jsfiddle test of the coffeescript class Options此处还包含options.coffee：
class Options
constructor: () ->
# public accessible
defaults:
lang: "en"
aspectRatio: 1.35
options_spec.coffee：
Options = require 'lib/options'
describe "Options", ->
options = null
beforeEach ->
console.log 'in beforeEach'
console.log options
console.log Options
options = new Options()
it "should not be undefined", ->
console.log 'in should not be undefined'
expect(options).not.toBeUndefined()
我似乎无法让最简单的测试运行，当我运行cake test时会产生以下结果：

这是我与早午餐，蛋糕和业力茉莉花的第一次复飞，我无法完全了解这个问题或从哪里开始。思考/指点/答案/建议阅读会很棒！
答案 0 :(得分：3)
module.exports =。
所以完整的Options类看起来像：
module.exports = class Options
constructor: () ->
# public accessible
defaults:
lang: "en"
aspectRatio: 1.35
尽管如此，欢迎指点和任何推荐读物！
