val lin_test : count:int ->name:string ->QCheck.Test.t
lin_test ~count:c ~name:n builds a concurrent 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.
val neg_lin_test : count:int ->name:string ->QCheck.Test.t
neg_lin_test ~count:c ~name:n builds a negative concurrent 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.
