The tone of your code review will impact the morale of the developer team. If you carry out a review with a harsh tone, you might end up creating a hostile environment with problems like microaggression and lack of trust. The overly opinionated language will make people defensive and might spark heated discussions that aren’t really productive. For best results, review no more than 400 lines of code at a time.

It’s as if people from the future or another world had read about movies but had never seen one. They understood that there’s a script and that you film people saying things and pretending it’s real. The result illustrates the difference between doing something you’ve read about and doing something you’ve seen. Readable code is great, but not all code will be immediately readable.

Why is it a good idea to review code?

So, what exactly is a good code review and how to achieve the idea? Read this article to learn the ins and outs of code review best practices from our team at Codete. That’s all good and well, you might say, but how do I actually go about doing a code review, and make sure I do it properly? Before reviewing the author’s code, make sure you’ve identified the purpose of the session, and be sure to follow these best practices. While it may be tempting to never want to show anyone your code out of a sense of embarrassment, a code review helps both the reviewer and the reviewee learn.

Verify that API endpoints perform appropriate authorization and authentication consistent with the rest of the code base. Check for other common weaknesses, e.g., weak configuration, malicious user input, missing log events, etc. When in doubt, refer the CR to an application security expert.

Build a process for requesting and approving changes

Sometimes you might need to prepare a formal report of your findings and then submit that as a Word document or PDF. Imagine you have a co-worker or friend who’s asked you to review a piece of code for them. You might be thinking, “Wait, I don’t really know what that means.” Maybe you’re too nervous to say that to your colleague. Make sure pull requests are minimal and serve a single function. Many people have never seen a good code review, a better code review, or any code review.

When you approach reviews as a learning process, everyone wins. Giving yourself time to do short, frequent reviews will help you improve the quality of the codebase. Performance and attention-to-detail tend to drop off after that point.

The peer review process also benefits from holding team members accountable. This means conducting follow-up investigations to verify that there are no defects within the code prior to moving into production. In addition, code review promotes the flexibility to build new features instead of spending time analyzing existing code. This means that there is scope for innovation within the software development process. As your code base grows and the many contributions from different team members come together, stylistic differences can take a toll on productivity. This issue can balloon into a show-stopping problem that effectively cripples development momentum and needlessly frustrates your team.

  • Also, I guess, it is a good practice for developers to annotate source code before the review.
  • Providing feedback can be harmful and unpleasant if you don’t execute the review process properly.
  • However, aSmartBear studyindicates a considerable decline in defect density at speeds quicker than 500 LOC per hour.
  • By using external and internal metrics, you can decide whether the code review needs revising or it’s going in the right direction.

The fundamental purpose of a code review process, as described earlier in this article, is to enhance efficiency. While the traditional code review approaches outlined above have worked in the past , you may be losing efficiency if you haven’t switched to using a code review tool. A code review tool automates the code review process, freeing up the reviewer’s time to concentrate solely on the code. Your ultimate guide to Heroku custom domain name Code review is vital, but it can also be a time-consuming as well as a painstaking process. As a result, it is critical to control how much time a reviewer or team spends on the specifics of each line of code. Every member of your team is quite likely to repeat the same mistakes because omissions are the most difficult to identify since it is hard to evaluate something that does not exist.

One helpful suggestion for avoiding inserting personal preferences in a review is to ask the author if you can meet at a separate time for a knowledge share. This way, teammates can have healthy, conversational debates and share knowledge and best practices without stalling the current codebase. Along the same lines, industry experts recommend being mindful of how much time you spend conducting a code review to yield the best results. Software developer Kathryn Hodge recommends spending no more than 60 to 90 minutes completing a code review. This falls in line with productivity research that suggests the most productive people work for approximately 52 minutes at a time, then take a break for 17 minutes.

Decentralized knowledge can foster colleagues' trust rather than a “mine vs. yours” ownership mentality. Good code reviews are the bar that all of us should strive for.

In other words, senior developers shouldn’t be the only ones reviewing code. Entry-level developers can provide a fresh perspective and should be integrated into the process from the start. To improve your code reviews, take the attitude that you can learn something new from everyone on your team.

Use code owners to ensure that the right developers have reviewed the code as merge checks. While it’s helpful to identify problems within the source code, it’s more beneficial to explain why specifically they’re a problem. You want to be constructive and instructive with your feedback.
