I'm trying to write a test for a modification I've done on link_to helper. The problem is that my patch is relying on url_for behaviour defined in link_to helper.
In url_helper_test.rb test file url_for is overwrited for testing convinience.
So my question is how can I do to test my modification using the real url_for method (the one in url_helper.rb). Is there a way to load it from the inside of my test or something like this?
Thank you in advance.
