"wrong constant name" Error when using Turnip with Spork

Question

My Turnip test is working normally, but does not work when using spork.
I debugged with pry and I found that a missing User(class constant) causes the error.

What should I do to fix?

# working (good)
bundle exec rspec spec/acceptance/features/*

# not work (bad)
bundle exec rspec spec/acceptance/features/* --drb

Here is the error when I run with the --drb option.

Failure/Error: Give a user logged in:
NameError:
wrong constant name #<Module:0x007fd40a19c680>
# spec/acceptance/steps/user_steps.rb:8:in `block (2 levels) in <module:UserSteps>'
# spec/acceptance/steps/user_steps.rb:7:in `each'

This is my spec_helper.rb.

require 'rubygems'
require 'spork'
#uncomment the following line to use spork with the debugger
#require 'spork/ext/ruby-debug'

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

  # 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}
  Dir.glob("spec/**/*steps.rb") { |f| load f, true }

  WebMock.disable_net_connect!(:allow_localhost => true)

  Capybara.run_server = true
  Capybara.app_host = 'http://localhost'
  Capybara.server_port = 8000
  Capybara.default_selector = :css
  Capybara.javascript_driver = :webkit

  OmniAuth.config.test_mode = true

  RSpec.configure do |config|
    # ## Mock Framework
    config.mock_with :rr
    config.infer_base_class_for_anonymous_controllers = false
    config.order = "random"

    config.include FactoryGirl::Syntax::Methods
    config.include Capybara::DSL, turnip: true
    config.include Rails.application.routes.url_helpers

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

    config.before(:each) do
      DatabaseCleaner.start
    end

    config.after(:each) do
      DatabaseCleaner.clean
    end

    config.before(:each, js: true) do
      headless = Headless.new
      headless.start
    end
  end
end

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

end

This is user_steps.rb.

1.  require_relative 'helper_steps'
2. 
3.  module UserSteps
4.    include HelperSteps
5. 
6.    step 'users are registered :' do |table|
7.      table.hashes.each do |row_hash|
8.       create(:user, class_params_by_row_hash(User, row_hash))
9.    end
10.  end
11. end

I'm not sure why this problem occurs, but you can prevent it from happening. If you're wrapping your steps in modules, you don't need to pass the true wrap parameter to load. Change:

Dir.glob("spec/**/*steps.rb") { |f| load f, true }

to:

Dir.glob("spec/**/*steps.rb") { |f| load f }

This prevents this error for me.
