How to test cookies with Rspec and Capybara in a feature test?

Question

I am using Rails 4.2 now.

My test file looks like:

# spec/features/my_spec.rb
require 'spec_helper'
feature 'MyFeature', type: :feature do
  describe 'MyPage' do
    it 'Saved the cookie' do
      visit my_path
      expect(response.cookies[:my_cookie]).to eq('some_value')
    end
  end
end

In the controller, I set a cookie as: cookies[:my_cookie] = 'some_value' , so in the spec file, I will test if the cookie has been saved after access the special path as above, but failed. The response is only used in the controller, but how to test cookies in this case?
