How to mock JSONP call in rspec request specification with capybara?

I am working on integrating my rails application with Recurly.js.

Before I accessed my server server, I was able to complete all the integration with an excellent VCR stone ( https://github.com/myronmarston/vcr ), but Recurly.js makes a direct request to the service from javascript code using JSONP.

Question: how to mock these jsonp calls in an integration test?

I am currently using the rspec + capybara + phantomjs driver ( https://github.com/jonleighton/poltergeist )

, , - javascript . Poltergeist gem javascript , , Recurly.js :

# The original 'save' function performs JSONP request to Recurly.
# A token is borrowed during the real API interaction.
page.driver.execute_script("""
  Recurly.Subscription.save = function (options) {
    Recurly.postResult('/subscription', { token: 'afc58c4895354255a422cc0405a045b0' }, options);
  }
""")
