Status checks are based on external processes, such as continuous integration builds, which run for each push you make to a repository. You can see the pending, passing, or failing state of status checks next to individual commits in your pull request.
Anyone with write permissions to a repository can set the state for any status check in the repository.
You can see the overall state of the last commit to a branch on your repository's branches page or in your repository's list of pull requests.
If status checks are required for a repository, the required status checks must pass before you can merge your branch into the protected branch. For more information, see "About protected branches."
There are two types of status checks on GitHub:
Checks are different from statuses in that they provide line annotations, more detailed messaging, and are only available for use with GitHub Apps.
When checks are set up in a repository, pull requests have a Checks tab where you can view detailed build output from status checks and rerun failed checks.
Note: The Checks tab only gets populated for pull requests if you set up checks, not statuses, for the repository.
When a specific line in a commit causes a check to fail, you will see details about the failure, warning, or notice next to the relevant code in the Files tab of the pull request.
You can navigate between the checks summaries for various commits in a pull request, using the commit drop-down menu under the Conversation tab.
When a repository is set to automatically request checks for pushes, you can choose to skip checks for an individual commit you push. When a repository is not set to automatically request checks for pushes, you can request checks for an individual commit you push. For more information on these settings, see "Check Suites."
To skip or request checks for your commit, add one of the following trailer lines to the end of your commit message:
- To skip checks for a commit, type your commit message and a short, meaningful description of your changes. After your commit description, before the closing quotation, add two empty lines followed by
$ git commit -m "Update README > > skip-checks: true"
- To request checks for a commit, type your commit message and a short, meaningful description of your changes. After your commit description, before the closing quotation, add two empty lines followed by
$ git commit -m "Refactor usability tests > > request-checks: true"
Checks data older than 400 days is archived. As part of the archiving process GitHub creates a rollup commit status representing the state of all of the checks for that commit. As a consequence, the merge box in any pull request with archived checks that are required will be in a blocked state and you will need to rerun the checks before you can merge the pull request.
