What Is PR (Pull Request) in Software Development

Benefits of using pull requests in software development

Pull requests have become an integral part of the software development workflow, offering numerous benefits for both individual developers and development teams. These benefits include:

Code Quality: Pull requests provide an opportunity for peer review, allowing other developers to review the code changes before they are merged into the main codebase. This improves the overall quality of the code by catching bugs, identifying potential issues, and suggesting improvements.
Collaboration: Pull requests foster collaboration among team members. Developers can communicate and discuss the changes within the context of the pull request, leading to better solutions and knowledge sharing.
Transparency: Pull requests offer transparency in the development process. They provide a detailed record of all changes made, discussions had, and decisions made during the review process. This helps in tracking the evolution of the codebase over time.
Knowledge Transfer: Pull requests serve as a valuable learning tool, especially for junior developers. By reviewing and discussing other developers’ code changes, they gain insights into different coding styles, best practices, and problem-solving techniques.
Quality Assurance: With pull requests, developers can run automated tests on the code changes before merging them. This ensures that the changes do not introduce new bugs or regressions into the codebase.
Maintainability: Pull requests make it easier to maintain and update the codebase. By reviewing and discussing changes before merging, developers can catch and address potential issues early on, preventing future technical debt.
Flexibility: Pull requests provide the flexibility to experiment with new ideas or features without impacting the main codebase. By creating a branch and submitting a pull request, developers can gather feedback and iterate on their changes before merging.

These benefits highlight the significant role that pull requests play in improving code quality, fostering collaboration, and maintaining a robust and efficient software development process. By leveraging pull requests, development teams can ensure that their codebase benefits from collective knowledge, scrutiny, and quality assurance.

How pull requests work

Pull requests are a fundamental component of a collaborative software development process. They enable developers to propose changes to a codebase, review the changes, and then merge them into the main codebase. Here’s an overview of how pull requests work:

Creating a Branch: Developers start by creating a new branch in the repository. This branch serves as a container for the changes that will be proposed in the pull request. Creating a branch allows developers to work independently without affecting the main codebase.
Making Code Changes: Once the branch is created, developers can start making code changes specific to the task at hand. This could involve adding new features, fixing bugs, or improving existing code. Developers typically make commits to the branch as they progress.
Opening a Pull Request: When developers are ready to share their changes with the team, they open a pull request. This notifies the team that changes have been made and need to be reviewed. In the pull request, developers provide a description of the changes made, their purpose, and any context that may be helpful for reviewers.
Reviewing the Changes: Team members, including other developers and project managers, review the pull request. They examine the changes, comment on specific lines of code, suggest improvements, and raise any concerns or questions they may have. The review process encourages collaboration and ensures the quality of the proposed changes.
Addressing Feedback and Discussions: Based on the feedback received during the review process, the developer who opened the pull request can make additional commits to address the feedback. Discussions continue until reviewers are satisfied with the proposed changes.
Merging the Pull Request: Once the changes have been approved, they can be merged into the main codebase. This integrates the proposed changes with the existing code, making them a part of the project. Merging involves resolving any conflicts that may arise between the proposed changes and the existing codebase.
Closing the Pull Request: After the pull request is merged, it is closed, signaling that the proposed changes have been successfully incorporated into the project. The branch used for the pull request can be deleted, as it has fulfilled its purpose.

This process of creating branches, making changes, opening pull requests, reviewing and addressing feedback, and ultimately merging the changes allows for a systematic and collaborative approach to software development.

Difference between pull requests and traditional code reviews

In the traditional code review process, developers would make changes directly to the main codebase, and then request a review from their colleagues. Pull requests, on the other hand, have revolutionized the code review process and introduced several key differences. Here are the main distinctions between pull requests and traditional code reviews:

Isolation: Pull requests allow developers to make changes in isolated branches, separate from the main codebase. This isolation ensures that the codebase remains stable while changes are being reviewed. In contrast, traditional code reviews involve making changes directly to the main codebase, which can pose risks if the changes are not thoroughly reviewed and tested.
Collaboration: Pull requests promote collaboration among team members. They provide a centralized platform for discussions, comments, and suggestions within the context of the proposed changes. This enables developers to provide detailed feedback and engage in meaningful conversations. Traditional code reviews often rely on tools like email or chat platforms, which may not offer the same level of collaboration or context.
Visibility: Pull requests offer transparency and visibility into the code review process. They provide a detailed history of the changes made, including all comments and discussions. This allows team members to track the progress of the review and understand the rationale behind each decision. In contrast, traditional code reviews may lack this level of visibility, as comments and decisions can be spread across various communication channels.
Automation and Integrations: Pull requests can be integrated with various automated tools and workflows. Continuous integration systems can automatically run tests on the proposed changes, ensuring that they do not introduce any issues. Additionally, code analysis tools can provide insights and suggestions for code improvements. Traditional code reviews often rely solely on manual review processes, which may be time-consuming and prone to human error.
Reviewer Roles: Pull requests allow for more structured and defined roles for reviewers. Different team members can be assigned as reviewers, ensuring that changes are reviewed by individuals with relevant expertise. Traditional code reviews may lack this explicit assignment of reviewers, leading to potential biases or inconsistencies in the review process.

These differences highlight the advantages that pull requests bring to the code review process. They enhance collaboration, improve code quality, and streamline the overall development workflow, making them a preferred choice for many software development teams.
