GitHub Checks is meant to provide meaningful code coverage metrics as close to your workflow as possible. This is done by providing line-by-line coverage on your GitHub pull requests so you can access code coverage insights without leaving your code.

This feature is only available for Github users as it leverages Github Checks.

Annotations in the "Files Changed" View

Notably, lines that you add on a commit without coverage, will show up in your pull request files view with an annotation.

Hiding Annotations in the Files View

You can always hide annotations in the Github Files view by unselecting "Show annotations" in the top right of the file.

This Github feature only hides annotations by file, not for the full pull request.

Annotations in the "Checks" Tab

To see annotations, first, go to the Checks tab under any pull request.

Look for a patch status underneath the CodecovChecks dropdown.

To view coverage information in line with your code, click on the icon to the right side of the annotation.

YAML Configuration for Github Checks and Codecov

Github Checks and annotations for the patch status are enabled by default for all GitHub users. Commit Statuses have to be enabled and set up in order for checks to be present in pull requests.

Disabling Github Checks Patch Annotations via YAML

Annotations can be disabled using a flag on the top-level section of the codecov.yml file.

github_checks:
    annotations: false

Note: If GitHub checks are disabled but statuses are still set up, normal status checks will be used instead.
