This looks wrong, you only call checkready once, and its not on .listen

```
function startServers(done) {
  http_server.createServer().listen(HTTP_PORT, function() {
    cors_proxy.options = {target: couchHost || COUCH_HOST};
    http_proxy.createServer(cors_proxy).listen(CORS_PORT, function() {
      var testRoot = 'http://127.0.0.1:' + HTTP_PORT;
      var query = '';
      Object.keys(queryParams).forEach(function (key) {
        query += (query ? '&' : '?');
        query += key + '=' + encodeURIComponent(queryParams[key]);
      });
      console.log('Integration tests: ' + testRoot +
                  '/tests/test.html' + query);
      console.log('Performance tests: ' + testRoot +
                  '/tests/performance/test.html');
    });
  });
}
```

is the off the top of my head one
