SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps teams safely reduce and reorganize large regression suites without losing meaningful coverage, by replacing intuition-based cleanup with evidence-based test analysis.

Core Features & Use Cases

  • Coverage fingerprinting: Identifies exactly which lines and branches each test covers so you can see unique coverage and overlap.
  • Duplicate and redundancy analysis: Clusters near-identical tests, compares execution profiles, and separates true redundancy from tests that only look similar.
  • History-driven pruning and tiering: Mines CI results for never-failing or flaky tests, then helps classify tests into smoke, core, and extended tiers based on risk and defect-catch history.
  • Safe removal workflow: Requires quarantine, human approval, observation windows, and a per-test audit log before any deletion is finalized.

Quick Start

Ask the assistant to audit your regression suite, find redundant or low-value tests, and produce a quarantine-first curation plan with an auditable deletion record.

Frequently Asked Questions about test-suite-curation

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I find redundant tests in a regression test suite?▼

Test suite curation identifies low-value tests by mining CI history for never-failing or flaky tests and applying mutation confirmation to verify defect-catch effectiveness. This replaces intuition-based cleanup with evidence-based retention decisions.

What is the best way to safely remove obsolete tests without losing coverage?▼

Test tiering classifies tests into smoke, core, and extended tiers by mining CI history for flaky or never-failing tests and evaluating defect-catch history. This history-driven pruning restructures execution based on risk and value.

Do I need per-test coverage fingerprints to restructure my test tiers?▼

Mutation testing confirms test suite value by verifying that specific tests actually catch injected defects during curation. This mutation confirmation validates whether tests flagged as redundant or low-value are truly safe to quarantine and delete.

When should I not use automated test suite pruning?▼

Duplicate detection in a test suite works by clustering near-identical tests using AST similarity and comparing execution profiles. This coverage fingerprinting distinguishes true redundancy from tests that only look similar but provide unique branch coverage.
