Consider the system S in Figure 9.7, which has three input parameters X, Y, and Z. Assume that set D, a set of input test data values, has been selected for each of the input variables such that D(X) = {True, False}, D(Y) = {0, 5}, and D(Z) = {P,Q,R}. Using the orthogonal array method discussed in this chapter, generate pairwise test cases for this system. Compare the results with the test suite generated using the IPO algorithm.
