Pull Requests

A distributed version control workflow that lets developers propose, review, and merge code changes into a central repository.

Pull requests (PRs) function as the primary mechanism for collaborative software development within Git-based platforms like GitHub, GitLab, and Bitbucket. When a developer completes a task on a feature branch, they initiate a PR to notify team members of the proposed changes. This creates a dedicated forum for code review where peers leave inline comments, run automated CI/CD tests (like Jenkins or GitHub Actions), and request specific revisions. Once the code meets the project's quality standards and passes all status checks, a maintainer merges the branch into the main codebase, ensuring that every addition is vetted before deployment.
