Not sure where this error is coming from but looking for help to isolate.

I'm trying to add spork (via spork-minitest) to my rails 3.2.3 project which is using minitest and guard. I've added spork-minitest to the gemfile, and generated a spork entry in the guardfile:

guard 'spork', cucumber: false, test_unit: false, minitest: true, :minitest_env => { 'RAILS_ENV' => 'test' } do
  watch('config/application.rb')
  watch('config/environment.rb')
  watch(%r{^config/environments/.+\.rb$})
  watch(%r{^config/initializers/.+\.rb$})
  watch('Gemfile')
  watch('Gemfile.lock')
  watch('test/test_helper.rb') { :minitest }
end

I moved all of the code in my test_helper into the Spork.prefork block:

require 'rubygems'
require 'spork'

Spork.prefork do
  ENV["RAILS_ENV"] = "test"
  require File.expand_path('../../config/environment', __FILE__)
  require "rails/test_help"
  require "minitest/autorun"
  require "minitest/rails"
  require 'capybara/rails'
  class MiniTest::Rails::Spec
    include Mongoid::Matchers
    include Capybara::DSL
    before :each do
      # ensure a clean slate for each unit test
      Mongoid.master.collections.select {|c| c.name !~ /system/ }.each(&:drop)
    end
  end
end

Spork.each_run do
end

I can then run spork using and see that tests are much faster via time bundle exec rake test:models --drb (complains about --drb option, but it takes it anyway).

I then try to run the same process through guard via bundle exec guard. It starts properly, but errors when running the tests:

$ bundle exec guard
Guard uses Growl to send notifications.

Done.

I'm starting here because spork-minitest is deepest in the stack, and because I verified that guard works properly before attempting to integrate spork.

Unfortunately, this gem doesn't work with guard properly. Apparently it works now with guard-spork, since you don't get any errors on the start but guard-minitest is still broken. The issue is that spork-minitest doesn't support any options like -r or -e that the guard is passing.

I have found that it is too complex to fix that and decided to use a Guard MiniTest alternative for testing: Autotest (or ZenTest). Also, I start spork manually. If you still want to use Guard you can try out the original spork-testunit instead of spork-minitest. It is much more complex than mine but should work.

Thanks @semaperepelitsa ... I hadn't tried autotest before, I think I'll give it a spin. Wondering if you were able to get minitest/autotest to use spork? Can't quite figure out how to get the drb option passed in correctly.

There is a code snippet in the bottom of the readme.

Thanks, I missed that before. Did the trick. I also added something to .autotest to run spork if it's not already running. Very kludgy solution I'm sure, but in case anyone is interested (gist: https://gist.github.com/2667886)

require 'socket'
require 'timeout'

def is_port_open?(ip, port)
  begin
    Timeout::timeout(1) do
      begin
        s = TCPSocket.new(ip, port)
        s.close
        return false
      rescue Errno::ECONNREFUSED, Errno::EHOSTUNREACH
        return true
      end
    end
  rescue Timeout::Error
  end

  return true
end

if is_port_open?('localhost', 8988)
  pid = fork do
     `spork`
      exit
  end
  puts "waiting for spork to start"
  while is_port_open?('localhost', 8988) do sleep 0.1 end

end


require 'autotest/restart'
require 'autotest/growl'
require 'autotest/fsevent'
require 'turn/autorun'

Autotest.add_hook :initialize do |at|
  at.testlib = ".minitest"
end

Autotest.add_hook :all_good do |at|
  system "rake rcov_info"
end if ENV['RCOV']

class Autotest
  # run tests over drb server (spork)
  def make_test_cmd files_to_test
    if files_to_test.empty?
      "" # no tests to run
    else
      "testdrb #{files_to_test.keys.join(' ')}"
    end
  end
end

Very good! One note: you should use spawn "spork" instead of forking the ruby process and running the command after that.
