Code review, also referred to as peer review, is a systematic examination of software source code. It's conducted to find bugs and improve overall quality of the software.
There are at least two roles that are always present in a code review:
- Author is the person responsible for creating the code being reviewed.
- Reviewer is the person responsible for examining the code and reporting the findings to the author.
