Your problem, as I understand it, is that included is called in the
context of the class Test and not any of it's instances.

Try this (http://pastie.caboo.se/150269):

module Extras

 def initialize_with_extras
   initialize_without_extras #Do it!
   @tests[2] = 'ok too!'
 end

 def self.included( base )
   base.__send__( :alias_method, :initialize_without_extras, :initialize )
   base.__send__( :alias_method, :initialize, :initialize_with_extras )
 end

end

Output:

["ok!", "ok too!"]

It uses the "included" method in the module to amend the class and
setup the initialize alias chain that you need.

Hope this helps.

Regards,

Matt.
