this is very broken and i'm not sure why

run-test.js

#!/usr/bin/env node

    spawn = require('child_process').spawn,
    http = require('http');

var PORT = 8080;
var PROXY_PORT = 8090;

var test = process.argv[2];

if (!test) {
  return console.error('Need test to run');
}

console.log('Running test ' + test);

var proxyserver = http.createServer(function (req, res) {
  var self = this,
      outgoing = {},
      reverseProxy;

  outgoing.host    = 'localhost';
  outgoing.port    = PORT;
  outgoing.method  = req.method;
  outgoing.path    = req.url;
  outgoing.headers = req.headers;

  reverseProxy = http.request(outgoing, function (response) {
    res.writeHead(response.statusCode, response.headers);
    response.pipe(res);
  });

  req.pipe(reverseProxy);
});
proxyserver.listen(PROXY_PORT);

proxyserver.on('listening', function () {
  console.log('Proxy server listening on ' + PROXY_PORT);
  var testProcess = spawn(process.argv[0], [ process.argv[2] ]);
  testProcess.stdout.pipe(process.stdout);
  testProcess.stderr.pipe(process.stderr);
  testProcess.on('exit', process.exit);
});
