Poltergeist PhantomJSのドライバ

https://github.com/jonleighton/poltergeist

Rspecにcapybara, poltergeistを組み込み
vi spec/spec_helper.rb

require 'capybara/rspec'
require 'capybara/poltergeist'
Capybara.register_driver :rack_test do |app|
  Capybara::Poltergeist::Driver.new(app, :js_errors => false,
                                         :inspector => true,
                                         :phantomjs_options => ['--ignore-ssl-errors=yes'])
end

# Capybara.javascript_driver = :poltergeist
#Capybara.javascript_driver = :poltergeist_debug
Capybara.javascript_driver = :rack_test

Rspecのタスクを追加
vi Rakefile
require 'rspec/core/rake_task'

RSpec::Core::RakeTask.new(:spec)

task :default => :spec
