A software reduction component may be provided with a software interface. The software interface may define a test case load method also define a model load method. The reduction component has logic for reducing test cases loaded via implementations of the method definitions. An implementation of the software interface can be provided. The implementation has an implementation of the defined test case load method, which can parse test cases in a first format and can build data structures corresponding to the test cases that are accessible by the software reduction component. The implementation can also have an implementation of the defined model load method, which can parse descriptions of models of respective programs and generate therefrom model data structures that model behavior of the respective programs.
