Nightly build in node js

I need some suggestion about tools and module regrading node js. I want to set up nightly build system on my server (My local machine). My motive is testing REST APIs and socket APIs. I am searching tools for it especially socket testing.

I need some extra stuff like code coverage, testing report etc. Is it any tool available in node-js like jenkins + their plugin, JUnit/PHPUnit, phing/puppet and especially should be open source.

Thanks in advance. :)
