class Spork::Server

(This was originally based off of spec_server.rb from rspec-rails (David Chelimsky), which was based on Florian Weber’s TDDMate)
An abstract class that is implemented to create a server

def self.run(options = {}) 

def self.run(options = {})
  new(options).listen
end

def abort 

def abort
  run_strategy.abort
end

def initialize(options = {}) 

def initialize(options = {})
  @run_strategy = options[:run_strategy]
  @port = options[:port]
end

def listen

Sets up signals and starts the DRb service. If it's successful, it doesn't return. Not ever. You don't need to override this. 
def listen
  @run_strategy.assert_ready!
  trap("SIGINT") { sig_int_received }
  trap("SIGTERM") { abort; exit!(0) }
  trap("USR2") { abort; restart } if Signal.list.has_key?("USR2")
  @drb_service = DRb.start_service("druby://127.0.0.1:#{port}", self)
  Spork.each_run { @drb_service.stop_service } if @run_strategy.class == Spork::RunStrategy::Forking
  stderr.puts "Spork is ready and listening on #{port}!"
  stderr.flush
  DRb.thread.join
end

def restart 

def restart
  stderr.puts "restarting"
  stderr.flush
  config       = ::Config::CONFIG
  ruby         = File::join(config['bindir'], config['ruby_install_name']) + config['EXEEXT']
  command_line = [ruby, $0, ARGV].flatten.join(' ')
  exec(command_line)
end

def run(argv, stderr, stdout)

When implementing a test server, don't override this method: override run_tests instead.

spec_server.run(options.argv, $stderr, $stdout)
spec_server = DRbObject.new_with_uri("druby://127.0.0.1:8989")
# see http://redmine.ruby-lang.org/issues/show/496 to see why localhost:0 is used.
DRb.start_service("druby://localhost:0") # this allows Ruby to do some magical stuff so you can pass an output stream over DRb.

This is the public facing method that is served up by DRb. To use it from the client side (in a testing framework): 
def run(argv, stderr, stdout)
  puts "Running tests with args #{argv.inspect}..."
  result = run_strategy.run(argv, stderr, stdout)
  puts "Done.\n\n"
  result
end

def sig_int_received 

def sig_int_received
  stdout.puts "\n"
  abort
  if run_strategy.running?
    stderr.puts "Running tests stopped.  Press CTRL-C again to stop the server."
    stderr.flush
  else
    exit!(0)
  end
end
