Testing

Test-driven by default. Prove the problem before solving it.

Core Workflow: Bug First

1. Reproduce — Run the failing scenario and observe the actual behavior
2. Write a failing test — Minimal reproduction as a test case
3. Commit the failing test — Use Skill(commit) with message like test: reproduce #issue-description
4. Fix the code — Only now attempt the fix
5. Verify — Run pnpm test and confirm the test passes
6. Commit the fix — Separate commit from the test

This applies to all bug fixes. The failing test proves the bug exists and prevents regressions.

Fixture Tests

Noodle uses directory-based fixtures in testdata/. Read references/fixtures.md for full format, helper API, and code patterns.
