How to set locale default_url_options for functional tests (Rails)

Question

In my application_controller, I have the following set to include the locale with all paths generated by url_for:

  def default_url_options(options={})
    {         


        

Answer 1

For Rails 5, I found this simple solution In test_helper.rb based on action_dispatch/testing/integration.rb

module ActionDispatch::Integration
  class Session
    def default_url_options
      { locale: I18n.locale }
    end
  end
end
