    val default_seed : Quickcheck_intf.seed

`default_seed` is used initialize the pseudo-random generator that chooses random values from generators, in each test that is not provided its own seed.

    val default_trial_count : int

`default_trial_count` determines the number of trials per test, except in tests that explicitly override it.

    val default_trial_count_for_test_no_duplicates : [ `Constant of int | `Scale_of_default_trial_count of float ]

`default_trial_count_for_test_no_duplicates` determines the number of trials when running `test_no_duplicates` without `~trials`, either as a constant or as a factor of `default_trial_count`.

    val default_attempts_per_trial : float

`default_attempts_per_trial` determines the maximum number of attempts to generate inputs for trials, as a multiplier for the number of trials, except in tests that explicitly override it.
