    Metadata details:
    filename: content_system_test.rb
    path of file: ./repos/workarea/storefront/test/system/workarea/storefront
    
    the code of the file until where you have to start completion: require 'test_helper'

module Workarea
  module Storefront
    class ContentSystemTest < Workarea::SystemTest
      include BreakpointHelpers
      setup :set_content_page

      def set_content_page
        @content_page = cr
    
      def test_responsively_visible_content_blocks
        Content.for(@content_page).blocks.create!(
          type: :html,
          data: { html: 'foo bar', barf: 'no' },
          hidden_breakpoints: ['medium']
        )

        visit storefront.page_path(@content_page)

        resize_window_to('small')
        assert(page.has_content?('foo bar'))

        resize_window_to('medium')
        refute_text('foo bar')

        resize_window_to('wide')
        assert(page.has_content?('foo bar'))
      end
