Rails 3, RSpec and Cucumber setup
This quick how-to runs through creating a new Rails 3 application with both RSpec and Cucumber for testing (rather than Test::Unit).
Rails 3 requires (the somewhat confusingly versioned) RSpec 2 and rspec-rails. Similarly, Cucumber uses cucumber-rails for bootstrapping your Rails app and provides generators for creating features.
Install RSpec 2
sudo gem install rspec-rails --preInstall Cucumber
sudo gem install cucumber-railsCreate a new Rails 3 application
Ensure you have the latest version of Rails 3 installed then
