Code review is an essential part of the development process. It lets you identify problems with your code before it is implemented and helps reduce the time spent on fixing bugs.
In this blog, we’ll explain what the code review process is and what tools you can use to automate it.
What is the code review process?
Code review is an important process of orderly testing of software to find and remove errors, bugs, overflows, and other vulnerabilities found in the code. A good code review process is constructive, limited, and instructive.
It is important to review code because:
- Improves code readability
- Improves code quality
- Creates better documentation
- Optimizes code for better performance
- Knowledge sharing
This process directly impacts the review time. For example, If reviewers are overloaded with work, they make take time to review the respective code. As a result, the review time will increase which further results in high cycle time.
Why code review tools are important?
- Code review tools automate and streamline the review process. Hence, making it more efficient and decreasing the review time.
- These tools can help in providing a clear structure for the review and ensure code quality and consistency.
- Code review tools help in getting a clear audit trail of the review process. For example, Who reviewed the code, when it was reviewed, and feedback provided.
- These tools facilitate knowledge-sharing and collaboration.
Now, let’s take a look at some of the most popular code review tools:
