Graeme has been making a nuisance of himself on the Internet and in various 
open source communities since 1992 when he managed to blag a 9k6 modem from 
school. He didn't discover Ruby until late 2005 when he was frustrated with 
Zope (Python's only web framework at the time) and heard about this thing 
called Rails.

Graeme was so impressed with Rails (and Ruby) that he quit his day job and 
started his own company, Rubaidh, so he could work with it full time. Since 
then he's worked with a variety of companies – from tiny startups to 
household names – using Ruby to deliver reliable, usable, secure software.

This was a quick hack attempt to create a simple factory_girl-like thing for objects that weren't ActiveRecord-based at all, just plain ol' objects with attr_accessors.

Didn't work quickly enough to pursue, but I didn't want to throw it away either. :-)

Hash ordering test

This test passes on my system right now. (It might not on your system, but that's not important. Change the assert_equal so that it does.)

Now uncomment the @other_hash declaration. It (probably) fails.

That makes the hashing algorithm in Ruby dependent upon the code that runs before it. Which, when you accidentally depend upon the order of keys in a hash, makes for a lot of confusion later on when it no longer works!

The particular example involved verifying that a model accepted nested attributes. We were doing something along the lines of:

#!/usr/bin/env ruby
require File.dirname(__FILE__) + '/../config/boot'
require "#{RAILS_ROOT}/config/environment"

crud_actions = [ "index", "show", "new", "edit", "create", "update", "destroy" ]
# Force all the controllers in the application to be loaded.
Dir['app/controllers/**/*_controller.rb'].each { |f| load f }

all_controllers = ObjectSpace.each_object.select do |object|
  object.class == Class && object.name =~ /Controller$/
