mocksocket

---

tiny class providing an IO/TCPSocket mock, full duplex and everything. mainly useful for testing TCPSocket applications.

>> require ‘mocksocket’ >> client, server = MockSocket.pipe #=> [M, M] >> client.puts “hello, I’m a client!” >> server.gets #=> “hello, I’m a client!n” >> server.puts “welcome, client.” >> client.gets #=> “welcome, client.n”

it uses Timeout, so instead of stalled tests, you get some timeout exception, if you’re trying to read from an empty buffer.

methods implemented: #puts, #print, #gets, #eof? and the ever-handy #empty?

as well there’s tiny test extensions for test/unit:

require 'mocksocket/test'

module Test::Unit::Assertions
  include MockSocket::Assertions
end

def setup
  @c, @s = MockSocket.pipe
end

def test_empty_buffer
  assert_empty_buffer @c
end

.. and bacon:

require 'mocksocket/bacon'

describe "awesome" do
  before { @c, @s = MockSocket.pipe }
end

should "be empty" do
  @c.should.be empty_buffer
end
