Spork

If you have used spork in the past, or need to run certain tasks after forking specifically in your test environment, this pattern will be of use to you.

prefork = lambda {
  # ...
}

each_run = lambda {
  # ...
}

if defined?(Zeus)
  prefork.call
  $each_run = each_run
  class << Zeus.plan
    def after_fork_with_test
      after_fork_without_test
      $each_run.call
    end
    alias_method_chain :after_fork, :test
  end
elsif ENV['spork'] || $0 =~ /\bspork$/
  require 'spork'
  Spork.prefork(&prefork)
  Spork.each_run(&each_run)
else
  prefork.call
  each_run.call
end
