Code review is an integral part of the development process. It is used to find out bugs and errors at an early stage of development itself.
The code review tools are so designed that it automates the whole process of reviewing the application development process. Thus, it has become an important tool for the development team.
This code review process helps improve the quality of the software. To help you out, we have listed out the top eight free and open-source code review tools that you might want to take a look at.
The code review process is orderly testing of software to find and remove errors, bugs, buffer overflows, and other vulnerabilities found in the codes.
These code review processes are methodically documented and follow severe defect detection techniques from peers and technical experts. There are basically four, sometimes five participants who are involved in code creation and code inspection the author, the moderator, the reviewer, the reader, and sometimes an observant.
The code reviews are led by trained moderators and reviewers who are NOT the author of the coded program, and these reviews are performed without any management participation.
Since it is a quality assurance activity, reviewers scrutinize the codes written by the authors and prepare a report with a list of findings to be fixed.
There are many processes and techniques to perform a code review which usually involves a lot of meetings between the distinct roles mentioned above.
There are heavyweight inspection processes that go up to 6-7 steps involving everyone to work only when the code review comes on their plate and there are lightweight inspection processes that involve everyone to work simultaneously with each other.
Not many follow heavyweight inspection processes anymore, which means lightweight processes are trending more with the increase in the development of software applications across the globe.
Here are a few lightweight inspection techniques:
This code review process is the most informal and common. Over-the-shoulder means that a reviewer hovers over the author while the author displays the changes made in the code at their coding workstation.
The author is the person that leads the code review by sitting at their computer, explaining the changes he/she made in the code while going through multiple tools and files in the project.
If the reviewer finds any discrepancy, then they engage on the spot with the author (this engagement is called pair-programming) to fix the missed issues. If the changes are too significant, then the entire live code is taken off-line.
However, with modern desktop-sharing tools, this over-the-shoulder review has become remote and easy to implement over long distances.
This process of code review is prevalent and preferred by most open-source projects. Here, the entire file or changes in the code are packed up by the author and sent to the reviewers through email. Reviewers then examine the code data, ask relevant doubts and queries in the same thread to the authors.
In this method, it is easier to involve other developers through the email itself to ask for suggestions, changes in the code, expert advice, or even complete deferral.
People generally associate this technique of code review with Extreme Programming (XP) because it incorporates a continuous code analysis. In pair-programming, two developers produce code from a single workstation, with only one authoring the code and the other person freely discussing any changes and suggestions needed as a reviewing developer.
Pair-programming has shown to be very useful in finding bugs as well as promoting knowledge transfer.
However, this process poses a controversial issue about whether it is better or worse or equivalent to more standard reviewing methods because the reviewing developer is continually being a critique polishing the code.
At the same time, the author might get frustrated and keep losing his/her chain of programming the code every time in between writing and listening for suggestions.
A code review done with the help of specialized tools that helps in processes like collecting files, commentary, transfer, and displaying data, collecting metrics, etc., is called a tool-assisted review.
Tool-assisted reviews can allow product managers and administrators to exercise some control over the workflow. Such type of review process is mostly preferred in commercial software, open-source projects, or home-grown scripts.
Either way, it requires a lot of money to be invested in specialized tools to create a better code review environment.
These code review processes help improve the quality of the software. To help you out, we have listed out the top eight free and open-source code review tools that you might want to take a look at.
