Question

我在轨道之外使用Capybara，rspec和poltergeist来运行一些无头集成测试。场景是，有2个选择字段。如果我在第一个选择字段中选择一个值，则会根据第一个选择字段的值填充第二个选择字段。如果我在Mac OSX中使用poltergeist运行我的规范，则规范有效。但是在ubuntu中，它失败了，似乎没有填充第二个选择字段。我的规格也有js: true。

这是我的spec_helper.rb：

require 'capybara/poltergeist'
require 'capybara'
require 'capybara/rspec'
require 'pry'
require 'support/session_helper'
RSpec.configure do |config|

  config.include Capybara::DSL
  config.include Capybara::Poltergeist
  config.include SessionHelper

  Capybara.run_server = false
  Capybara.default_driver = :poltergeist
  Capybara.javascript_driver = :poltergeist
  Capybara.app_host = "http://vps-staging.dropmysite.com"

  options = { js_errors: false }
  Capybara.register_driver :poltergeist do |app|
    Capybara::Poltergeist::Driver.new(app, options)
  end

  config.expect_with :rspec do |expectations|

    expectations.include_chain_clauses_in_custom_matcher_descriptions = true
  end

  config.mock_with :rspec do |mocks|
    mocks.verify_partial_doubles = true
  end

end

编辑添加失败的规范

require 'spec_helper'

feature 'vps-staging', js: true do
  background do
    visit '/'
  end

  let(:timestamp) { Time.now.strftime('%Y-%m-%d_%H-%M-%S') }


  feature 'create private server' do
    background do
      sign_in 'blahblah@blahblah.com'
    end

    it 'successfully creates server' do
      find(:xpath, "//a[@href='/en/private_servers/new']").click

      directory_field = all(".tagit-new")[0].find("input")
      select 'Ubuntu', from: 'distribution'
      select '15.04', from: 'version'
      fill_in 'private_server_profile_name', with: "Auto Test #{timestamp}"
      directory_field.set "/home"
      click_button 'Save'

      visit '/en/dashboard'

      expect(page.text).to have_content "Auto Test #{timestamp}"
    end
  end
end

编辑我发现的另一件事是，这个bug只发生在phantomjs 1.9.8及更低版本上。 2.0工作正常。

正如Tom Walpole指出的那样，将poltergeist从1.6.0更新到1.7.0解决了我的大部分问题，但我仍需要调整一下以完全解决我的问题。我所做的是创建一个js文件来保存polyfill并编辑我的spec_helper.rb并告诉恶作剧者使用选项extensions并包含polyfill.js，从而改变来自

的代码

options = { js_errors: false }
  Capybara.register_driver :poltergeist do |app|
    Capybara::Poltergeist::Driver.new(app, options)
  end

到

options = { js_errors: false, extensions: ["spec/support/polyfill.js"] }
  Capybara.register_driver :poltergeist do |app|
    Capybara::Poltergeist::Driver.new(app, options)
  end

在rails之外使用poltergiest / capybara时触发Javascript
