development and test gems
----------------------------------------------

group :development, :test do
  gem 'sqlite3'
  gem 'rspec-rails'
  gem "capybara"

RSpec.configure do |config|

  config.before(:suite) do
    DatabaseCleaner.clean_with(:truncation)
  end

  config.before(:each) do
    DatabaseCleaner.strategy = :transaction
  end

  config.before(:each, :js => true) do
    DatabaseCleaner.strategy = :truncation
  end

  config.before(:each) do

require 'capybara/rspec'
require 'capybara/rails'

The run 'rails generate rspec:install' to create the directory
------------------------------------

To test a javascript element, you need to add :js => true before the do in the it block

it "should be able enter email and generate badge code", :js => true do

Setting up poltergeist -- supposedly - still doesn't work for me

group :development, :test do
gem 'sqlite3'
gem 'rspec-rails'
gem 'capybara'
gem 'shoulda-matchers'
gem 'launchy'
gem 'poltergeist'

end

Spec Helper

---

require 'capybara/rspec'

require 'capybara/rails'

The run 'rails generate rspec:install' to create the directory

In the spec helper -
require 'capybara/poltergeist'
Capybara.javascript_driver = :poltergeist
