module ScriptSpecHelper
  # Run the script defined in a spec's let(:script)
  # It rescues from the SystemExit exception that all scripts raise
  # once they are finished (this is how the runner is setup)

  # Yield to the given block before the script is run
  # This is useful for setup code
  # or if script is an instance, you can write some expectations or stubs
  # Example:
  #
  #   require 'spec_helper'
  #   module Process
  #     describe MyCoolScript do
  #       let(:script) { Process::MyCoolScript.new }
  #       it "should should find five downloads" do
  #         run_script do
  #           script.should_receive(:downloads).and_return(5)
  #         end
  #       end
  #     end
  #   end
