Timely and constructive feedback in the pull request (PR) flow is essential to maintaining code quality and fostering a culture of continuous improvement. Without effective feedback mechanisms in place, the PR process can become a bottleneck, hindering the swift delivery of new features and bug fixes.

We’ve updated our Coverage pipeline to deliver reliable coverage results on your pull requests much faster. To see how it works, users can opt-in to our new Diff Coverage check.

How It Helps You

This feature adds a new report to your PRs that shows whether your diff coverage is up to standards based on the quality gate rules you’ve set for your repository. If the coverage doesn’t meet your standards, you can block merging pull requests until they are.

You can try the new Diff Coverage check by enabling it on the repository settings (GitHub only for now).

The diff coverage of a PR is the percentage of coverable lines that the pull request added or modified that are covered by tests. This makes it easy for your team to see which new or updated lines need to be tested before they’re merged.

How It Works

To set up Diff Coverage and try the new check, you can follow the instructions found in this earlier blog post or check out this quick video:


The improvement of our Coverage pipeline is an ongoing process that we’re incredibly excited about. Our plan is to continue migrating our Coverage features to rely on the new pipeline, so we can deliver detailed, reliable, and fast coverage feedback to your PRs.
