Testing individual nodes launched by naught using supertest
I think you should write more code before submitting, the fun part to review is the code that you wrote after the prototype ;)

From a quick once over:


JsHint finds no fault except for some mixed use of tabs and space
Consider 'use strict', it can save lives
Consider something better than console.log, especially if you are going to use this code for performance testing
Use lowerCamelCase consistently: testport -> testPort
