ReferenceError: CoffeeScript + JsTestDriver + Qunit

Question

I'm currently looking for TDD with CoffeeScript and JsTestDriver, however, I'm stuck on a ReferenceError released by JsTestDriver.

Some information:

• Using IntelliJ JsTestDriver Plugin
• Testing through Chrome
• The configured JsTestDriver is the same as on: http://code.google.com/p/js-test-driver/wiki/QUnitAdapter
• Writing Tests in CoffeeScript
• CoffeeScript is compiled in javascript and placed in the configured directories before running the test.

Config

server: http://Mark-PC:9876/capture load: - js/lib/main/*.js - js/lib/test/sinon.js - js/lib/test/qunit.js - js/lib/test/equiv.js - js/lib/test/QUnitAdapter.js - js/coffee/main/controllers/*.js - js/coffee/main/models/*.js - js/coffee/test/controllers/*.js 

controller

 class PortfolioController extends Backbone.Controller constructor: -> test: (a, b) -> return a + b 

Test code

 module("PortfolioController", { setup: -> @routeSpy = sinon.spy() teardown: -> window.location.hash = "" }) test 'indexRoute', -> c = new PortfolioController equals c.test(1, 1), 2, "1 + 1 = 2" 

Problem

JsTestDriver throws an error

 ReferenceError: PortfolioController is not defined ReferenceError: PortfolioController is not defined at Object. (http://mark-pc:9876/test/js/coffee/test/controllers/PortfolioController.test.js:12:5) at [object Object].test indexRoute (http://mark-pc:9876/test/js/lib/test/QUnitAdapter.js:40:15) 

I tried:

• Removing dependencies like jQuery, BackBone, etc.
• Remote Qunit adapter and tried using jstestdriver statements
• A class is added inside the test itself, then it worked

Sounds like some kind of export problem or prototype conflict?

Answer 1

It looks like you need to make PortfolioController global, perhaps by adding

 root = window ? global root.PortfolioController = PortfolioController 

end of file or just replacing

 class PortfolioController extends Backbone.Controller 

with

 class @PortfolioController extends Backbone.Controller 

using the fact that this is a global root in this context.

CoffeeScript never exports anything outside the scope of a file automatically; You must do this explicitly. See my explanation of this behavior here .
