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.

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.
