Usage:

if you use caches_page

: Controller

class ProductsController < ActionController::Base
	caches_page :index  
	def index
		# something
	end
end

: RSpec

describe "get 'index'" do
	it "should cache the page" do
		lambda { get :index }.should cache_page('/products') # this is page url
	end
end

if you use caches_action

Maybe contains bugs

: Controller

class ProductsController < ActionController::Base
  caches_action :index
  def index
    # something
  end
end

: RSpec

describe "get 'index'" do
	it "should cache the action" do
		lambda { get :index }.should cache_action(:index)
	end
end

if you use fragment

: View

<%= cache 'my_cache' do %>
	<p>my_cache</p>
<% end %>

: RSpec

describe "get 'index'" do
	it "should fragment cache" do
		lambda { get :index }.should cache_fragment('views/my_cache')
	end
end
