Ultimate solution for long running specs. It's not that rails are slow, or rspec is slow, or ruby is slow. It's your code that is slow and/or poorly designed. The solution to slow tests problem is not optimizing them once the are too slow - it's about not letting them get slugish in the first place.
# in your spec_helper.rb
RSpec.configure do |config|
config.around(:each) do |example|
timeout(0.2) { example.run }
end

Quick and a bit dirty solution for sync'ing all your DNS BIND files to route53
cli53 = '/home/ubuntu/.local/bin/cli53'
zones_on_aws = `#{cli53} list`.lines.select{|e| e =~ /Name/ }.map{|e| e.split(":").last.strip.sub(/\.$/, '') }
Dir.glob('zones/*.bind').each do |zone|
zone_name = File.basename(zone, '.bind')
unless zones_on_aws.include?(zone_name)
system("#{cli53} create #{zone_name}")
puts "#{zone_name} created."
end
abort("Can't sync #{zone_name}...") unless system("#{cli53} import #{zone_name} --file #{zone} --replace")

Any mailer inherited from this one will have random cat included as an attachment.
class KittenMailer < ActionMailer::Base
def mail *args
attachments['cat.jpeg'] = open("http://placekitten.com/#{rand(300)+300}/#{rand(300)+300}").read

Decent exposure decreases coupling in your controller and views. Draper helps you stop writing those messy helpers. I find forcing myself to decorate every object a good practice - we call this a 'decent decoration'
class ApplicationController < ActionController::Base
extend DecentDecorate
