I am having a difficult time testing Stripe's Checkout.js product with Capybara. The problem is Stripe has some tricky client side validation that fools Capybara's javascript driver, so when I tell Capybara to fill in a field, like this:
fill_in "card_number", with: "4242424242424242"
Stripe field only fills up oly the first three digits then it automatically puts a space after those digits, and that breaks Capybara badly.
How can I fix this?
