Module `Base_quickcheck.Test`

Use the Test module to run randomized tests. Each randomized test needs a generator, a shrinker, and a property to test.

module type S = Base_quickcheck__.Test_intf.S

module Config : sig ... end

val default_config : Config.t: Defaults to a deterministic seed, shrink_count and test_count of 10_000 each, and sizes ranging from 0 to 30.

val run : f:('a -> Base.unit Base.Or_error.t) -> ?⁠config:Config.t -> ?⁠examples:'a Base.list -> (module S with type t = 'a) -> Base.unit Base.Or_error.t: Tests the property f, failing if it raises or returns Error _. Tests f first with any examples, then with values from the given generator. Only random values count toward the test_count total, not values from examples.

val run_exn : f:('a -> Base.unit) -> ?⁠config:Config.t -> ?⁠examples:'a Base.list -> (module S with type t = 'a) -> Base.unit: Like run, but raises on failure.

val with_sample : f:('a Base.Sequence.t -> Base.unit Base.Or_error.t) -> ?⁠config:Config.t -> ?⁠examples:'a Base.list -> 'a Generator.t -> Base.unit Base.Or_error.t: Calls f with the sequence of values that run would get in the same configuration.

val with_sample_exn : f:('a Base.Sequence.t -> Base.unit) -> ?⁠config:Config.t -> ?⁠examples:'a Base.list -> 'a Generator.t -> Base.unit: Like with_sample, but raises on failure.
