QCheck_alcotest (qcheck-alcotest.QCheck

Alcotest backend for QCheck

We use environment variables for controlling QCheck here, since alcotest doesn't seem to provide a lot of flexibility.

QCHECK_VERBOSE if "1" or "true", will make tests verbose
QCHECK_SEED if an integer, will fix the seed
QCHECK_LONG is present, will trigger long tests

val to_alcotest : 
  ?colors:bool ->
  ?verbose:bool ->
  ?long:bool ->
  ?debug_shrink:Stdlib.out_channel option ->
  ?debug_shrink_list:string list ->
  ?speed_level:Alcotest.speed_level ->
  ?rand:Stdlib.Random.State.t ->
  QCheck2.Test.t ->
  unit Alcotest.test_case

Convert a qcheck test into an alcotest test.

The optional speed_level is `Slow by default, meaning Alcotest can skip such a test when the -q flag is passed. Passing `Quick instead means the test is always run.

In addition to speed_level and the environment variables mentioned above, you can control the behavior of QCheck tests using optional parameters that behave in the same way as the parameters of QCheck_base_runner.run_tests.
