When API testing slows you down: record and replay HTTP responses like a boss

# NOTES:
# All requests using a hostname are routed to 127.0.0.1
# Port 3001 has a live server, see below for paths and responses
# Port 3002 has no server, connections will be refused


DNS = require("dns")
Express = require("express")
Replay = require("../lib/replay")


# Directory to load fixtures from.
Replay.fixtures = "#{__dirname}/fixtures"


# Redirect HTTP requests to pass-through domain
original_lookup = DNS.lookup
DNS.lookup = (domain, callback)->
  if domain == "pass-through"
    callback null, "127.0.0.1", 4
  else
    original_lookup domain, callback

# Serve pages from localhost.
server = Express.createServer()
server.use Express.bodyParser()
# Success page.
server.get "/", (req, res)->
  res.send "Success!"
# Not found
server.get "/404", (req, res)->
  res.send 404, "Not found"
# Internal error
server.get "/500", (req, res)->
  res.send 500, "Boom!"


# Setup environment for running tests.
setup = (callback)->
  server.listen 3001, callback
  return

    return
  server.on "listening", callback
