Senior developers can guide juniors, while fresh perspectives from newer team members bring valuable insights. Dive into the Software Development Life Cycle (SDLC) and learn how it streamlines project success from conception to deployment. Step 11 − Once the code is merged to the production, it is checked if the new changes in the code are working fine and they have not impacted any part of the existing code.

Best practices for code reviews
It is essential for the author to consider not only the functionality of the code but also its scalability and maintainability. By anticipating potential future requirements and ensuring the code is flexible enough to accommodate them, the author can contribute to the long-term success of the project. Additionally, documenting any known limitations or trade-offs made during the development process can provide valuable insights for reviewers.
What are the disadvantages of code reviews?
The code author prepares the code for review and makes sure that it’s complete, well-documented, and complies with the organization’s coding standards. One or more code reviewers examine the code, suggest improvements, and point out any bugs, issues, or architectural flaws. The code author and code reviewers discuss the issues and once they’re resolved, the code is merged into the codebase. Obtaining a second opinion on the implementation can help identify any potential problems or areas of improvement and help developers understand the code better. Additionally, it can help to ensure that the code is of the highest quality and adheres to coding standards and best practices. Furthermore, it provides valuable feedback to developers on their code and helps to identify any areas that need further attention.
Best Practices for Effective Code Reviews
Step 8 − The author incorporates the changes and may have multiple discussions with the reviewers till all the issues are addressed and resolved in the code. Step 4 − The reviewers may follow checklists or guidelines while reviewing the code to maintain consistency. Step 1 − The developers complete the code and create a review request or inform the team about the same. A developer may be requested to have a quick look at the code and provide feedback not formally. It is a type of review in which the code changes sent over email for review. The developed code for a software needs to be reviewed in order to make it robust.
Establishing a Code Review Culture
But don’t write a complete solution to the problem when explaining why. Find a balance between reporting the problem and providing a straightforward solution. Always explain why the author needs to make changes and add a source (link to blog post, documentation, guidelines) where the person could learn more. Harshit is currently the Director of Product Marketing at LambdaTest.
This is one of the oldest, easiest and most intuitive ways to engage in peer code review. When one developer’s code is ready, a colleague sits down at their workstation and looks at the code, and the developer can explain why they wrote it the way they did. When a particular piece of code is ready to be reviewed, the file is emailed to that colleague for review as soon as the workflow permits. While this approach is certainly more flexible and adaptable than traditional techniques, email threads of suggestions and disagreements can quickly become cluttered. It is also much more difficult to share code reviews with other members of the team. A code review is a process where someone other than the author of a piece of code reviews that code.

This approach involves a colleague joining you for a session where they review your code as you articulate your thought process. While it’s an informal and straightforward method, it could be enhanced by incorporating tracking and documentation measures. Here, developers jointly navigate the same code, offering instantaneous feedback and mutually scrutinizing each other’s work. This method encourages mentorship and cooperation, yet it might compromise on impartiality and may demand more time and resources. Under this approach, when what is code review the code is ripe for review, it gets dispatched to colleagues soliciting their feedback.
Team members share knowledge and can quickly overcome difficulties by working through ideas together and drawing on their expertise. A key advantage of LLMs is their ability to generate explicit, human-like comments and explanations, making code reviews more understandable and accessible. This is particularly beneficial for junior developers who are still learning best practices.
It’s based on a formal process where testers follow a structured process to find issues in the code. Leading QA teams are achieving 70% more coverage with Testsigma Copilot. Use Gen-AI to create automated tests with prompts, user stories, and designs. Step 9 − Once the reviewers are satisfied with the code changes, the code is approved for merging.
There are a few common Agile-friendly approaches to code review, each with its limitations. An automated code review is a process in which static code analysis tools are used to automatically review and analyze the source code for potential issues and coding standard violations. Automated code review accelerates the identification and resolution of code issues and improves code quality (reliability, security, maintainability). Traditional code review processes can be time-consuming and are not immune to developer errors.
These tools offer a structured framework for conducting reviews, seamlessly integrating them into the larger development workflow. With the help of tools, the entire process of code review becomes more organized and streamlined. The QA team member does not need to have coding experience to participate. It’s helpful to pair the quality analyst with an experienced developer, so they can review the code together. A software tester might find the code a bit intimidating in the beginning.It is best to pair up with an experienced developer for code reviewing.
Ensure that there is appropriate test code coverage and that the tests are testing the functionality correctly. Large classes or methods, redundant code, magic numbers, or excessive complexity are examples. If you notice a code smell, it’s worth talking about and possibly refactoring.
- Relying too much on AI tools can lead to a decline in developers’ manual code review skills.
- By identifying issues early in the software development process when they’re easier to fix, code reviews help development teams save time and money.
- Understand more about them and when you doubt any change, add your comments and question the coder.
- It provides an opportunity for team members to learn from each other, share insights, and collectively elevate their coding skills.
- The reviewer checks the code for bugs, logical errors, coding standards and best practices.
- Step 8 − The author incorporates the changes and may have multiple discussions with the reviewers till all the issues are addressed and resolved in the code.
Team members review the code, provide feedback, and discuss changes before the pull request is merged into the main branch. With this approach, developers are allowed to commit or merge their changes into the main codebase without a pre-commit review. After the changes are committed, these reviewed code are conducted in the main branch. This approach may be more suitable for teams that value speed and agility during development but still want to ensure code quality through post-merge reviews. Gitea is open-source projects that provide lightweight and self-hosted Git services.
The objective of code review is to enhance the quality, maintainability, stability, security etc of the software which bring positive results to the project. Also, the findings from the code review promote sharing knowledge and learnings among the team members. Github effect’s on code review can be felt by the increasing amount of reviews that development teams are actually doing.
It analyzes the evolution of your codebase over time and identifies social patterns and hidden risks. CodeScene offers cloud-based plans, including a free option for public repositories on GitHub, and on-premise solutions. If the team is small, its lead developer conducts code review, monitoring the project and the quality of the code written by others. In this article, we will tell you how the whole process works and what are the pros and cons of such work. If you are working in an agile environment, you may have come across the term ‘code review’.
