Patent ID: 7797650

Claim:
A computer-implemented method comprising: receiving a test case that includes a first set of test case effective addresses, a first set of effective segment identifiers, and a first set of virtual segment identifiers; executing the test case using the first set of test case effective addresses, the first set of effective segment identifiers, and the first set of virtual segment identifiers; modifying the first set of test case effective addresses and the first set of effective segment identifiers using an effective address arithmetic function, resulting in a second set of test case effective addresses and a second set of effective segment identifiers; modifying the first set of virtual segment identifiers using a virtual address arithmetic function, resulting in a second set of virtual segment identifiers; and re-executing, by a processor, the test case using the second set of test case effective addresses, the second set of effective segment identifiers, and the second set of virtual segment identifiers.
