SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill runs the existing test suite to detect regressions after changes, reporting PASS/FAIL outcomes without modifying Linear or kanban states.

Core Features & Use Cases

  • Auto-detect test framework and test directories
  • Run full test suite within a controlled timeout
  • Output a verdict with counts and failing excerpts
  • Post a Linear comment with a concise summary
  • Supports multiple languages and test frameworks via MCP Ref integration

Use Case: Before merging a feature, automatically run the complete test suite and share a regression summary with stakeholders.

Quick Start

Execute ln-502-regression-checker to auto-detect framework, run the full test suite, and return a verdict JSON along with a Linear comment.

Frequently Asked Questions about ln-502-regression-checker

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

FAQPage Schema
How do I automatically detect and run tests across Python, JavaScript, and Go projects?▼

Regression detection automatically discovers your test framework and directories, then runs the full test suite across Python, JavaScript, and Go projects within a timeout. It returns pass/fail counts and key failures without modifying your project state.

Can I run regression tests in CI without changing Linear or project status?▼

Yes. The regression checker executes your complete test suite and posts results as a Linear comment with a concise summary, reporting pass/fail outcomes without altering any Linear states or kanban boards.

What happens if my test suite doesn't finish within the timeout?▼

The regression checker enforces a controlled timeout for test execution. If the suite exceeds this limit, it halts and returns the verdicts collected up to that point, preventing indefinite CI delays.

How do I integrate regression testing into my CI workflow?▼

Execute the regression checker in your CI pipeline to auto-detect test frameworks, run the full suite, and generate a verdict JSON with pass/fail metrics and failing excerpts. Results post directly to Linear.

Does regression detection work with multiple test frameworks in the same project?▼

The regression checker auto-discovers and runs test frameworks present in your project. It supports multiple languages and frameworks via MCP Ref integration, handling framework detection across Python, JavaScript, and Go automatically.
