- Know Ruby First: http://www.poodr.info/ (quick Ruby OO read)
- Rails: http://ruby.railstutorial.org/ruby-on-rails-tutorial-book (don't just read it, DO IT, twice)
- Rspec: https://leanpub.com/everydayrailsrspec (Rspec is used in the tutorial, but other aspects are covered here)
- use Rspec rather than default TestUnit
rails new foo --skip-test-unit
gem "rspec-rails", "~> 2.12.2"
gem "factory_girl_rails", "~> 4.2.0"
(we also standardize on using Factory Girl)
