What makes a good code review?

Good code reviews look at the change itself and how it fits into the codebase. They will look through the clarity of the title and description and “why” of the change. They cover the correctness of the code, test coverage, functionality changes, and confirm that they follow the coding guides and best practices.

How code quality is measured?

It relates to the number of defects and availability of the software. Number of defects can be measured by running a static analysis tool. Software availability can be measured using the mean time between failures (MTBF). Low defect counts are especially important for developing a reliable codebase.
