How to use request helpers outside of controller tests?

I'd like to use the request helpers
) outside of my RSpec controller tests (in other RSpec tests), but I
don't know how to include and use them there.

Best regards,

I just solved the problem by including the below code in my acceptance
helper. If you are not Steak then just simply put it in spec helper or
require it from somewhere else. post and xhr methods are now available
in that spec regardless in what spec it is or in what directory you

The code is derived from RSpec::Rails::RequestExampleGroup

RSpec::Core::ExampleGroup.class_eval do
  include ActiveSupport::Concern
  include ActionDispatch::Integration::Runner
  include RSpec::Rails::BrowserSimulators

  def app

  def last_response
