所以我正在尝试使用用 CoffeeScript 编写的 Mocha 和 Chai 运行单元测试。我知道 Mocha 从 1.0 开始就排除了咖啡脚本，所以我传递了编译器标志mocha --compilers coffee:coffee-script。最终发生的是，每当我尝试在测试中要求一个文件时，编译器都会抱怨这个错误。否则它运行良好。

/usr/local/lib/coffee-script/lib/coffee-script.js:36
      throw err;
            ^
TypeError: In /Users/chietala/workspaces/twl/test/buttonTest.coffee, Array.prototype.indexOf called on null or undefined

我的测试文件中的所有内容如下

  ButtonConsumer = require '../button/base/coffee/ButtonConsumer'

ButtonConsumer 看起来像这样。

 class ButtonConsumer
  constructor: ->

目录结构是

/
   test
      buttonTest.coffee
   button
      base
        coffee
           ButtonConsumer.coffee

这是非常简单的骨头，这就是为什么我真的很困惑。我正在运行 Node v0.8.1、Coffeescript v1.2.0 和 mocha 1.2.2。

Mocha 不适用于 CoffeeScript 1.2。升级到 1.3.3 工作正常。
