Omtl

An OCaml minimalist testing framework with zero dependencies.

---

The purpose of this framework is to provide an intuitive command line interface and write simple tests quickly.

Usage

./test/test_omtl.ml

(* A module with functions to test *)
module Suit = struct
  let pass () = ()

  let failed () = "Failed !!!"
end

(* The tests *)
let test_pass () = Suit.pass () |> ok

let test_failed () = Suit.failed () |> err

let test_failure () = failwith "Take it easy, this is just an example of a failed test"

let test_exception () = raise Not_found

let test_function_running_time () =
  for _ = 0 to 100000 do
    ()
  done;
  Ok ()


(* Run it *)
let _ =
  "My_String"
  +:> [
        "pass" >== test_pass;
        "failed" >== test_failed;
        "Examples of test failures" >== test_failure;
        "Examples of undefined exception" >== test_exception;
        "Test function running time" >== test_function_running_time;
      ]
  |> run ~force:true ~backtrace:true ~callstack:true
