Which feature of GitLab enhances the development process by integrating code review?

The feature that enhances the development process by integrating code review is Review Apps. This feature creates temporary, disposable environments for every new branch or merge request in GitLab. By doing so, it allows developers and stakeholders to preview and interact with the changes in a fully functional environment before they are merged into the main codebase.

This capability greatly improves the code review process. Review Apps provide a tangible view of the changes, enabling reviewers to test the application and provide feedback based on actual usage rather than just theoretical code review. As a result, teams can ensure the functionality meets their requirements and standards, fostering better communication and collaboration during the review process.

Other features such as deployment automation streamline the process of deploying code but do not directly involve code review. Issue tracking helps with managing tasks and bugs but is not specifically focused on the review of code. Version control management is essential for tracking changes in the codebase, but it does not specifically facilitate the review process in the same way that Review Apps do.
