What problem does it solve? Running tests across unit, integration, and E2E layers while manually verifying that every acceptance criterion is covered by passing tests is tedious and error-prone. This Skill automates test execution, result collection, and traceability validation, producing a structured test report. ## Core Features & Use Cases - Layered Test Execution: Runs UT, IT, and E2E suites in order, auto-detecting frameworks like Jest, Vitest, pytest, and Go test. - Traceability Verification (--trace): Maps test results back to acceptance criteria from the test-case documents, flagging uncovered ACs and orphan tests. - Affected-Test Selection (--affected): Uses git diff to identify changed files and runs only the tests associated with them. - Use Case: After a batch development run, invoke the skill with --trace to execute the full suite and generate docs/devdocs/05-test-report.md showing pass rates, coverage, and AC traceability status. ## Quick Start Ask the AI to run the full test suite with traceability verification and generate the test report.
