title: rspec and recaptcha
body: <p>I'm building tests for a user sign-up page.  I'm about to add Recaptcha to the page, and I don't know how to account for it in rspec.  Specifically, I want my integration test to verify that a user can fill out the page, click on the button, and will be signed up.  But with Recaptcha on the page, how do I get Rspec to simulate entering a valid Recaptcha string?</p>
