FLEXIBLE TEST PROGRAM GENERATION BY ALTERING PREVIOUSLY USED RESOURCES

Abstract:

A method for flexible test program generation is described that alters previously used resources. The method includes scanning, by a test generator, a set of instructions that have been executed by a system under test (SUT) using a reference model of the SUT. The method further includes identifying, by the test generator, a resource for using in a test program by determining an allocation of a first value to the resource by a subset of instructions from the set of instructions, wherein the first value of the resource is not used after the allocation. The method further includes modifying the subset of instructions to allocate a second value to the resource, and adding to the set of instructions, at least one instruction that uses the second value to perform a predetermined operation. The SUT is tested based on a result of the predetermined operation that uses the second value.
