On the Ibuildings techPortal today there's a new post from Marcello Duarte following up on his previous post looking at behavior driven development (here) with a look at PHPSpec, a port of RSpec that is the first PHP BDD framework.
PHPSpec is the first ever PHP BDD framework. It is a port of RSpec to PHP created back in 2007 by Padraic Brady and Travis Swicegood. Development in this framework stopped for a while and was reignited last August (2010).
He goes over how to get it installed via PEAR and how to write some sample tests following along the topic from his previous post (handing videos and reviews). He gets into a bit more detail by describing how MVC is handled with PHPSpec and how the Zend Framework command line tool can be used to create a controller that satisfies the test.
