1. A computer program product comprising a computer readable storage memory or device having readable program code embodied in the storage memory or device, wherein the computer readable storage memory or device is not a transitory signal per se, the computer program product includes at least one component operable to: receive a tool error output determined by one of a plurality of code inspection tools offered, respectively, by one of a plurality of code inspection services; compare the tool error output to a listing of possible error outputs for a plurality of code inspection tools; determine an identification of the one of the code inspection tools, from among the plurality of code inspection tools, that generated the tool error output based on the comparison; select at least one defect classification mapping profile based on the identified one of the code inspection tools; 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 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, wherein the selecting the at least one defect classification mapping profile comprises selecting one or more designated defect classification mapping profiles, which each comprise: the listing of possible tool error outputs for a particular code inspection tool; and for each of the possible tool error outputs, a corresponding output classification with a common classification schema.
