ABSTRACT
Combinatorial testing applies factor covering arrays to test all t-way combinations of input or configuration state space. In some testing situations, it is not practical to use covering arrays, but any set of tests with n parameters covers at least some proportion of t-way combinations up to t ≤ n. This report describes measures of combinatorial coverage that can be used in evaluating the degree of t-way coverage of any test suite, regardless of whether it was initially constructed for combinatorial coverage.
