RSpec - Register Example Group

worker_example_group.rb

module Support
  module WorkerExampleGroup
    include RSpec::Rails::RailsExampleGroup

    def self.included(base)
      base.metadata[:type] = :worker
    end
  end
end

RSpec.configure do |config|
  config.include Support::WorkerExampleGroup, :type => :worker,
    :example_group => { :file_path => config.escaped_path(%w[spec workers]) }
end

I'm adding a spec/workers dir for specific worker specs, which are mainly supposed to deal with background jobs, and I want to be able to include some shared helpers to them using config.include Support::MyHelpers, type: :worker. I based this code on rspec-rails example groups.
