Overview

Check if code owners are consistent between a git repository and the CODEOWNERS file. It compares what’s being changed in the PR and check if the current files and folders are also being declared in the CODEOWNERS file. By default (:validate_owners property) it also reads OWNERS with list of all possible/valid owners and validates every owner in CODEOWNERS is defined in OWNERS
