1. Focus on one responsibility.
2. RED: define contracts and APIs without implementation.
3. RED: write exhaustive tests (they should fail initially).
4. GREEN: implement the minimum code to pass tests.
5. REFACTOR: improve general code quality.

Why this matters

The loop promotes continuous verification and encourages clean decomposition.
