easyb is a free, open source and behavior driven development framework for the Java platform. By using a specification based Domain Specific Language, easyb aims to enable executable, yet readable documentation.
Behavior driven development (or BDD) isn`t anything new or revolutionary-- it`s just an evolutionary offshoot of test driven development, in which the word test is replaced by the word should.
Semantics aside, a lot of people have found that the concept of should is a much more natural development driver than the concept of testing.
In fact, when you think in terms of behavior (i.e. shoulds) you`ll find that writing specifications is easier to do first, which is the intent of test driven development in the first place.
asyb enables you to verify behavior of normal Java objects, work-flows, etc (basically, anything you write in Java) in a more natural way-- for instance, imagine having a conversation with a customer who wants you to write something to validate zip codes.
