qa-test-impact-analysis

Test impact analysis: run only the tests a change affects, and keep the regression suite lean with evidence-based test removal. The selector cuts per-PR run time; a curation agent (regression-suite-curator) reviews per-test signal and noise at quarterly and sprint grains, gated by the removal criteria.

What it installs

Skills (2)

  • regression-suite-selector

    Use when the regression suite is so large that PR-time CI is the bottleneck. Builds a CI step that runs only tests affected by the PR's changed files (from coverage maps or Bazel rdeps), plus previously failing and new tests, while a periodic full run guards against a stale map.

  • test-removal-criteria

    Use when a suite has outgrown its value and someone is about to delete tests. Sorts candidates into duplicate, tautology, trivial, dead-signal and orphan, and deletes only when all four gate conditions hold, with a written reason, coverage evidence and a named reviewer.

Subagents (1)

  • regression-suite-curator

    Use proactively for a quarterly suite review or a test-debt sprint when the regression suite has grown faster than its value. Finds duplicates, tautologies, dead-signal and orphan tests with evidence and proposes keep, fold or delete through a four-condition delete gate. Never auto-merges.

Test code review for test files only: conventions, isolation, object-model patterns, framework architecture audits, and test suite health checks. Includes a framework blueprint for new suites and a test design scorecard. Agents (test-code-critic, e2e-selector-quality-critic, framework-architecture-auditor, test-suite-health-auditor) review structure, assertions and mocking, selector fragility, framework architecture, and suite health. Production code is out of scope.
