Alcotest_async enables testing functions which return an Async deferred. run returns a deferred which will run the tests when scheduled.

include Alcotest.Core.S with type return = unit Async_kernel.Deferred.t

type return = unit Async_kernel.Deferred.t

type speed_level = [

| `Quick
| `Slow

]

Speed level of a test. Tests marked as `Quick are always run. Tests marked as `Slow are skipped when the `-q` flag is passed.

type 'a test_case = string * speed_level * ('a -> return)

A test case is an UTF-8 encoded documentation string, a speed level and a function to execute. Typically, the testing function calls the helper functions provided below (such as check and fail).

exception Test_error

The exception return by run in case of errors.

type 'a test = string * 'a test_case list

A test is an US-ASCII encoded name and a list of test cases. The name can be used for filtering which tests to run on the CLI

val list_tests : 'a test list -> return

Print all of the test cases in a human-readable form

type 'a with_options =
  ?and_exit:bool ->
  ?verbose:bool ->
  ?compact:bool ->
  ?tail_errors:[ `Unlimited | `Limit of int ] ->
  ?quick_only:bool ->
  ?show_errors:bool ->
  ?json:bool ->
  ?filter:(Re.re option * Alcotest.Core.IntSet.t option) ->
  ?log_dir:string ->
  'a

The various options taken by the tests runners run and run_with_args:

and_exit (default true). Once the tests have completed, exit with return code 0 if all tests passed, otherwise 1.
verbose (default false). Display the test std.out and std.err (rather than redirecting to a log file).
compact (default false). Compact the output of the tests.
tail_errors (default unlimited). Show only the last N lines of output of failed tests.
quick_only (default false). Don't run tests with the `Slow speed level.
show_errors (default false). Display the test errors.
json (default false). Print test results in a JSON-compatible format.
log_dir (default "$PWD/_build/_tests/"). The directory in which to log the output of the tests (if verbose is not set).
