Let Tbe a regression test for program P . Let X ={<>,<>, ... ,<>}, k > 0 be a set of sequences of tests such that each sequence contains tests from Tand that each test in T occurs in at least one sequence in X. Modify PrTest to account for the requirement that if any <> is selected for execution, the given sequencing constraint is not violated. Note that the sequences in X might not be disjoint.
