TEST SELECTION BASED ON AN N-WISE COMBINATIONS COVERAGE

Based on a functional coverage by a test suite, a functional coverage model of a System Under Test (SUT) may be defined to represent all covered combinations of functional attributes. Based on an n-wise combination criteria, a subset of the possible combinations of values may be determined. A subset of the test suite may be selected such that the selected subset is operative to cover the subset of the determined possible combinations of values. The disclosed subject matter may be used to reduce a size of the test suite while preserving the n-wise combinations coverage of the original test suite.
