  caches_page :index  
 
  def index
    # something
  end
end

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
