Stats

The stats are calculated as following:

• Time to review: It is the time taken by a reviewer from the Pull Request publication or the last Commit push (whatever happens last) to the first time the pull request is reviewed.
• Time to review: It is the median of the times to review of all Pull Requests reviewed by a person in the period.
• Total reviews: It is the count of all Pull Requests reviewed by a person in the period.
• Total comments: It is the count of all the comments while reviewing other user's Pull Requests in the period (comments in own PRs don't count).

Integrations 🔌

Check the guide for the tool you want to integrate:

• Slack
• Microsoft Teams
• Webhooks

Troubleshooting

The action is printing an empty table.

1. Make sure the repositories have pull request reviews during the configured period.
2. When specifying repositories or organization paramaters, a Personal Access Token is required in the token parameter.
3. If providing a Personal Access Token, make sure it has the repo permission for the projects you want.

I get the error "Error commenting on the pull request...".

This error happens when the action's permissions are configured as read by the organization. To fix it, overwrite them by adding a permissions configuration in the workflow file. The minimum required permissions are contents: read and pull-requests: write:

jobs:
stats:
  runs-on: ubuntu-latest
  permissions:
    contents: read
    pull-requests: write
  steps:
    - name: Run pull request stats
      uses: Sportsbet-Internal/pull-request-stats@master
