Question

我在生产代码中有这个：

$(document).ready ->      
  if $( "#accordion" ).length > 0
    $( "#accordion" ).accordion()

哪个有效，我想测试一下：

describe "Non-MVCd stuff", ->
  beforeEach ->
    spyOn( $('#accordion').prototype, 'accordion' )
    if $("#accordion").length > 0 
      $("#accordion").accordion()

  describe "accordion", ->
    it 'works', ->
      expect( $('#accordion' ).length ).toBe( 1, 'the element must be there.' )
      expect( $('#accordion').prototype.accordion ).toHaveBeenCalled()

我收到此错误：

spyOn could not find an object to spy upon for accordion()
TypeError: $(...).prototype is undefined in http://pi.local:3011/assets/spec/views/utils_spec.js?body=1 (line 14)

没有原型它也不起作用（和$（“＃accordion”）。原型未定义）：

describe "Non-MVCd stuff", ->
  beforeEach ->
    spyOn( $('#accordion'), 'accordion' )
    if $("#accordion").length > 0 
      $("#accordion").accordion()
  describe "accordion", ->
    it 'works', ->
      expect( $('#accordion' ).length ).toBe( 1, 'the element must be there.' )
      expect( $('#accordion').accordion ).toHaveBeenCalled()

只需使用以下代码来监视对象函数，就像这样。

spyOn($.fn, 'accordion' )

或者正常方法。

spyOn([ObjectName].prototype, '[methodName]' )
