Why do I get "Undefined method ::new" in simple classes? - ruby

Question

I am writing an ATM-system-like socket/server solution. I would appreciate if someone could tell me what I'm missing. For some reason, I get the following error running my stub test suite:
# Running tests:
.E
Finished tests in 0.002411s, 829.4384 tests/s, 414.7192 assertions/s.
1) Error:
test_0001_connects_to_a_host_with_a_socket(AtmClient::connection):

My minispec file is:
require_relative '../spec_helper.rb'
require_relative '../../lib/AtmClient.rb'
require_relative 'SpoofServer.rb'
describe AtmClient do
it "can be created with no arguments" do
AtmClient.new.must_be_instance_of AtmClient
end
describe 'connection' do
it "connects to a host with a socket" do
spoof = SpoofServer.new.start
client = AtmClient.new.connect
spoof.any_incoming_connection?.must_be true
spoof.kill
end
end
end
My SpoofServer file is:
require 'socket'
class SpoofServer
def initialize
end
def start
#clients = []
#server = TCPServer.new 1234
#listener_thread = new Thread do
#clients.add #server.accept
end
end
def any_incoming_connection?
#clients.size > 0
end
def kill
#listener_thread.exit
#clients.each {|c| c.close}
end
end

Answer 1

As you can read in the trace of the calls stack:
NoMethodError: undefined method `new' for #<SpoofServer:...>
/.../spec/client/SpoofServer.rb:12:in `start'
The error is inside the start method defined in SpoofServer.rb, at line 12, the wrong line is:
#listener_thread = new Thread do
That should be:
#listener_thread = Thread.new do
As you have written it, what you are actually doing is to calling the new method passing the Thread class as argument. Since no new method is defined for instances of the SpoofServer class you get the NoMethodError exception.

Answer 2

In body of instance method SpoofServer#start, you can't call the class method SpoofServer.new by new.
