Action Summary

Test-Guard is a GitHub Action designed to evaluate whether a pull request (PR) includes adequate test coverage for the changes made, going beyond basic code coverage percentages. It automates the process by combining diff coverage analysis, heuristic test-file matching across multiple programming languages, and AI-powered per-file evaluation to provide a definitive pass/fail verdict on testing adequacy. This action helps teams ensure robust testing practices and streamline code review by identifying untested or inadequately tested changes.

What’s Changed

🧪 Test-Guard

A GitHub Action that gates pull requests on test adequacy. Three layers — coverage analysis, heuristic file matching across 19 languages, and AI-powered per-file evaluation — so untested code stops slipping through review.

Quick Start

- uses: ostico/test-guard@v1
  with:
    coverage-file: coverage.xml

No external API keys needed — uses the GitHub Models API with your existing GITHUB_TOKEN.

What’s New in v1.4

🎯 TL;DR Verdict at the Top

Reports now open with a one-line outcome so you know the result instantly:

✅ PASS — All changes are adequately tested.
⚠️ WARNING — Test coverage has minor gaps — review recommended.
❌ FAIL — Insufficient test coverage — tests must be added or updated.

🏷️ Human-Readable Layer Names

No more internal jargon. Reports now say Coverage Analysis, Test File Matching, and Per-File Evaluation instead of Layer 1/2/3.

🧹 Cleaner Pipeline

  • Non-source files (configs, docs, lockfiles) are pre-filtered before reaching Layer 1 — no more vacuous “100% coverage” on files that were never in the coverage report.
  • Honest messaging when no source files appear in coverage data.

✂️ Concise AI Reasons

AI verdicts now produce short, actionable reasons (max 15 words per file) instead of lengthy explanations.
