FakeS3 automation for rspec

aws.yml

test:
  s3_endpoint: localhost
  s3_force_path_style: true
  s3_port: 10001
  use_ssl: false
  access_key_id: key
  secret_access_key: secret

fakes3_server.rb

class FakeS3Server
  require 'fakes3'

  def initialize(pid)
    @pid = pid
  end

  def self.up
    pid = spawn("bundle exec fakes3 --port 10001 --root #{Rails.root.join('fakes3')}")
    @@instance = FakeS3Server.new(pid)
    return @@instance
  end

  def self.down
    @@instance.down if defined? @@instance
  end

  def down
    if @pid
      Process.kill("SIGINT", @pid)
      Process.waitpid2(@pid)
      @pid = nil
    end
  end

end

Gemfile

# Make sure you have the fakes3 gem installed
group :test do
  gem 'fakes3'
end

spec_helper.rb

# Require support/fakes3 which has the FakeS3Server class, you can save the file anywhere you want
# Call up before and down after
require 'support/fakes3_server'
RSpec.configure do |config|
  config.before(:suite) { FakeS3Server.up }
  config.after(:suite) { FakeS3Server.down }
end

You'll also need to create a fakes3 folder in your project root. Anything you save or get will be in there.
