A Data Driven Test library for node.js

I was trying to get ddt module ("http://ift.tt/18k84V1") working on my web app I have tried the example they gave on their npm page. what I am looking for is to implement this on my web service. the web service returns JSON object as an API so can I use the ddt module to test if the web service is functioning properly?

if so can you please give me sample how I can do that on express framework

Thanks!
