1. A method implemented in a computer infrastructure having computer executable code tangibly embodied on a computer readable storage memory having programming instructions configured to: receive a tool error output determined by a code inspection service; compare the tool error output to a listing of possible error outputs for a plurality of code inspection tools; determine an identification of a code inspection tool that generated the tool error output based on the comparison; select at least one defect classification mapping profile based on the identified code inspection tool; quantify occurrences of each of the possible tool error outputs for each of the plurality of code inspection tools; map the tool error output to one or more of the output classifications using the selected at least one defect classification mapping profile; and quantify a number of defects of the possible tool error outputs based on the one or more of the output classifications.
