Subject: Re: Use of capybara outside of any application

Well, including module in module is a bit tricky. I think what you want 
to do here is an extend, not an include.

include will put methods for instances of the class. Module's instances 
don't exist, I don't think that's what you want to do.

On the other hand, extend will add methods in the singleton class of the 
class (or here, the module) so that methods are accessible by the class 
itself (or here, the module itself). So I guess you need to do this 
instead :

module JustTestIt
  extend Capybara::DSL
  def self.run
    visit '/'
  end
end

Hope it helped !
