SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Quickly identify and prioritize potential breakages caused by a code change, enabling targeted regression testing before merge.

Core Features & Use Cases

  • Analyzes diffs to surface affected features, routes, components, and data queries.
  • Produces a prioritized regression test checklist spanning databases, shared utilities, API endpoints, and UI components.
  • Use Case: Before merging a PR that touches core models or data flows, surface the most risky areas to re-test first.

Quick Start

Run the regression-check workflow on your branch to generate a focused regression test plan.

Frequently Asked Questions about regression-check

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

FAQPage Schema
How do I identify regression testing scope from a code diff?▼

To prioritize regression testing, classify the blast radius of code changes by tracing diffs to routes, components, database queries, and shared utilities. This surfaces affected callers and high-risk areas to guide focused validation.

What is blast radius analysis in regression testing?▼

Blast radius analysis classifies the potential breakage impact of a code change by tracing diffs to shared utilities, API endpoints, and UI components. It produces a prioritized regression test checklist to drive focused validation.

How do I generate a regression test checklist before merging a pull request?▼

Generate a regression test checklist before merging by analyzing branch diffs against database models, shared utilities, API endpoints, UI components, and configuration. The analysis captures change context and recommends a retest scope.

Can I use diff analysis to forecast API endpoint breakage?▼

Yes, diff analysis forecasts API endpoint breakage by tracing code changes to affected routes and data queries. It identifies features most at risk of breaking and recommends targeted retests before merge.

Does regression testing work for changes to database models and shared utilities?▼

Regression testing works for database models and shared utilities by tracing diffs to affected data queries and downstream callers. It captures change context and classifies impact to produce a prioritized validation checklist.
