One of the most exciting thing in Ruby and Ruby frameworks like Rails and Merb is Behavior Driven Development framework - RSpec. Generally BDD provides new quality in testing and documenting our code. RSpec is a brilliant example of Ruby possibilities, I mean DSL ( Domain Specific Language ). But like I said last time DSLs aren’t only Ruby but also (or maybe more) Smalltalk. We know that “Smalltalk can do nothing but build domain specific languages”, so it’s natural that we should have something like RSpec in our Smalltalk world, and we have ! It called SSpec. Of course you probably say that we have SUnit which is satisfactory, and you’re right. What is more SUnit is excellent and like everything in my favorit Squeak outstanding integrated with it. But it’s still TDD, and what we need here is BDD - next generation of testing family. So if you want to try it, go to the www.squeaksource.com/SSpec/ and download it, helpfuly will be also SSpec documentation which you can download here:

SSpec is maybe not so active and popular like RSpec but really interesting, so if you want to try BDD testing in your Smalltalk project you should use it
