#with_routing ⇒ Object

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
