Tester Skill

Test validation automatically checks that your test suite meets minimum standards like 80% line coverage, follows BDD scenarios, uses AAA structure, and includes deterministic tests. It runs after implementation to catch quality issues before code review, providing actionable improvement suggestions for gaps.

Coverage validation verifies line coverage thresholds, edge-case and error-scenario testing, test independence, clear naming conventions, and deterministic execution. It also confirms all tests pass, identifies slow or brittle tests, and generates automated reports with specific recommendations.

Yes. The Skill specifically verifies that tests adequately cover edge cases (empty, null, boundary values) and error scenarios, ensuring robustness. It identifies gaps and suggests missing test cases to improve suite completeness before deployment.

Invoke the Tester Skill after writing tests for a completed feature. It automatically reviews your entire test suite against project standards—coverage thresholds, BDD compliance, test quality—and outputs a report with improvement guidance, reducing manual review burden.

Automated test validation runs consistently without human error, checking determinism, coverage metrics, and pattern compliance instantly. Manual review is time-consuming and subjective; automation enforces measurable standards (80% coverage, AAA structure, fast execution) uniformly across all submissions.
