Code review helps give a fresh set of eyes to identify bugs and simple coding errors before your product gets to the next step, making the process for getting the software to the customer more efficient. Simply reviewing someone’s code and identifying errors is great.

What should we do in code review?

Good code reviews look at the change itself and how it fits into the codebase. They will look through the clarity of the title and description and “why” of the change. They cover the correctness of the code, test coverage, functionality changes, and confirm that they follow the coding guides and best practices.

How can code reviews be efficient?

Why is it important to do a code review?

Code review is the most commonly used procedure for validating the design and implementation of features. It helps developers to maintain consistency between design and implementation “styles” across many team members and between various projects on which the company is working.

What are the two types of code review?

The first is known as peer review and the second is external review. The code review process doesn’t begin working instantaneously (especially with external review), and our process is far from being perfect — although we have done some serious research around the topic [3]. So, we are always open to suggestions for improvement.

How many lines of code should be reviewed at one time?

Don’t try to review the whole project at once. Experts advise not to review more than 400 lines of code at once. Moreover, a single check should take no more than an hour. The reason is humans cannot effectively process that amount of information, especially over such a long period of time.

What is the purpose of peer code review?

What is Code Review? Code Review, or Peer Code Review, is the act of consciously and systematically convening with one’s fellow programmers to check each other’s code for mistakes, and has been repeatedly shown to accelerate and streamline the process of software development like few other practices can.
