1. Crie um novo arquivo em spec/support/

# spec/support/select_from_chosen.rb
module SelectFromChosen
  # select_from_chosen('Option', from: 'id_of_field')
  def select_from_chosen(item_text, options)
    field = find_field(options[:from], :visible => false)
    find("##{field[:id]}_chosen").click
    find("##{field[:id]}_chosen ul.chosen-results li", :text => item_text).click
  end
end

1. Inclua o módulo na configuração Rspec para recursos:

# spec/rails_helper.rb
