Why are Code reviews important? Code reviews are crucial in the industry because they give the opportunity to review the current state of code in a project before it is put into production. When done properly, this prevents critical bugs, regressions and vulnerabilities in production systems.
The ability to perform code reviews is one of the skills that every professional software engineer should have to a certain degree. Given that it takes time, effort and some expertise on your part, you’re going to want some help from others as well who can walk you through what you’re doing wrong and provide other ways of doing things better.
Regardless of whether it’s just for yourself or with an individual peer or at a team project level code review, these services could help tremendously when performing these types of checks.
Another look: Why are Code reviews important?
A review can be done periodically to check the quality of the code. It’s much easier to fix bad code before it gets checked into a source control repository. Many companies do this by having a code review at the end of every development phase or before every PR merge, such as weekly or on each iteration of an Agile project. Some people like to maintain high code quality and will perform many reviews while they are coding new features or even bug fixes and throughout the life cycle of their software product.
Every change should be reviewed at least once, even if that means sending it to oneself for a double-check to make sure nothing slipped through the cracks.
Common concerns and issues with code reviews.
Code reviews can be seen as a disruptive process for the team. For example, it might interrupt the development process, distract people from what they should be working on, and slow down progress. It’s important to work out and communicate a plan with your team members so that they’re not surprised or taken by surprise when you decide to bring code reviews into your process.
Privacy concerns are also a concern in code review tools. Software engineers often have private work profiles in order to keep their identities secret, and many companies allow private code review tools as a means of keeping those identities secret. This is an issue because it only works if the company itself does not make releases or parts of the source code public. Furthermore, these private review tools can be used to spread software viruses, since malicious authors are more likely to do that in order for more people to gain access to their reviews and critique the code.
A code review may increase the number of errors produced in a project since bad programming is more likely to be caught. Bad code will end up being heavily criticized, increasing the risk that programmers will become upset or feel that they are being targeted unfairly.
Overall, code review is an extremely valuable tool in order for us to produce better quality software products. There are many types of reviews including peer reviews, automated static analysis and certification programs for both open source and proprietary software.
Generally speaking, a reviewer should be able to find one or more things that can be improved on; this usually occurs within three minutes of reading the code.
A review should try to identify where requirements are not met but are not explicitly written in their requirements document; this leads to a lack of clarity which can cause confusion when requirements are changed over time.
A good technique to learn from other people’s good practices/bad practices is through reading/reviewing technical articles, presenting at conferences or competitions, writing books and articles. These sources of information are widely available online and in print formats.
