Rails.application.routes.default_url_options = { :host => 'example.com' }

view_paths = Rails.application.config.paths["app/views"]
action_view = ActionView::Base.new(view_paths).tap do |av|
  action_view.class_eval do
    include ApplicationHelper
    include Rails.application.routes.url_helpers
    include JobOffersHelper
  end

action_view.render partial: 'default/job_offer', locals: { job_offer: JobOffer.first }
