Which feature in GitLab helps in resolving merge conflicts?

The feature that helps in resolving merge conflicts in GitLab is the Merge Request. When developers work on multiple branches simultaneously, they may make changes to the same part of the codebase. When one branch is merged into another, GitLab attempts to automatically integrate those changes. However, if there are conflicting changes that cannot be automatically resolved, GitLab highlights these merge conflicts in the Merge Request interface.

This specialized interface provides functionalities that allow developers to view conflicting files side-by-side, understand the differences between branches, and manually edit the code to resolve the conflicts directly within GitLab. After resolving the conflicts, developers can finalize the merge, ensuring that the codebase remains stable and functional.

Other options do not directly address the need for resolving merge conflicts. Inline Editing is primarily used for quick changes within the interface but does not facilitate merge conflict resolution. The Approval Workflow is designed to implement governance over code changes through reviews and approvals but does not assist in resolving conflicts. Branch Comparison is useful for seeing the differences between branches but does not provide tools for resolving conflicts. Thus, the Merge Request stands out as the key feature that specifically addresses merge conflicts in GitLab.
