Shortcut for ActionController::TestUploadedFile.new(ActionController::TestCase.fixture_path + path, type):
  post :change_avatar, :avatar => fixture_file_upload('/files/spongebob.png', 'image/png')
To upload binary files on Windows, pass :binary as the last parameter. This will not affect other platforms:
  post :change_avatar, :avatar => fixture_file_upload('/files/spongebob.png', 'image/png', :binary)
        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
