rspec --drb not working on RSpec with Spork

Question

After completing Michael Hartl's excellent Rails Tutorial, I decided to try to get Autotest and Spork going to speed up my tests. Everything seemed to install correctly, but when I came to the final hurdle (running rspec with the --drb flag) I'm getting the following error:

$ rspec --drb spec/

The tests work perfectly if I just enter $ rspec spec/ but are, of course, very slow. So it seems the problem might be with something I've done in relation to Spork. I followed the instructions at http://ruby.railstutorial.org/chapters/static-pages?version=3.0#sec:spork (using v3.0 instead of v3.2 as that's what I started with).

Please note that I'm running Cygwin on Windows, which means I'm on Ruby v1.8.7 instead of 1.9.2+. I don't know whether this would make a difference.

Any thoughts on how to get Spork going (Autotest seems to be fine) would be very much appreciated.

Thanks in advance!

PS My spec/spec_helper.rb looks like this:

require 'rubygems'
require 'spork'

Spork.prefork do
  # Loading more in this block will cause your tests to run faster. However,
  # if you change any configuration or code from libraries loaded here, you'll
  # need to restart spork for it take effect.
  # This file is copied to spec/ when you run 'rails generate rspec:install'
  ENV["RAILS_ENV"] ||= 'test'
  require File.expand_path("../../config/environment", __FILE__)
  require 'rspec/rails'
  require 'rspec/autorun'

  # Requires supporting ruby files with custom matchers and macros, etc,
  # in spec/support/ and its subdirectories.
  Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}

  RSpec.configure do |config|
    # ## Mock Framework
    #
    # If you prefer to use mocha, flexmock or RR, uncomment the appropriate line:
    #
    # config.mock_with :mocha
    # config.mock_with :flexmock
    # config.mock_with :rr

    # Remove this line if you're not using ActiveRecord or ActiveRecord fixtures
    config.fixture_path = "#{::Rails.root}/spec/fixtures"

    # If you're not using ActiveRecord, or you'd prefer not to run each of your
    # examples within a transaction, remove the following line or assign false
    # instead of true.
    config.use_transactional_fixtures = true

    # If true, the base class of anonymous controllers will be inferred
    # automatically. This will be the default behavior in future versions of
    # rspec-rails.
    config.infer_base_class_for_anonymous_controllers = false
end

Spork.each_run do
  # This code will be run each time you run your specs.

end

  def test_sign_in(user)
    controller.current_user = user
  end
end

Edit 2: I changed the ends in the spec_helper.rb file. I don't think that I had one extra, as was suggested, but I think they were in the wrong place, due to poor indenting on my part. The resulting file (with all the comments removed) looks like this:

require 'rubygems'
require 'spork'

Spork.prefork do
  ENV["RAILS_ENV"] ||= 'test'
  require File.expand_path("../../config/environment", __FILE__)
  require 'rspec/rails'
  require 'rspec/autorun'

  Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}

  RSpec.configure do |config|

    config.mock_with :rspec

    config.fixture_path = "#{::Rails.root}/spec/fixtures"

    config.use_transactional_fixtures = true

    config.infer_base_class_for_anonymous_controllers = false
  end
end

Spork.each_run do
end

def test_sign_in(user)
  controller.current_user = user
end

The error message is the still the same. Tomorrow, if I get a chance, I'll try to uninstall Ruby v1.8.7 and install v1.9.2 or 3, for want of any other ideas. Thanks very much for all the help that's been offered so far!

It looks like there is an extra unnecessary `end` in your `spec_helper`. Try taking it out and see if it helps. — nmott, Aug 16 '12 at 13:33

You're using an older version of Spork. You should try upgrading to v0.9.2 to see if that helps.

I know i kept forgetting bundle exec rspec . --drb after running spork in another tab. This got rid of any weird warnings for me. Maybe this is for google.

See lx00st's answer to spork 0.9.2 and rspec 3.0.0 = uninitialized constant RSpec::Core::CommandLine (NameError), quoting:

The reason is that RSpec::Core::CommandLine was removed in Rspec3 https://github.com/rspec/rspec-core/blob/master/Changelog.md

Merge RSpec::Core::CommandLine (never formally declared public) into RSpec::Core::Runner. (Myron Marston)

But spork depends on this code.

There is already an issue on spork's github and a solution can be found in a following spork's fork:

https://github.com/codecarson/spork/commit/38c79dcedb246daacbadb9f18d09f50cc837de51#diff-937afaa19ccfee172d722a05112a7c6fL6

In general - replace

::RSpec::Core::CommandLine.new(argv).run(stderr, stdout)

with

::RSpec::Core::Runner.run(argv,stderr, stdout)

in the soprks source code

It worked fine for me (thouhg I suspect a spork gem update might erase the source code fix). I just replaced the content 'spork/test_framework/rspec.rb' with the proposed content from github:

require 'rspec/core/version'

class Spork::TestFramework::RSpec < Spork::TestFramework
  DEFAULT_PORT = 8989
  HELPER_FILE = File.join(Dir.pwd, "spec/spec_helper.rb")

  def run_tests(argv, stderr, stdout)
    if rspec1?
      ::Spec::Runner::CommandLine.run(
        ::Spec::Runner::OptionParser.parse(argv, stderr, stdout)
      )
    elsif rspec3?
      options = ::RSpec::Core::ConfigurationOptions.new(argv)
      ::RSpec::Core::Runner.new(options).run(stderr, stdout)
    else
      ::RSpec::Core::CommandLine.new(argv).run(stderr, stdout)
    end
  end

  def rspec3?
    return false if !defined?(::RSpec::Core::Version::STRING)
    ::RSpec::Core::Version::STRING =~ /^3\./
  end

  def rspec1?
    defined?(Spec) && !defined?(RSpec)
  end
end

Thanks for the feedback @Athimannil, hope the answer is in better shape now. — ratiaris, Aug 11 '14 at 22:53
@RoryMcCrossan, got your hint. Note that I couldn't comment the initial question (not enough rep). — ratiaris, Aug 11 '14 at 22:55
