What problem does it solve?
This skill helps you create and review tests that provide meaningful regression evidence instead of duplicating implementation details or framework behavior.
Core Features & Use Cases
- Behavior-First Testing: Design tests around externally meaningful behavior, stable contracts, realistic inputs, and important failure paths.
- Test Structure and Placement: Follow local repository conventions, extend related coverage when appropriate, and choose the smallest effective test shape.
- Reliable Test Quality: Keep tests deterministic, isolate boundaries with focused mocks, use precise assertions, and verify that tests would catch real regressions.
- Review and Reporting: Assess test feedback, fixtures, helpers, snapshots, skipped cases, and verification evidence using practical quality criteria.
Quick Start
Ask the writing-tests skill to review the proposed tests for behavioral coverage, determinism, mock boundaries, assertion quality, and alignment with nearby repository conventions.
