# simple HTTPServer: 
# useful to test your pages/api calls!

class HTTPServer
  def initialize(port, body)
    require 'socket'
    
    @server = Thread.new do
      server = TCPServer.open port
      loop do                       
        client = server.accept      
        content_type = "text/html"
        client.puts "HTTP/1.1 200/OK\nContent-type:#{content_type}\n\n#{body}\n\n"
        client.close                
      end

  def kill!
    @server.kill
  end
  
  alias :kill :kill!

# vanilla ruby and rspec example, uncomment and run:

# srv = HTTPServer.new 2000, "hello world"
# require 'net/http'
# uri = URI.parse "http://localhost:2000"
# page = Net::HTTP.get_response uri
# puts "page should =~ /hello world/ (uncomment the line below)"
# # page.should =~ /hello world/
# srv.kill



# full fledged spec, adding nokogiri:

# remember to remove the "require 'spec_helper'" line for faster load time

# require 'net/http'
#
# class YourService
#   def self.get
#     uri = URI.parse "http://localhost:2000"
#     Net::HTTP.get_response(uri).body
#   end
# end
# 
# describe "Something" do
#   before :all do
#     @srv = HTTPServer.new 2000, "<div>hello world</div>"
#   end
#   
#   after :all do
#     @srv.kill
#   end
#   
#   it "should greet" do
#     page = YourService.get
#     page.should =~ /hello world/
#   end
#   
#   it "should greet" do
#     require 'nokogiri'
#     page = Nokogiri::HTML YourService.get
#     page.css("div").inner_text.should == "hello world"
#   end
# end
