What is Peer Code Review Software?

Peer code review software facilitates a collaborative feedback and quality assurance process during software development. This software provides an organized means by which code can be examined, adjusted, and commented on by a developer other than the code’s author.

The code review process allows multiple developers to see changes to the code made by other developers, reducing the risk of bugs, security vulnerabilities, and missed requirements. Peer code review software also allows teams to check code for clarity and readability, which is an important aspect of programming. In a sense, the peer code review process facilitated by these tools is akin to the peer review processes used for writing projects. The fundamental value of these tools lies in the overall reduced possibility of human errors. However, these tools are also useful for onboarding newly hired developers. Developers with more experience on the team can review and comment on new developers’ code to instill team-specific best practices that aren’t necessarily universal. Even fully functional code can be improved by peer code review software. Team members can offer each other suggestions that result in better code, even if the original code is usable. Code review tools are used by software development teams in a project's development phase, which is cheaper, faster, easier, and more thorough than doing reviews during the requirements phase, testing phase, or after project delivery. By catching problematic code early, teams reduce the possibility of having to redo excess amounts of work.

Peer code review software allows developers to view not only code but also the specifics of what code was changed and to comment on those changes. These code review tools often integrate directly into other tools, including version control hosting solutions. This integration enables teams to smoothly incorporate the peer code review process into their standardized software development process.

What are the Common Features of Peer Code Review Software?

The following are some core features within peer code review software that can help users facilitate a smooth and effective code review process:

Commenting: Code commenting is perhaps the most fundamental feature of peer code review software, as it allows developers other than a code’s author to provide feedback asynchronously. Developers reviewing someone else’s code can highlight relevant parts of the code to leave comments on. If multiple developers are reviewing the code in question, peer code review software allows them to group or chain comments from different developers pertaining to the same lines of code. Then, the code’s author can hover over the highlighted code to view those comments and adjust as necessary.

Notifications: Peer code review software uses notifications to alert relevant users as the code review process progresses. When the code’s author determines that their work is ready for review, the code review tool will notify their peer review partner or partners. Then, when the peer review is complete, the software will notify the original author so that they can adjust their code against the completed peer review. Teams can also set the granularity for these notifications. If desired, the code’s author can be alerted to each individual comment or change made by a peer reviewer.

Prioritization: Most peer code review software allows reviewers to mark the severity of their comments. For example, if a peer reviewer finds an app-breaking error in the author’s code, they can both leave a comment and mark it as urgent or severe. This is usually accomplished via color coding or iconography such as an exclamation mark, drawing the author’s attention to the most important suggestions and corrections. Prioritization allows developers to delineate between minor preference differences and major flaws.

Standardized best practices: Most peer code review software allow teams to set and edit standardized best practices and metrics, which will be displayed prominently as a reference for peer reviewers to follow. Some peer code review software even automatically detect code that appears flawed and flags it for review, along with a description of the probable error. By making a team’s best practices and metrics more visible throughout the peer code review process, peer code review software reduces the possibility of human error and overlooked issues.

What are the Benefits of Peer Code Review Software?

The benefits of peer code review software are as mentioned below:

Quality assurance: Coding, like writing, produces complex and unique work depending on the author. While automated testing tools are important and useful in the software development process, a thorough and efficient peer code review process is vital to assuring code quality. Peer code review software helps team members evaluate each other’s work personally, which helps teams adhere to best practices and catch potential issues early. By validating code against other software developers’ judgment, code authors can better ensure their code’s readability and quality.

Collaboration: A peer code review process without the assistance of peer code review software is possible but tedious. Peer code review software facilitates easy and effective collaboration by structuring the peer code review process and notifying relevant users as the process progresses. Some peer code review software also help facilitate remote pair programming. Pair programming typically refers to a software development method involving two developers working on the same task together, with one programmer writing the code while the other makes comments and suggestions. With peer code review software, teams can engage with pair programming remotely by allowing disparate teammates to code and leave comments in real time.

Efficiency: In the software development world, it’s always better for issues to be caught early. When an issue goes unrecognized until the later stages of application development, it can result in a large amount of work needing to be redone. For example, if several elements of an application’s programming rely on the same foundational piece of code, and that code turns out to be flawed, then each of those elements is also flawed and may need to be reworked. Peer code review software helps ensure that problems are either addressed early or avoided entirely, which speeds up the development process and reduces headaches.

Who Uses Peer Code Review Software?

The following personnel can make use of peer code review software:

Senior developers: Peer code review software allows senior developers to review junior developers’ work. This facilitates knowledge sharing and mentorship within the team while also ensuring quality by getting experienced developers’ eyes on the code.

Junior developers: Developers of all skill levels use peer code review software, and those developers with less experience benefit from the practice of reviewing their peers’ code. This enables them to better understand their team’s best practices and share the knowledge.

Managers: Managers on software development teams sometimes review code changes using peer code review software, though it tends to happen at an infrequent cadence. This ensures that managers are keeping an eye on their team’s code quality and offering mentorship where applicable.

Software Related to Peer Code Review Software

Related solutions that can be used together with peer code review software include:

Secure code review software: Secure code review software enables either automated or manual code examination to seek out vulnerabilities and security risks. These solutions are similar to peer code review software, but they are specifically focused on ensuring security best practices as opposed to general coding best practices, and some solutions execute automated code remediation rather than enabling peer review.

Software testing tools: Software testing software gives development teams the methods and tools to determine the quality of their software creation and improvement projects. Development teams use software testing tools to assess whether the software is usable, performs properly, meets development team goals, and meets overall requirements.

Automation testing software: Test automation software controls the execution of software tests. It simplifies the testing process for software engineers by using the minimum set of scripts, saving their teams time and money. These tools, typically utilized by large enterprises, allow teams to run pre-scripted tests on their applications before they are pushed into production.

Bug tracking software: Bug tracking software, or issue tracking software, refers to software used by quality assurance (QA) and software development teams to report software bugs and problems. Bug tracking software provides a repository that explains how to reproduce a bug and how widespread an issue is, allowing a business to separate, prioritize, sequence, and provide communications about different bugs across many projects or applications.

Challenges with Peer Code Review Software

Software solutions can come with their own set of challenges.

Effective notifications: Companies should ensure that the peer code review software they’re interested in buying meets their requirements for effective notification. If the routes and methods that a peer code review tool uses to notify users of new comments don’t do enough to alert team members effectively, the entire process is slowed down. Notifications need to be clear, and developers should be able to click them once to jump right into the relevant section of the codebase.

Standardized peer review: Standardizing the peer code review process helps companies ensure consistent code quality. With that in mind, companies should look for peer code review software that helps them standardize the process. An ideal solution should make best practices clear and remind users of important metrics so that each review is thorough and productive.

Which Companies Should Buy Peer Code Review Software?

Any company with a software development team should use peer code review software, as it is a fundamental part of quality assurance and team collaboration.
