Our Pull Request Approval Process

We have these basic policies to make the approval process smoother for our volunteer team.

Testing Your Code

Please make sure your code passes all tests. Our test code coverage system will fail if these conditions occur:

1. The overall code coverage drops below the target threshold of the repository
2. Any file in the pull request has code coverage levels below the repository threshold
3. Merge conflicts

The process helps maintain the overall reliability of the code base and is a prerequisite for getting your PR approved. Assigned reviewers regularly review the PR queue and tend to focus on PRs that are passing.

Reviewers

Do not assign reviewers. Our Queue Monitors will review your PR and assign them.
When your PR has been assigned reviewers contact them to get your code reviewed and approved via:

1. comments in this PR or

2. point of contact for evaluating the validity of your work
3. person who verifies matching issues by others that should be closed.
4. person who gives general guidance in fixing your tests

CONTRIBUTING.md

Read our CONTRIBUTING.md file. Most importantly:

1. PRs with issues not assigned to you will be closed by the reviewer
2. Fix the first comment in the PR so that each issue listed automatically closes
