Full stack BDD for Symfony2

Many Symfony2 developers have heard about Behat and even use it regularly in their Symfony projects. If you have found value in this tool and the BDD practices it was inspired on, come join us for this talk as we will expand on what other benefits these practices and other BDD tools available can bring. This very illustrative talk will not only present you with the tools but show how to use them together to build beautifully architected, business-oriented Symfony2 applications.
