The quality of the code base is ensured by code reviews. To gain a second opinion on the issue and its implementation, software engineers should be encouraged to get their code examined as soon as they’ve finished coding.
In order to find bugs, logical errors, or undiscovered edge cases, the reviewer might also serve as a second step.
As long as they are a domain expert, reviewers can come from any team or organization. Two professionals should review the code if it has lines that cover multiple domains.
The foundation for continuous improvement is laid by establishing a robust code review procedure or by using version control to stop unstable code from reaching clients.
To make sure that every piece of code has been reviewed by another team member, code reviews should be incorporated into the workflow of software development teams.
The code review procedure plays a crucial role in transferring knowledge throughout a company and providing clients with high-quality products.
Increased efficiency is the primary result of a code review process. If you haven’t moved to a code review tool, even though these conventional techniques of code review have in the past been effective, you may be losing efficiency.
An automated code review tool allows a reviewer to concentrate completely on the code by automating the code review process.
Before new code is integrated into the main repository, a code review is launched using integration with your development cycle. To easily include a tool into your workflow, pick one that works with the other components of your technology stack.
Static and dynamic code testing are the two forms that are used in software development.
When performing a dynamic analysis, a specified script will often run unit tests and check to see if the code adheres to a set of rules.
Static code testing is carried out when a developer writes new code that will be incorporated into the existing code.
A list of tools that can be used in the code review process include Crucible, Gerrit, RhodeCode, Collaborator, Veracode, Reviewable, GitHub, Phrabricator, and many more.
Benefits of Code Review
Sharing information
Software developers can discover fresh approaches and fixes by reviewing the code as soon as a member of the team updates. Similar to how good pair programming encourages developers to exchange knowledge and ideas, code reviews assist junior developers learn from more experienced team members.
Identify bugs earlier
Developers have the advantage of promptly identifying and resolving issues before they reach customers, instead of discovering defects after a feature has been deployed and rushing to release a patch.
By including unit tests earlier in the software development lifecycle, developers can work on fixes while still learning new things.
Keep up compliance
Developers come from different educational and professional backgrounds, which affects how they code. Code reviews assist everyone in upholding the same standards if teams want to have a uniform coding style.
This is crucial for open-source projects where numerous developers contribute code. Before submitting modifications, maintainers review the code as part of peer reviews.
Boost security
Code reviews increase security, particularly when security experts conduct a focused evaluation. Software development must include application security, and code reviews help make sure compliance.
Members of the security team can scan code for flaws and warn developers of the danger.
Disadvantages of Code Review
Longer shipping time
Since reviewers and writers must work together to discuss issues, the review period may cause a delay in the publication process.
Reviewers might not finish a review as quickly as the author would want, depending on their workload. By using code review techniques that incorporate automated testing to discover mistakes, this problem can be solved.
Remove attention from other tasks
A code review might divert a developer’s attention from other high-priority activities that they are accountable for completing.
Developers frequently have a heavy workload. Team members might have to choose between finishing their assignment and stopping to do a code review. Work is delayed somewhere within the company in either scenario.
