Hey James - had your mail queued to reply to for quite a while!

Thanks for posting, very interesting. I've also been GUI testing through AppleScript, in my case with Cucumber. 

Scenario: Convert a single jpeg file
	When I run the app
	And I open the file "testdata/testcard.jpg"
	Then the front window title should be "testcard.jpg"
	When I wait for window with title "testcard.pdf"
	And I click "Save"
	Then the file "testdata/testcard.pdf" should exist

This is backed by feature-support.rb

When /^I run the app$/ do
  @app = run_app
end

When /^I open the file "([^\"]*)"$/ do |file|
  @app.open file
end

When /^I (?:press|click) "([^\"]*)"$/ do |button_name|
  @app.button(button_name).click
end

and a driver like

include Appscript

def run_app files = []
	VelOCRaptor.new 'VelOCRaptor', Dir.getwd + '/build/release', files
end

class VelOCRaptor

	def initialize app_name, path, files, run = true
		@app_name = app_name
		app_path = File.join(path, "#{app_name}.app")
		if run
			command = "open -W -a #{app_path}"
			files.each { |file| command << %[ "#{file}"] }
			IO.popen command
			sleep 2
		end
		@events = app 'System Events'
		@process = @events.processes[@app_name]
		@app = app app_path
	end

	def open file
		@app.open File.expand_path(file)
	end

etc.

As is usual with GUI tests I'm still fighting occasional failures due to not waiting for things to happen. I'd be very interested to compare more of our drivers if you'd like to contact me off list.
