Capybara无法从Stripe中找到表单字段？

Question

我正在学习Ruby on Rails，并且正在开发一个使用条纹创建高级帐户的应用程序。另外，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，指出：

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

所有人都知道，这可能是什么问题？谢谢。

Answer 1

取决于您如何集成Stripe，它可能正在iframe中呈现表单。在这种情况下，您需要使用Capybara.within_frame将操作定位到正确的帧：

Capybara.within_frame

Answer 2

尝试使用元素ID代替字段标签。

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

（是card_number和cvc输入字段的ID。）>

fill_in 'card_number', :with => '4242424242424242'
fill_in 'cvc', :with => '123'
我遇到了同样的问题，我使用了此解决方案，不确定这是否是一个好习惯，但是对我有用。
