--Code review is one of the primary means of assuring the quality of released software along with testing and static analysis. However, code review requires experienced developers who may not always have the time to perform an in-depth review of code. Thus, automating code review can help alleviate the cognitive burden on experienced software developers allowing them to focus on their primary activities of writing code to add new features and fix bugs. In this paper, we describe our experience in using Large Language Models towards automating the code review process in Ericsson. We describe the development of a lightweight tool using LLMs and static program analysis. We then describe our preliminary experiments with experienced developers in evaluating our code review tool and the encouraging results. There are multiple orthogonal and mutually complementary techniques to ensure the quality of the software. Typically, these methods include software testing that dynamically executes the software under test to detect bugs; static program analysis that analyzes code without running it to discover problems such as a potential division by zero; and code reviews which involve experienced developers reading the code to find issues in the software.

Code review is a part of the software development process which involves testing the source code to identify bugs at an early stage. A code review process is typically conducted before merging with the codebase. An effective code review prevents bugs and errors from getting into your project by improving code quality at an early stage of the software development process. In this post, we'll explain what code review is and explore popular code review tools that help organizations with the code review process. The primary goal of the code review process is to assess any new code for bugs, errors, and quality standards set by the organization. The code review process should not just consist of one-sided feedback. Therefore, an intangible benefit of the code review process is the collective team's improved coding skills. If you would like to initiate a code review process in your organization, you should first decide who would review the code. If you belong to a small team, you may assign team leads to review all code.
