I discovered today that I had no idea of how to fake an xhr request in an Rspec controller test. I need this cause some of my layout strategy behaves on the request.xhr? method. As expected Rspec solved the issue in a cool and elegant way.

	# normal request
	get :show, id: 1  
	# exactly the same request, This time fake to be an xhr call. request.xhr? will be true
	xhr :get, :show, id: 1
