US Patent 10204028 Rule spaces and architecture root detection

Errors in software may be detected via the use of design rule spaces and architecture root detection. Design rule spaces may reveal multiple overlapping modular structures of a software system, and reveal structural relations among error-prone files and structural problems contributing to error-proneness. Root detection may extract a few groups of architecturally connected files, which may be connected through problematic architecture relations that propagate errors among these files, and thus influence system error-proneness. The root detector may locate the core architecturally connected file groups that contribute to the error-proneness of a system. The root detection process may, beginning with a set of error-prone files, search and link other files that are architecturally related. The output of the root detection process may be a set of design rule spaces ordered by the number of error-prone contained therein.
