Module Lib_test.Qcheck2_helpersSource

Sourceval qcheck_wrap : ?verbose:bool -> ?long:bool -> ?rand:Random.State.t -> QCheck2.Test.t list -> unit Alcotest.test_case list

Wrap QCheck tests into Alcotests.

Sourceval qcheck_eq_tests : eq:('a -> 'a -> bool) -> gen:'a QCheck2.Gen.t -> eq_name:string -> QCheck2.Test.t list

qcheck_eq_tests ~eq ~gen ~eq_name returns three tests of eq: reflexivity, symmetry, and transitivity.

eq_name should be the name of the function defining eq. For example, given an equality function defined as let mytype_eq = ..., call qcheck_eq_tests mytype_eq gen "mytype_eq". eq_name is only used for logging.

Sourceval qcheck_eq : ?pp:(Format.formatter -> 'a -> unit) -> ?cmp:('a -> 'a -> int) -> ?eq:('a -> 'a -> bool) -> 'a -> 'a -> bool

qcheck_eq pp cmp eq a b evaluates whether a and b are equal, and if they are not, raises a failure and prints an error message. Equality is evaluated as follows:

  • use a provided eq
  • if no eq is provided, use a provided cmp
  • if neither eq nor cmp is provided, use Stdlib.compare

If pp is provided, use this to print x and y if they are not equal.

Sourceval qcheck_eq' : ?pp:(Format.formatter -> 'a -> unit) -> ?cmp:('a -> 'a -> int) -> ?eq:('a -> 'a -> bool) -> expected:'a -> actual:'a -> unit -> bool

Labeled variant of qcheck_eq. The unit argument is necessary as OCaml requires at least one positional (non-labeled) argument in case of optional arguments.

Sourceval int64_range_gen : int64 -> int64 -> int64 QCheck2.Gen.t

int64_range_gen a b generates an int64 between a inclusive and b inclusive.

Poorman's implementation until https://github.com/c-cube/qcheck/issues/105 is done.

This probably spectacularly crashes if (b - a) > Int64.max_int.

Sourceval int64_strictly_positive_gen : int64 -> int64 QCheck2.Gen.t

int64_strictly_positive_gen x generates an int64 between 1 inclusive and x inclusive.

This will fail if x is not strictly positive.

Sourceval int_strictly_positive_gen : int -> int QCheck2.Gen.t

int_strictly_positive_gen x generates an int between 1 inclusive and x inclusive.

This will fail if x is not strictly positive.

Sourceval uint16 : int QCheck2.Gen.t

uint16 is a generator of unsigned int16 values

Sourceval int16 : int QCheck2.Gen.t

int16 is a generator of signed int16 values

Sourceval uint8 : int QCheck2.Gen.t

uint8 is a generator of unsigned int8 values

Sourceval int8 : int QCheck2.Gen.t

int8 is a generator of signed int8 values

Sourceval string_fixed : int -> string QCheck2.Gen.t

string_fixed n is a generator of strings of length n.

Sourceval bytes_gen : bytes QCheck2.Gen.t

bytes_gen is a QCheck2.Gen.t for bytes.

Sourceval endpoint_gen : Uri.t QCheck2.Gen.t

endpoint_gen is a QCheck2.Gen.t for endpoints (such as tezos-client's --endpoint flag). It returns URLs of the form: (http|https)://(string\.)+(:port)?. It is by no means the most general Uri.t generator. Generalize it if needed.

Sourceval sublist : 'a list -> 'a list QCheck2.Gen.t

A generator that returns a sublist of the given list. Lists returned by this generator are not in the same order as the given list (they are shuffled). This generator can return a list equal to the input list (this generator does not guarantee to return strict sublists of the input list).

Sourceval holey : 'a list -> 'a list QCheck2.Gen.t

A generator that returns lists whose elements are from the given list, preserving the order. For example, given the input list 0, 1, 2, this generator can produce , 0, 0, 2, 1, 2, 1, etc.

Sourcemodule MakeMapGen (Map : Map.S) : sig ... end

Map-related generators.
