Top 10 Most Popular Code Review Tools for Developers and Testers

Introduction to Code Review:

Code Review is nothing but testing the Source Code. Generally, it is used to find out the bugs at early stages of the development of software.

With this code review, the quality of the software gets improved and the bugs/errors in the program code decrease.

Code Review Tools

The Code Review Tools automates the review process which in turn minimizes the reviewing task of the code. There are two ways of performing reviews namely Formal Inspections and Walkthroughs.

However, these both techniques are heavy-weight techniques that may not be practical sometimes. Using formal inspections we can find more defects but its time consuming and difficult.

Few other light-weight techniques have been explored. They are mentioned below

  1. Over–the–shoulder: The developer stands behind the author’s shoulder who reviews the code. This is an informal review.
  2. Email pass around: The author sends an email of the code to the reviewers for code review. This technique is preferred by open source projects.
  3. Pair Programming: Two developers develop the code together on a single machine. This is a time-consuming technique.
  4. Tool-assisted: Few specialized tools are used by authors and reviewer to review the code.

Note: Code Reviews are documented as the efficient way of finding the errors in a code and fixing the same at early stages.
