    Metadata details:
    filename: integration_test_helper.rb
    path of file: ./repos/jekyll_picture_tag/test/integration
    
    the code of the file until where you have to start completion: require 'test_helper'
# Stubs and helpers for end-to-end tests
module IntegrationTestHelper
  include PictureTag
  include TestHelper

  attr_reader :stdout, :stderr

  def setup
    stub_liquid
  end

  # Parsed by Nokogiri, for easier a
    
  def tested_base(params = 'rms.jpg')
    output = ''
    @stdout, @stderr = capture_io do
      output = PictureTag::Picture
               .send(:new, 'picture', params, TokenStub.new(true, 'some stub'))
               .render(context)
    end

    output
  end
