SYSTEM TESTING INFRASTRUCTURE FOR ANALYZING SOFT FAILURES IN ACTIVE ENVIRONMENT

Abstract:

A method for testing a system under test (SUT) in an active environment includes generating, by a testing system, a set of tests for testing the SUT, the tests generated based on a coverage model of the SUT, wherein the coverage model uses several attributes. The method further includes creating, by the testing system, a minimal set of tests from the generated tests by selecting tests for a disjoint set of attributes from the several attributes of the coverage model. The method further includes executing, by the testing system, the minimal set of tests on the SUT for analyzing a soft failure of the SUT in the active environment, wherein the soft failure occurs in the active environment during execution of the SUT based at least in part on a parameter of the active environment.
