You are my hero!

Adding address stuff to @iloveitaly 's answer. This stuff still works as of late(ish) 2017.

    within_frame 'stripe_checkout_app' do
      find_field('Name').send_keys 'Some Person'
      find_field('Street').send_keys '123 Sunshine Pl.'
      find_field('City').send_keys 'Seattle'
      find_field('ZIP Code').send_keys '98112'
      find('button[type="submit"]').click

      find_field('Card number').send_keys '4242424242424242'
      find_field('MM / YY').send_keys "01#{DateTime.now.year + 1}"
      find_field('CVC').send_keys '123'
      find('button[type="submit"]').click
    end

for v3 (was able to find iframe only by position)

def fill_stripe(card, cvc, exp)
  iframes = all('iframe')
  card_iframe = iframes[0]
  cvc_iframe = iframes[1]
  exp_iframe = iframes[2]

  within_frame card_iframe do
    card.chars.each do |piece|
      find_field('cardnumber').send_keys(piece)
    end
  end

  within_frame cvc_iframe do
    cvc.chars.each do |piece|
      find_field('cvc').send_keys(piece)
    end
  end

  within_frame exp_iframe do
    exp.chars.each do |piece|
      find_field('exp-date').send_keys(piece)
    end
  end
end

Modified to work with Stripe Card Element:

  def fill_stripe_element(card,exp, cvc, postal='')
    card_iframe = all('iframe')[0]

    within_frame card_iframe do
      card.chars.each do |piece|
        find_field('cardnumber').send_keys(piece)
      end

      exp.chars.each do |piece|
        find_field('exp-date').send_keys(piece)
      end

      cvc.chars.each do |piece|
        find_field('cvc').send_keys(piece)
      end

     
      postal.chars.each do |piece|
        find_field('postal').send_keys(piece)
      end
    end
  end

Thanks @bhbryant!

Is this still working for you ? It's not working for me anymore... This is what I'm seeing

• Stripe DOES in fact initialize an iframe; without Stripe on the page, no iframe is found
• However, with Stripe and within that iframe, if I search for a generic input element, it defaults to an input I had put on the page

It's as if Stripe's iframe is "deflecting" to my regular view...

I added some helpers for Stripe SCA in case anyone needs that: https://gorails.com/blog/fill-in-stripe-elements-js-for-sca-3d-secure-2-and-capybara

Was wondering if there was any update to this for Stripe's Payment Element? Have been struggling to get this to work with the new way. Oddly, I can get it to work within a pry, but not when it runs by itself.
