APPARATUS, METHOD, AND STORAGE MEDIUM FOR GENERATING INPUT PARAMETER

The database generation unit refers to the source program, lists routes passed during the execution of the source program, and enters the route information in the route information database. As a result of executing the load module, the relevant information such as a value of a parameter used when a route is passed, and an execution state are entered in the route information database. The similar route determination unit extracts from the route information database a route path not passed, determines a similar route from passed routes, and transmits the relevant information in the input parameter generation unit. Based on the information about similar routes, the input parameter generation unit generates and outputs an input parameter required to pass a non-passed route path and a condition to be satisfied by an input parameter.
