Open Source Behavior-Driven Development (BDD) Tools for PHP
Behavior-Driven Development (BDD) is an Agile approach that mixes requirement gathering, documentation and acceptance testing. The idea is that you start by writing human-readable sentences that describe a feature of your application and how it should work. Then you implement this behavior in software. This description can produce automated tests that will verify that the feature is implemented correctly. On the testing side, BDD tools provide you the features to perform functional or acceptance tests. There are many tools that implement the BDD concept for different languages, including PHP.
