Code Review

What is Code Review?

Code review is the systematic examination of source code by peers to find bugs, verify adherence to coding standards, and improve overall code quality and maintainability before it is merged or released.

Types of Code Review

• Informal/Peer Review: A quick, ad-hoc check by a colleague, often done during pull requests.
• Formal/Checklist-driven Review: A structured process similar to an inspection, using checklists and defined criteria.
• Pair Programming: Continuous, real-time code review as two developers write code together.
• Tool-assisted Review: Static analysis tools automatically flag style violations, security issues, or code smells.

Benefits of Code Review

• Catches bugs and design issues early, before they reach testing.
• Spreads knowledge of the codebase across the team.
• Encourages consistent coding standards and best practices.
