METHOD AND MACHINE-READABLE MEDIA FOR INFERRING RELATIONSHIPS BETWEEN TEST RESULTS

In one embodiment, a method for inferring relationships between test results receives sequential test data from a tester performing tests on a number of devices under test (DUTs); upon receiving a DUT identifier, determines if a data structure exists for the DUT identified by the one of the DUT identifiers; upon determining that the data structure does not exist, creates the data structure associates i) any test results associated with the one of the DUT identifiers with ii) the data structure; and upon determining that the data structure exists, creates a child data structure, as a child of the data structure, and associates i) the any test results associated with the one of the DUT identifiers with ii) the child data structure, wherein the child data structure inferentially indicates that the test results associated therewith are retest results.
