Gitlab merge request code review integration
You can set your merge requests to require approval before they can be merged. While all users with Developer or higher permissions in GitLab Free can approve merge requests, these approvals are optional. GitLab Premium and GitLab Ultimate give you even more options: Show
Before work can be merged, establish the necessary rules regarding the number and type of approvers. Create a list of users who act as code owners for specific files and require their approval before merging work. Merge request approvals can be configured per project and at the group level. Administrators of self-managed GitLab Premium and GitLab Ultimate instances can also configure approvals for the entire instance. Merge request approval rules in GitLabYou can set the minimum number of approvals required before code can be merged into your project using merge request approval rules. You can also use these rules to specify which users can approve work. Here are some examples of rules you can write:
You can also customize your rules to have additional merge request approval settings for greater control over the level of oversight and security your project requires. How to approve a merge request in GitLab?When an eligible approver visits an open merge request, GitLab displays one of the following buttons after the merge request body:
When adding a comment to a merge request, eligible approvers can also use the /approve quick action. If a user approves a merge request and is listed in the reviewer list in GitLab 13.10 or later, a green check mark () appears next to their name. A merge request can merge once it has received the number and type of approvals you specify unless it is blocked for another reason. Other issues, such as merge conflicts, pending discussions, or a failed CI/CD pipeline, can block merge requests. Prevent author approval in your project's settings to prevent merge request authors from approving their own merge requests. When you enable approval rule overrides, merge requests created before the default approval rules change are unaffected. The only exceptions are changes to the rule's target branch. You can find more detailed information in the Merge Request Approval section of the GitLab documentation. GitLab reviewersSet up GitLab default reviewers automaticallyGitLab does not provide a way to automatically set reviewers on new merge requests, but you can ease this process by implementing code owner rules (next chapter). GitLab code owners for merge requestCreate a CODEOWNERS file to specify which users or shared groups are in charge of which files and directories in a repository. Each repository can only have one CODEOWNERS file. To set up your file: Select the location where you want to save your CODEOWNERS file and create it, you have three possibilities:
Enter commands in the file that follows one of the following patterns:
After setting up your CODEOWNERS file, you will be able to find any potential reviewers in your eligible reviewer's section. More information about Code Owner in the dedicated GitLab documentation. GitLab auto assign reviewersGitLab does not have a built-in feature to automatically assign reviewers. They tweaked another open-source project to receive recommendations for reviewers inside their merge requests. They are using the Danger bot and applied some personal workflows to it (you can find more information about that in Reviewer roulette one year one). Most other code versioning or code hosting software has a dedicated review feature within their pull/merge request. GitLab does not. Inside GitLab, you can either approve a pull request or revoke your approval. If you wish to request changes to another developer, you need to either leave a comment in the GitLab code review workflowThe GitLab code review workflow is simple.

How do review apps work?A Review App is a branch-to-environment mapping. Access to the Review App is made available via a link on the branch's merge request. The following is an example of a merge request with a dynamically set environment. A branch was successfully built in this example and deployed in a dynamic environment accessible by selecting the View app. Following the addition of Review Apps to your workflow, you follow the branched Git flow. That is, push a branch and let the runner deploy the Review App based on the dynamic environment job's script definition. Then, the runner will build and deploy your web application. To view the changes live, select the link in the merge request related to the branch. You have now set up a new review environment! If you're interested, you can learn more in the dedicated GitLab Review App Documentation section. Why are review apps important?GitLab review apps for developersDevelopers can begin collecting feedback much sooner. Submit a merge request and test your changes in real-time. When you push to master, you'll know that your changes have gone through CI testing as well as a live review where the team can ensure that everything works as expected. GitLab review apps for the design, product, and marketing teamGiving feedback to designers, product managers, marketing colleagues, and others has never been easier. To preview changes, you won't need to check out branches or set up a staging environment. With Review Apps, you can see the live changes by clicking a link. Hopefully, this means you'll be able to provide more timely and accurate feedback. Axolo is a Slack app to help techteams review merge request seamlessly3. GitLab CI/CD & automatic deploymentGitLab developed an internal CI/CD tool for software development following the continuous methodologies:
Continuous Integration works by pushing small changes to your application’s codebase hosted in a Git repository, and, to every push, run a pipeline of scripts to build, test, and validate the code changes before merging them into the main branch. Continuous Delivery and Deployment consist of a step further CI, deploying your application to production at every push to the default branch of the repository. These methodologies allow you to catch bugs and errors early in the development cycle, ensuring that all the code deployed to production complies with the code standards you established for your app. For more detailed information on GitLab CI/CD, you can watch a Demo: CI/CD with GitLab made by the GitLab team or surf through the CI/CD Documentation. How to review code for a GitLab merge request?Review a merge request. Go to the merge request you want to review, and select the Changes tab. ... . Select Add a comment to this line ( ) in the gutter to expand the diff lines and display a comment box. ... . In the text area, write your first comment, then select Start a review below your comment.. Does GitLab have code reviews?Every code review starts with a merge request. The merge request allows team members, reviewers and approvers to collaborate with each other. Diff shows the changes alongside the original code - helping reviewers identify changes with ease. How do I review and merge pull requests?Merging a pull request. Merge all of the commits into the base branch by clicking Merge pull request. ... . Squash the commits into one commit by clicking the merge dropdown menu, selecting Squash and merge and then clicking Squash and merge.. What is a process of code review by other developers followed by a merge operation?After a software developer has completed coding, a code review is an important step in the software development process to get a second opinion on the solution and implementation before it's merged into an upstream branch like a feature branch or the main branch. |
