Why startup and shutdown is not being called?

startup and shudown method is being called if it is inside the one class
only. But if i put that into module and include this module in another
class as shown below startup and shutdown method is not being called.
module BaseClass
  class << self
    def startup
      p "startup"
    end

    def shutdown
      p "shutdown"
    end
  end

  def setup
    puts "setup called"
  end

  def teardown
    puts "teardown called"
  end

  def cleanup
    p "cleanup"
  end
end

DemoTest1.rb

require 'rubygems'
gem 'test-unit'
require 'test/unit'
require "BaseClass"

class DemoTest1 < Test::Unit::TestCase
include BaseClass

  def test_third()
    puts "third"
  end
end

now if i execute the DemoTest1.rb I am getting below output
Started
setup called
third
"cleanup"
teardown called

startup and shutdown method is not being called. And i don't know why??
any idea guys ???

Modules don't work that way. You're defining startup and shutdown on
BaseClass' singleton class, which is not pointed to by DemoTest1's singleton
class. You should ether define those methods in another module and then
extend DemoTest1, like this:

module BaseClassClassMethods
  def startup
    p "startup"
  end

  def shutdown
    p "shutdown"
  end
end

module BaseClassInstanceMethods
  def setup
    p "setup"
  end

  def teardown
    p "teardown"
  end

  def cleanup
    p "cleanup"
  end
end

require 'rubygems'
gem 'test-unit'
require 'test/unit'

class DemoTest1 < Test::Unit::TestCase
  include BaseClassInstanceMethods
  extend BaseClassClassMethods

  def test_third()
    puts "third"
  end
end

Or you could hook into the inclusion like this:

module BaseClass
  def self.included(klass)
    klass.instance_eval do
      def startup
        p "startup"
      end

      def shutdown
        p "shutdown"
      end
    end
  end

  def setup
    p "setup"
  end

  def teardown
    p "teardown"
  end

  def cleanup
    p "cleanup"
  end
end

require 'rubygems'
gem 'test-unit'
require 'test/unit'

class DemoTest1 < Test::Unit::TestCase
  include BaseClass

  def test_third()
    puts "third"
  end
end
