purescript-spec-mocha

purescript-spec-mocha is a runner and reporter for purescript-spec that run tests and reports the results using the Mocha interface (describe, it etc). This enables you to use purescript-spec together with mocha and karma, and thus run tests in web browsers, as well as NodeJS.

bower install purescript-spec-mocha

module Main where

import Prelude
import Control.Monad.Eff (Eff)
import Test.Spec (SpecEffects, describe, it)
import Test.Spec.Assertions (shouldEqual)
import Test.Spec.Mocha (MOCHA, runMocha)

main :: Eff (SpecEffects (mocha :: MOCHA)) Unit
main = runMocha do
  describe "your feature" do
    it "works" $
      (1 + 1) `shouldEqual` 2

If you bundle your compiled PureScript it can be run with mocha bundle.js or using Karma and karma-mocha.

pulp browserify -I test --main Test.Main > bundle.js
mocha bundle.js

If you want to mix in Purescript tests with existing Javascript (or Coffeescript) Mocha tests running in the browser, you'll need to import the file and call the function exported by your Purescript test. E.g. combining the example from Running Mocha in the Browser with the above Purscript spec, you'll need:

<!-- test/index.html -->
...
  <script>mocha.setup('bdd')</script>
  <script src="all_tests.js"></script>
  <script>
    mocha.checkLeaks();
    mocha.globals(['jQuery']);
    mocha.run();
  </script>
...

// all_tests.js
require('test.array.js');               // Javascript specs load when the the file is parsed.
require('test.object.js');
require('test.xhr.js');

{main} = require('my_purescript_spec');
main();                                 // Purescript specs load when the function is called.

See docs on Pursuit.

This project's tests include some failures to test the Mocha integration. Thus, use run_tests.sh instead of pulp test to check that everything is all right.
