A SmartBear study of a Cisco Systems programming team revealed that developers should review no more than 200 to 400 lines of code (LOC) at a time. Many facets of a code review, however, are not straightforward. 2. This allows each person to focus on their area of expertise (in the case of refine your code before sending it out for review. This brings us back to the guidelines we developed to govern the subjective elements of the NRDB team’s code review process. 1. Clearly define the responsibilities of each reviewer. Instead, split them into smaller interfaces based on the functionality. 1. For the first few weeks it was hard to break old habits, and we had to remind several team members to add the blocking and non-blocking tags during their pull request reviews. The computer science curriculum focused on algorithm analysis, data modeling, and problem solving. In too many cases, we weren’t handling subjective feedback in a constructive manner—in fact, just the opposite was true. in the code review to reference later and provide context to other reviewers. We have also reduced the time required to onboard new new team members and to get them up to speed with our code review process. Never ship code until you have reviewed all of it. Code review can have an important function of teaching developers something newabout a language, a framework, or general software design principles. Make sure your code is easy for reviewers to follow, Make any relevant documentation easily available for reviewers, Confirm that your reviewers are aware of any major changes (if any) you a) Maintainability (Supportability) – The application should require the … Code review guidelines 1. Please join us exclusively at the Explorer’s Hub (discuss.newrelic.com) for questions and support related to this blog post. 2. Make sure to summarize the change you’re making, why you are making those Code Review Guidelines We deeply value code review and feel that it’s crucial to being a high-functioning engineering organization. It’s fine to conduct a “drafting” review to solicit preliminary feedback, but changes, and link to a ticket or spec to provide any additional context. Give your reviewers context on your change. The OWASP Code Review guide was originally born from the OWASP Testing Guide. Don’t ship code without approval from your primary reviewer unless you are As a result, we decided that “The author of the code change is responsible for the correct execution of the change.”. We decided as a team to take a step back; we resolved to figure out what was going on, why it was happening, and what we could do to fix it. 3. As we choices. You should actually pull down the code and … Those pull requests need to be reviewed by someone. Being able to differentiate clearly between these two types of feedback can be critical to the success of a code review, and to the effectiveness of a development team. It covers security, performance, and clean code practices. code meets these standards, ask a teammate to help complete the code review. When reviewing code, you should make sure that it is correct. This is where the rigid emphasis on code review as a totally objective activity, and the failure to consider the creative nature of software development, can become a problem. Is the code as general as it needs to be, without being more general the lookout if the code is changing the serialization / deserialization They didn’t explicitly reject it, but they didn’t approve it either. In this case, understanding code means being able to easily see the code’s inputs and outputs, what each line of code is doing, and how it fits into the bigger picture. That said, as a reviewer, you should not give the code a “ship it” if The views expressed on this blog are those of the author and do not necessarily reflect the views of New Relic. Our four guidelines for code reviews. Privacy: Don’t publicize people’s private information. Code Review Guidelines. Keep your code reviews small so that you can iterate more quickly and Search the blog, Monitor New Relic from your phone or tablet. explicitly have a primary reviewer listed so that everyone knows who has final We found that subjective comments were most often presented as objective feedback at the pull request stage of the process. This demonstrates why asking for changes, rather than demanding them, builds stronger teams: the author feels less resentful, and the reviewer feels that the author genuinely appreciated their feedback. Do not create lengthy interfaces. Be kind. This document is a guide that explains our expectations around PRs for both authors and reviewers. Isthe way the code behaves good for its users? Non Functional requirements. Before you check in your code, you can use Visual Studio to ask someone else from your team to review it. sure to communicate this to the reviewer as early in the process as possible. Whether you are reviewing code or having your code reviewed, communication is momentum. Never give a “ship it” if you’re not confident the code meets these standards. Code review is often overlooked as an ongoing practice during the development phase, but countless studies show it's the most effective quality assurance strategy. We’ve identified a few other terrific benefits from this process. dependencies. This was a highly skilled and very passionate group of developers reviewing one another’s pull requests. If you need to make major changes after submitting a review, you may Consider urgency and estimate if the feature your colleague is working on is urgent or not. Identifies common errors and shares them with your team, reducing rework and promoting understanding of the codebase across teams. It’s impossible for us to lay out guidelines which will be applicable to every situation so staying mindful of these goals will help you adhere to “the spirit” of code reviews even when you encounter a … Code Review is an integral process of software development that helps identify bugs and defects before the testing phase. Reviewers may mix their subjective and objective comments without acknowledging the differences; here too, the process can end in resentment, frustration, and a breakdown in team communication. As a result, the bugs that survive are much harder to find, especially when you’re at the end of the process and are just looking at a code snippet with limited context. As a submitter, remember that reviewers have their own tasks, deadlines, and improvements to implement. As a result, the NRDB team’s developers grew increasingly frustrated, team trust eroded, and several members (myself included) contemplated switching to other teams. Functionality: Does the code behave as the author likely intended? And when we dislike and disagree with what we find in such cases, we often forget that these “flaws” are subjective matters of opinion—not objective matters of fact. Hence, code review is a process and not a technology. conversation (e.g: offline or in chat). the code’s for correctness rather than style. Communication is key to prevent yourself from getting blocked on code reviews. code is bug-free, solves the intended problem and handles any edge cases “drafting” state or open a new code review. If you find yourself having long Generally speaking, all code in a codebase should be tested. process. You should always There is some Google-internal terminology used in some of these documents, which we clarify here for external readers: For larger-scale code reviews, expectations should be It takes two to tango, so at least one developer has to be involved except the code author, but of course, more developers can – … the code style changes as a branch and then follow-up with a branch to change responsible for the final code as the person who wrote it.

To help keep your code reviews small, keep code reviews that change logic Many developers are trained from the start to downplay differences between the two types of feedback. Use I-messages: 1.1. You are responsible for making sure that the code is correct, with, Make sure you completely understand the code, Check for well-organized and efficient core logic. First, as a preliminary to our four guidelines, we agreed to define who is ultimately responsible for the correct execution of any code changes. Sharingknowledge is part of improving the code health of a system over time. As the name implies, the NRDB team is responsible for the development of our events database, which powers the New Relic Insights tool as well as several other products. separate from reviews that change code style. When reading through the code, it should be relatively easy for you to discern the role of specific functions, methods, or classes. We also noticed that when a reviewer did write a non-blocking comment asking for a change, the author typically made the requested change or came up with a compromise—even though the author had the option of ignoring the comment. The brain can only effectively process so much information at a time; beyond 400 LOC, the ability to find defects diminishes. to find more appropriate reviewers or determine a timeline that works for all This is obviously much more practical with smaller code review (see For everything else there is always the open Internet. This may seem obvious, but not all teams work that way. critical and both parties need to address that feedback is a suggestion that’s For example: As we adopted these guidelines, the team had the most difficulty with the fourth one.

Every two weeks, we hold a retrospective meeting where team members are welcome to suggest changes or additions to our coding standards. It’s useful to contrast this approach with the one employed in an academic creative writing program. This approach also makes it easy to forget that a debate over subjective issues during a code review can get emotional and heated very quickly. High-level comments For such concerns, we agreed that a reviewer could choose to sponsor an addition to the team’s coding standards. think about whether it should be in the guidelines.
