Codecov от Sentry

The Code Coverage browser extension makes it easy to identify needed test areas by showing you absolute coverage and coverage changes overlaid with your code right in GitHub

Once installed, get:

• Line coverage information while viewing commits and single files
• Line coverage information and coverage totals on Pull Requests
• The ability to filter coverage using Flags and Components directly in the GitHub UI

Pre-requisites:
* Must use either Firefox or Google Chrome web browsers.
* Must have GitHub's Global navigation update enabled

The extension uses your logged-in session to determine what repos you can access. Please make sure to log in to Codecov using your web browser to view coverage data. Alternatively you can use a Codecov API token.

The extension may collect and use information from your browser such as your IP address and the URLs of the pages you access on https://github.com or on an enterprise version or self-hosted installation of Github you explicitly grant the extension access to.
