  • Patent number: 8745588
    Abstract: A method for processing test results from testing operation of software. A test result of pass, fail status, or unperformed is received for each test case of a test performed for each release of the software. A group to which each test belongs is ascertained. A test result stability index is calculated for each test case as being proportional to a total number of consecutive releases that include and are prior to the last release of the software such that the test result for each of the consecutive releases denotes a pass. A module stability index is calculated for each test case as being a summation over a product of a weight at each release and a binary stability indicator of 0 at each release for which the test result is changed from that of the immediately prior release and 1 at every other release.

  • Patent number: 8707268
    Abstract: A method and system for processing test results from testing operation of software. A test result of pass, fail status, or unperformed is received for each test case of a test performed for each release of the software. A group to which each test belongs is ascertained which determines a group identifier of the group to which each test belongs. A test result stability index is calculated for each test case as being proportional to a total number of consecutive releases that include and are prior to the last release of the software such that the test result for each of the consecutive releases denotes a pass. The group identifier and the test result stability index are stored in a hardware storage unit.
