In recent times, the importance of code review has been acknowledged for developing top-performing software. It is one of the best methods for preventing security flaws & defects from getting into production.

True to this aspect, the demand for effective code review tools has also shown an upward trend. In this post, we have listed some of the best code review tools for developers.

What Is the Code Review Process?

A code review process is a methodical approach to identifying potential security flaws and bugs in software code. It involves careful examination of the source code by one or more individuals with expertise in programming and software development.

Why Is Code Review Important?

There are several reasons why code review is essential for developers:

  • Ensures quality of the codebase and prevents security flaws and defects at an early stage.
  • Helps identify errors, potential vulnerabilities, and areas for improvement in the program.
  • Makes sure that the code follows the best industry practices and coding standards.
  • Helps in identifying and removing unnecessary deficiencies 
  • Aids in mentoring new programmers
  • Helps build a knowledge base of common mistakes and loopholes.

How to Perform a Code Review?

There are various ways to review a code. Here is the summary of three major ways of code review:

  • Peer Review: In this method, the code is reviewed by another developer who has expertise in the same programming language. The reviewer will go through the code line by line and identify any clerical or logical errors, potential vulnerabilities, or areas for improvement.
  • Static Analysis: In this approach, special tools are used to analyze the source code for errors, without running the code. static analysis tools can be used to automate some of the tasks involved in code review, such as checking for compliance with coding standards.
  • Dynamic Analysis: This method involves running the program and testing it against known inputs and outputs to see if there are any defects or errors. Dynamic analysis can be used to find flaws that cannot be detected by static analysis alone. Its more than just review and can be termed as a part of STLC (Software Testing Life Cycle).

A code review tool is a software application that helps developers to streamline, integrate and automate the code review process. It includes a set of static analysis tools that can be used to automate the tasks involved in code review, such as checking for compliance with coding standards.

Why Should You Use Code Review Tools?

There are multiple advantages of using code review tools:

  • Streamline the code review process by automating the tasks involved
  • Makes it easier to integrate code review into the software development process
  • Provides a way for developers to collaborate on code reviews
  • Brings transparency and consistency to the entire code reviewing process
