SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Writing consistent, well-scoped tests is often skipped or done inconsistently during AI-assisted development. This Skill provides a structured testing mode that enforces project testing standards, scopes test runs to changed files, and produces documented test summaries.

Core Features & Use Cases

  • Scoped Test Execution: Runs only tests relevant to changed files rather than the entire suite, with configurable commands for full, specific, and coverage runs.
  • Test Authoring Guidance: Provides priorities for unit and integration tests, covering happy paths, error states, edge cases, and invalid inputs.
  • Hard-to-Test Code Strategy: Offers a seam ladder (pure helper, injectable adapter, module mock, integration test) plus characterization tests for legacy code and a coverage-debt ledger.
  • Use Case: After implementing a new feature, invoke this Skill to author tests for the changed modules, run them with coverage, and generate a versioned test summary in docs/4-unit-tests/.

Quick Start

Ask the AI to enter testing mode and write tests for the authentication module, then run the relevant test suite with coverage.

FAQPage Schema
How do I write unit tests for a new feature with an AI coding agent?

Invoke testing mode with the component or feature name as the argument. The agent reads your architecture and testing docs, then authors tests covering happy paths, error states, edge cases, and invalid inputs for the changed files.

How do I test legacy code that is hard to test?

Use the seam ladder approach: start with the cheapest option from exported pure helper, injectable client or adapter, module mock, to integration test. Before refactoring legacy code, pin current behavior with characterization tests.

Should I run the whole test suite after a small change?

No. The testing guidelines scope runs to only the tests relevant to files that changed, focusing on the new feature, fix, or refactor rather than the entire project suite.

What is coverage debt and how do I track it?

Coverage debt records uncovered risky paths as one-line entries in docs/4-unit-tests/COVERAGE-DEBT.md with the path, why it is hard to test, and an escape plan. Delete a line in the same change that gives its path meaningful coverage.

When should I use this testing skill instead of the implement workflow?

Use it standalone for test backfill or coverage work outside an implementation session. During feature implementation, the TRIP-2-implement testing gate points here automatically for deep test-authoring work.
