Spec Matcher for Rails and Rspec1 to ensure that a route does not route to a specific path

not_route_to.rb

# Sometimes in your app you may have a global route that will catch everything
# So it's not possible to use should_not be_routable or should_not route_to
# In this case you can use should not_route_to.
# Example:
# {:get => '/users/123/upgrade'}.should not_route_to(:controller => "users", :action => "upgrade", :user_id => "123")
