What's this?

with_routing() public

A helper to make it easier to test different route configurations. This method temporarily replaces ActionController::Routing::Routes with a new RouteSet instance.

The new instance is yielded to the passed block. Typically the block will create some routes using map.draw { map.connect … }:

 with_routing do |set|
   set.draw do |map|
     map.connect ':controller/:action/:id'
       assert_equal(
         ['/content/10/show', {}],
         map.generate(:controller => 'content', :id => 10, :action => 'show')
     end
   end
 end
