Best Practices for Creating Merge Requests

A Step-by-Step Guide on Creating Merge Requests in GitLab

Keep Merge Requests Small and Focused

When creating merge requests in GitLab, it is important to keep them small and focused. This ensures that the review cycle is tight and focused, allowing for faster iteration and a higher velocity of work. By keeping merge requests small, you can easily track and manage changes, making it easier for reviewers to provide feedback and for you to make iterative changes.

To achieve this, follow these best practices:

  • Break down large changes into smaller, manageable chunks: Instead of making a single large merge request, consider breaking it down into smaller, more focused ones. This allows for easier review and reduces the risk of introducing errors.
  • Focus on a single objective: Each merge request should have a clear objective or goal. Avoid combining unrelated changes in a single request to maintain clarity and avoid confusion.
  • Communicate with your team: Before creating a merge request, communicate with your team to ensure that everyone is aligned on the changes being made. This helps in avoiding duplication of work and ensures that the merge request is in line with the project’s goals and standards.

Remember, keeping merge requests small and focused not only improves the efficiency of the review process but also helps in maintaining a clean and organized codebase.

Provide Clear and Concise Descriptions

When creating a merge request, it is important to provide a clear and concise description of the changes you have made. This description should include any relevant information that reviewers might need to understand the purpose and impact of the changes. To make your description stand out, you can format important keywords in bold and use italics for subtle emphasis where needed.

If you have structured, quantitative data to present, consider using a Markdown table. Ensure that the table is succinct and formatted correctly in Markdown. On the other hand, if you have less structured content such as steps, qualitative points, or a series of related items, it is best to use a bulleted or numbered list.

Remember, the goal of the description is to provide enough context for reviewers to understand the changes without overwhelming them with unnecessary details. Keep it concise and to the point.

Tip: Avoid citing sources in your description and focus on providing clear and concise information.

Assign the Right Reviewers

Assigning the right reviewers to your merge request is crucial for ensuring the quality and accuracy of your code changes.
