Javascript 组件没有'；我测试时不渲染

我有一个很奇怪的问题。我使用

jasmine 2.0

，

react 0.13.3

，

react路由器0.13.3

和其他软件包。我有一个测试套件，它无法

找到DerenderedomComponentWithTag（）

。请考虑确切的例子：

React = require('react')
TestUtils = require('react/addons.js').addons.TestUtils
ReactRouterContext = require('../../helpers/react_router_context_helper.coffee')

NewSession = require('../../../../app/coffee/components/sessions/new.coffee')
subject = ReactRouterContext(NewSession)

describe 'NewSession', ->
  it 'should send the query after clicking on the button', ->
    instance = TestUtils.renderIntoDocument(<subject />)
    h3 = TestUtils.findRenderedDOMComponentWithTag(instance, 'h3') # can't find at least one h3 tag

  it 'should render wrong login/password on error', ->
    pending()

  it 'should process user after successful login', ->
    # localStorage
    # alt.js
    # redirect
    pending()

---

这似乎很愚蠢，但我只需要将

主题

替换为

主题

。现在，把我的变量看作是组件类，而不是div标签。

Subject = ReactRouterContext(NewSession)
instance = TestUtils.renderIntoDocument(<Subject />)

Subject=ReactRouterContext（新闻会话）
instance=TestUtils.renderIntoDocument（）

# react_router_context_helper.coffee
React = require('react')
objectAssign = require('object-assign')

module.exports = (Component, props, stubs) ->
  RouterStub = ->
  objectAssign RouterStub, {
    makePath: ->
    makeHref: ->
    transitionTo: ->
    replaceWith: ->
    goBack: ->
    getCurrentPath: ->
    getCurrentRoutes: ->
    getCurrentPathname: ->
    getCurrentParams: ->
    getCurrentQuery: ->
    isActive: ->
    getRouteAtDepth: ->
    setRouteComponentAtDepth: ->
  }, stubs

  React.createClass
    childContextTypes:
      router: React.PropTypes.func
      routeDepth: React.PropTypes.number
    getChildContext: ->
      {
        router: RouterStub
        routeDepth: 0
      }
    render: ->
      React.createElement Component, props

Subject = ReactRouterContext(NewSession)
instance = TestUtils.renderIntoDocument(<Subject />)
