| # This method returns the value from a factory that uses ngResource and a | |
| # method on that factory using Capybara's evaluate_script API. This method | |
| # has been tested with Poltergeist, a PhantomJS driver for Capybara | |
| # | |
| # This method uses window variables because a multi-line javascript function | |
| # in Poltergeist must be defined in an anonymous function. Therefore, the only | |
| # way I know of to get a closure outside of this context is by defining it | |
| # on the window. | |
