Question

我们在Rails 4.1应用程序中开始了集成Reactjs的过程。问题是现在有很多功能被破坏了。

以下是测试的堆栈：

黄瓜
水豚
Poltergeist（通过phantomjs）
Rspec的

例如，有黄瓜功能：

@javascript @services

Feature: Manage Service
  Scenario Outline: Publish and archieve
    Given the individual user
    When I visit services page
    And I click on I18n translation for key "views.labels.add"
    And I fill service's fields and choose price as "<price>"
    And I click on I18n translation for key "<submit_btn>"
    Then I should see I18n translation for key "<message>"
    And Created service should have 1 tag

  Examples:
    | submit_btn                 | price      | message                                       |
    | views.labels.publish       | fixed      | views.messages.notices.add.created            |
    | views.labels.publish       | negotiated | views.messages.notices.add.created            |

当我运行此测试时，我看到了这个错误：

  One or more errors were raised in the Javascript code on the page. If you don't care about these errors, you can ignore them by setting js_errors: false in your Poltergeist configuration (see documentation for details).

  TypeError: 'undefined' is not a function (evaluating 'RegExp.prototype.test.bind(
      /^(data|aria)-[a-z_][a-z\d_.\-]*$/
    )')
  TypeError: 'undefined' is not a function (evaluating 'RegExp.prototype.test.bind(
      /^(data|aria)-[a-z_][a-z\d_.\-]*$/
    )')

我找到了解决方案。您需要使用shim。我把文件放在vendor/assets/javascripts/es5-shim.js。

之后你需要初始化这个垫片。请注意，垫片应该 BEFORE 响应初始化，这很关键！

<强>的application.js

//= require es5-shim
//= require react
//= require react_ujs

之后测试开始再次起作用。

Capybara，Poltergeist和Reactjs - 'undefined'不是一个功能
