lin_test ~count:c ~name:n builds a parallel test with the name n that iterates c times. The test fails if one of the generated programs is not sequentially consistent. In that case it fails, and prints a reduced counter example.

neg_lin_test ~count:c ~name:n builds a negative parallel test with the name n that iterates c times. The test fails if no counter example is found, and succeeds if a counter example is indeed found, and prints it afterwards.

stress_test ~count:c ~name:n builds a parallel test with the name n that iterates c times. The test fails if an unexpected exception is raised underway. It is intended as a stress test to run operations at a high frequency and detect unexpected exceptions or crashes. It does not perform an interleaving search like lin_test and neg_lin_test.
