ReferenceError：CoffeeScript + JsTestDriver + Qunit [英] ReferenceError: CoffeeScript + JsTestDriver + Qunit

问题描述

目前我正在研究TDD与CoffeeScript和JsTestDriver，但我被困在由JsTestDriver抛出的ReferenceError。

一些信息：

• 使用IntelliJ JsTestDriver插件


• 通过Chrome测试


• 已配置JsTestDriver的方式与 http：// code相同。 google.com/p/js-test-driver/wiki/QUnitAdapter


• 在CoffeeScript中编写测试


• 将CoffeeScript编译为javascript并在运行测试之前放入配置的目录

配置 b

  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 
 
  

控制器 / b>

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

测试代码

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

>

JsTestDriver引发错误

  ReferenceError：PortfolioController未定义
 ReferenceError：没有在Objects定义PortfolioController 
。 （http：// mark-pc：9876 / test / js / coffee / test / controllers / PortfolioController.test.js：12：5）
 at [object Object] .test indexRoute（http： pc：9876 / test / js / lib / test / QUnitAdapter.js：40：15） 

• 删除依赖项（如jQuery，BackBone等）


• 删除了Qunit适配器和尝试使用jstestdriver声明


• 在测试本身内添加了一个类，然后工作

似乎有些出口问题或原型冲突？

解决方案

听起来像你需要 PortfolioController 全局，也许通过添加

  root =全局
 root.PortfolioController = PortfolioController 
  

文件的结尾， / p>

  class PortfolioController extends Backbone.Controller 
  

与

  class @PortfolioController extends Backbone.Controller 
  
 
 
 
利用这个是该上下文中的全局根。
 
 
 
 CoffeeScript不会自动导出超出文件范围的任何内容;你必须明确做到。请参阅我对此行为的解释此处。
 
Currently I'm looking into TDD with CoffeeScript and JsTestDriver however I'm stuck on a ReferenceError thrown by JsTestDriver.

Some info:


Using the IntelliJ JsTestDriver plugin
Testing via Chrome
Configured JsTestDriver the same way as on: http://code.google.com/p/js-test-driver/wiki/QUnitAdapter
Writing the tests in CoffeeScript
CoffeeScript is compiled to javascript and put in the configured directories before the test is run


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 a 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)
Tried:


Removing dependancies such as jQuery, BackBone, etc
Removed Qunit adapter and tried with jstestdriver asserts
Added a class inside the test itself, then it worked


Seems like some kinda exporting issue or prototype conflict?
解决方案
Sounds like you need to make PortfolioController a global, perhaps by adding
root = window ? global
root.PortfolioController = PortfolioController
the end of the file, or by simply replacing
class PortfolioController extends Backbone.Controller
with
class @PortfolioController extends Backbone.Controller
taking advantage of the fact that this is the global root in that context.

CoffeeScript never exports anything beyond a file's scope automatically; you have to do it explicitly. See my explanation for this behavior here.
