Abstract: Mechanisms are provided for identifying execution paths in computer application logic. A control flow graph is generated for the computer application logic based on source code and an execution log. Paths of the control flow graph are identified that have operators matching operators having execution counts in the execution log. An operator list for each path is generated specifying operators in the path. An operator count expression is generated for each operator in the operator list for each path. For each path, a relationship is generated between the path's operator count expression and actual execution count information for operators in the path's operator list. An execution possibility value is estimated for each path based on the relationships for each path, and a second set of paths having execution possibility values indicating they are possible execution paths of the computer application logic is output.
