RSpec response.body is still empty even with config.render_views

In my spec_helper.rb file I have specifically set it to config.render_views but the response.body I get back is still empty. Here is my basic spec

describe  "#index" do
    it "should list all rooms" do
      get 'index'
      stub(Person).all
    end

    it "responds with 200 response code" do
      response.should be_ok
    end

    it "renders the index template" do
      pp response.body
      response.should render_template("people/index")
    end

  end

Is there anything else that could have shorted this behavior? It's fine when I go through the browser. I am on Rspec 2.5.0
