val qcheck_wrap : QCheck.Test.t list -> unit Alcotest.test_case list

Wrap QCheck tests into Alcotests.

val qcheck_eq : 
  ?pp:(Stdlib.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.

val qcheck_eq' : 
  ?pp:(Stdlib.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.

val int64_range : int64 -> int64 -> int64 QCheck.arbitrary

int64_range 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.

val of_option_gen : 'a option QCheck.Gen.t -> 'a QCheck.Gen.t

of_option_gen gen converts a generator gen of optional values into a generator of values by rerunning the generator if the generated value was a None until a Some is generated.

Be careful: if None is always returned, this hangs forever!

val of_option_arb : 'a option QCheck.arbitrary -> 'a QCheck.arbitrary

of_option_arb arb converts an arbitrary arb of optional values into an arbitrary of values.

Generation of values is delegated to of_option_gen (retries on None values until a Some is generated).
Shrinking uses the input shrinker but ignores None values.

Be careful: if None is always returned, this hangs forever!
