Software developers work hard to deliver quality software. The quality of software Code is critical to ensure high-performing software. Code reviews help in detecting flaws in code and thus rectify them to reduce any chances of bugs.

Code reviews include a set of activities performed by developers, reviewers, and QA managers to check the quality of code as per coding standards. Code review is done to check the potential flaws, consistency issues in the code, the quality of comments.

Code review is a productive way to achieve and identify security vulnerabilities in the software. It can also be automated using tools. Automated code reviewing also checks the errors in software code for memory leakages, size violations, duplicity, buffer overflows, and race conditions. It is commonly performed in agile methodology.

Code review helps in finding mistakes, catches bugs early and ensures that code is created as per industry standards. This technique improves two-way communication where both coder and reviewer learn from each other experience and remove potential mistakes which could impact the product later.

Code review is a great way that significantly removes the bugs which have the potential to hamper application output and results. Early to find bugs have a great advantage in software quality and cost. Bugs found after release cycle turns out to be more expensive and time-consuming. This problem has given rise to a new testing technique which is the Shift-Left Testing technique which starts right at the requirement gathering stage. Testers often use issue tracking tool to log and monitor issues in the software application. Each issue is linked to specific requirements and test cases that will be fixed by developers.

Here is the list of benefits of code reviewing:

There are two types of code reviews based on the size of your application:

Formal code review where developers collaborate with various participants and work on the code. This process is conventional and effective in finding defects.

Lightweight code review: This process is also useful and uses less effort for code review. It is done in parallel to development. It is done in four different ways:

The code review technique is an excellent method to save time, effort, and cost involved in finding bugs. This method not only releases high-performing software, but it also streamlines other processes of the entire software development life cycle. It offers tremendous learning and experience of a team which further improves their skill set.
