Test GitLab merge requests before they merge

Teams using GitLab.com or GitLab Self-Managed can now build merge requests and test proposed merges against their target branches with merged-results builds. Merge request builds test the source branch, while merged-results builds test the proposed merge, helping catch integration failures before merging. Set up merge request builds In your pipeline’s GitLab settings: Enable Build merge requests to build a merge request when it opens or receives new commits.
