failing example of testing will_paginate with a stub

testing_will_paginate.rb

require 'will_paginate/array'

describe "recurrences/index" do
  let(:recurrences) do [
    FactoryGirl.build(:recurrence, scheduled_to: "2012-07-05"),
    FactoryGirl.build(:recurrence, scheduled_to: "2012-07-12"),
    FactoryGirl.build(:recurrence, scheduled_to: "2012-07-19")
  ]
  end

  it "should have a pagination bar" do
    assign(:recurrences, recurrences)
    Recurrence.stub(:paginate).with(page: "1").and_return(recurrences.paginate(per_page: 2))
    render

    expect(rendered).to have_selector('div.pagination') 
  end
end

But this leads to an error: 

ActionView::Template::Error:
undefined method `total_pages' for #<Array:0xa18ba8c>
