Types and functions for creating and structuring unit test suites.

exception TestFailure of string

The exception thrown by failing tests.

type result =

| Error of exn
(*
An unexpected error occurred in the test.
*)
| Fail of string
(*
An assertion failed in the test.
*)
| Pass
(*
The test passed.
*)

The result of running a single testcase.

type outcome = {

label : string;
result : result;
time_s : float;

}

The outcome of a test: its label, result, and time taken to run.

val string_of_result : result -> string

module Sync : sig ... end

module Async : sig ... end

type t =

| TestCase of string * Async.test_fun
(*
A labelled single test.
*)
| TestList of string * t list
(*
A labelled list of tests.
*)

A labelled wrapper around a test or list of suites.

val (>::) : string -> Sync.test_fun -> t

Convenience function to create a suite from a label and a Sync.test_fun.

val (>:~) : string -> Async.test_fun -> t

Convenience function to create a suite from a label and an Async.test_fun.

val (>:::) : string -> t list -> t

Convenience function to create a suite from a label and a list of suites.

val assert_true : ?label:string -> bool -> unit

assert_bool label value returns unit if value is true, and otherwise raises TestFailure.

val assert_equal : 
  ?equal:('a -> 'a -> bool) ->
  ?label:string ->
  ?printer:('a -> string) ->
  'a ->
  'a ->
  unit

assert_equal a b returns unit if a is equal to b, and otherwise raises TestFailure.

val assert_raises : ?label:string -> exn -> (unit -> unit) -> unit

assert_raises e task returns unit if task () raises e, and otherwise raises TestFailure.

val assert_raises_string : ?label:string -> string -> (unit -> unit) -> unit

assert_raises_string str task returns unit if task () raises an exception e for which Printexc.to_string e = str, and otherwise raises TestFailure.
