Quickcheck.Configuremodule Config : Quickcheck_configinclude Quickcheck_intf.Quickcheck_configval default_seed : Quickcheck_intf.seeddefault_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_sizes : Base.Int.t Sequence.tdefault_sizes determines the default sequence of sizes used in generating values.
val default_trial_count : Base.Int.tdefault_trial_count determines the number of trials per test, except in tests that explicitly override it.
val default_can_generate_trial_count : Base.Int.tdefault_can_generate_trial_count determines the number of trials used in attempts to generate satisfying values, except in tests that explicitly override it.
val default_shrink_attempts : Quickcheck_intf.shrink_attemptsdefault_shrink_attempts determines the number of attempts at shrinking when running test or iter with ~shrinker and without ~shrink_attempts
val random_value : ?seed:Quickcheck_intf.seed -> ?size:Base.Int.t -> 'a Base_quickcheck.Generator.t -> 'arandom_value gen produces a single value chosen from gen using seed.

It stops successfully after trials successful trials or if gen runs out of values. It raises an exception if f raises an exception.

?sexp_of:('a -> Base.Sexp.t) -> ?examples:'a Base.List.t -> 'a Base_quickcheck.Generator.t -> f:('a -> Base.Unit.t) -> Base.Unit.ttest gen ~f is like iter, with optional concrete examples that are tested before values from gen, and additional information provided on failure. If f raises an exception and sexp_of is provided, the exception is re-raised with a description of the random input that triggered the failure. If f raises an exception and shrinker is provided, it will be used to attempt to shrink the value that caused the exception with re-raising behaving the same as for unshrunk inputs.

Any exceptions raised by f are also treated as failures.

It tests gen by generating up to trials values and passing them to f. Once a value satisfies f, the iteration stops. If no values satisfy f, test_can_generate raises an exception. If sexp_of is provided, the exception includes all of the generated values.

It tests gen by generating up to trials values and making sure at least distinct_values of the resulting values are unique with respect to compare. If too few distinct values are generated, test_distinct_values raises an exception. If sexp_of is provided, the exception includes the values generated.
