Autotest config

What seems to be working for me is the following:

group :development, :test do
  gem 'rspec-rails'
  gem 'webrat'
  gem 'autotest'
  gem 'autotest-growl'
  gem 'autotest-rails'
  gem 'cucumber-rails'
  gem 'factory_girl_rails'
  gem 'mocha'
  gem 'launchy'
end

And in ~/:autotest

require 'autotest/growl'
Autotest::Growl::clear_terminal = false
Autotest.add_hook :initialize do |at|
  at.find_directories = ['./features', './spec', './app', './lib']
end

The hook selects directories to watch. The default setup caused autotest to run features continuously
