“…In this case, software failures are discovered, resulting in the interaction of several input parameters called t-way tests; t refers to the strength of the interaction [6,7]. CA can be formulated as CA (N, v P , t), where N * P defines the input matrix [0, 1,2 ..., up to (v -1)], so that each set of t-columns include at least once of each possible t-tuple, where v is a value, P the degree and t the strength [4,8]. Several strategies, as well as improved t-way combinatorial testing techniques, have also been developed to optimize any algorithm and to generate smaller test sequences or an almost optimal number of tests.…”
