Software development includes many processes and code review is one of them. It involves the testing of source code to identify bugs at an early stage. Code review process is generally conducted before emerging with the codebase. A successful code review prevents bugs and errors from getting into your project by improving code quality at a beginning phase of the software development process. Code review tools automates the review process which reduces the reviewing task of code. There are two ways to perform review- Formal inspection and Walkthroughs. Using formal inspections, we can find out more defects but it is time consuming and difficult.
Here we’ll see the details of code review and most popular code review tools.
What Is The Code Review Process?
Main goal of code review process is to analyze new code for bugs, errors and quality standards set by the organization. Code review processes should not only consist of one-sided feedback. So, the benefit of code review process is the team’s improved coding skills. If you’re thinking to initiate a code review process in your organization, you should first decide who would review the code. If you have a small team, you may assign team leads to review all code. And if a team is larger in size with multiple reviewers, you can enable a process in which each code review is assigned to skilled developers. You have to decide on timelines, rounds and minimal requirements for submitting code review requests. Last consideration is about how feedback should be given in the code review process. Ensure that you highlight the positive aspects of code while suggesting alternatives of drawbacks. Let us see best code review tools in market.
