CODEOWNERS Coverage Extended

An Action that checks if files are covered by the CODEOWNERS file.

Forked from sibipro/codeowners-coverage to add PR comment support and debug logging improvements. sibipro/codeowners-coverage is itself a fork of austenstone/codeowners-coverage, which is no longer actively maintained.

Changes from sibipro fork

• PR comments — New comment-on-pr input to post/update a comment on PRs listing uncovered files with coverage percentage. The comment is automatically updated when all files become covered.
• Debug logging — Verbose output (file lists, glob patterns) is now gated behind debug mode instead of always logging.

Usage

Create a workflow (eg: .github/workflows/seat-count.yml). See Creating a Workflow file.

Example

name: CODEOWNERS
on:
  workflow_dispatch:

jobs:
  run:
    name: Run Action
    runs-on: ubuntu-latest
    steps:
      - uses: marcofranzen99/codeowners-coverage@v2.0

Example with PR comment

Post a comment on pull requests listing files not covered by CODEOWNERS.

name: CODEOWNERS
on:
  pull_request:

permissions:
  pull-requests: write

jobs:
  run:
    name: Check Coverage
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - uses: marcofranzen99/codeowners-coverage@v2.0
        with:
          comment-on-pr: 'true'
