ruby-on-rails-3 - Capybara 无法从 Stripe 中找到表单字段？

我正在学习 Ruby on Rails，我正在开发一个使用 Stripe 创建高级帐户的应用程序。此外，我正在使用 Rspec 和 Capybara 进行集成测试。

require 'spec_helper'

feature "user upgrade account to a premium plan" do
 scenario "user upgrade account", :js => true do
  user = FactoryGirl.create :user
  visit new_user_session_path
  fill_in 'Email', :with => user.email
  fill_in 'Password', :with => user.password
  click_button 'Sign in'

  visit new_charge_path
  click_button "Pay with Card"

  fill_in 'Email', :with => '[email protected]'
  fill_in "Card number", :with => "4242424242424242"
  fill_in 'CVC', :with => '123'
  fill_in 'MM/YY', :with => '11/14'

  click_button 'Pay $5.00'

 end

我运行测试并收到一条错误消息，内容为:

 Failure/Error: fill_in "Card number", :with => "4242424242424242"
 Capybara::ElementNotFound:
   Unable to find field "Card number"

任何人都知道，可能是什么问题？
谢谢。

最佳答案

根据您集成 Stripe 的方式，它可能会在 iframe 中呈现表单。如果是这种情况，您需要使用 Capybara.within_frame 将 Action 定位到正确的帧:

scenario "user upgrade account", :js => true do
  user = FactoryGirl.create :user
  visit new_user_session_path
  fill_in 'Email', :with => user.email
  fill_in 'Password', :with => user.password
  click_button 'Sign in'

  visit new_charge_path
  click_button "Pay with Card"

  Capybara.within_frame 'stripe_checkout_app' do
    fill_in 'Email', :with => '[email protected]'
    fill_in "Card number", :with => "4242424242424242"
    fill_in 'CVC', :with => '123'
    fill_in 'MM/YY', :with => '11/14'

    click_button 'Pay $5.00'
  end
end
