What are the alternatives for testing commonjs modules?

Question

What javascript testing frameworks there support testing commonjs modules?

Answer 1

I used expresso from Visionmedia in node.js

https://github.com/visionmedia/expresso

It extends the basic functions of assert http://nodejs.org/docs/v0.4.7/api/assert.html

So, the default style is:

exports['test String#length'] = function() { assert.equal(6, 'foobar'.length); }; 

can do DRYer

 exports['test String#length'] = function(){ assert.length(6, 'foobar'); }; 

Answer 2

It looks like they have their own UnitTesting infrastructure
