I just created the scenarios where the bundle should work on. For that I just created complex forms and checking that everything works properly and has the proper responses.
Also I gave up creating a new mock of symfony environment to use the validation and related and I called the AppKernel of a Symfony instance.
Tested with Symfony 2.3 and 2.4.
##Install phpunit
##From Test Controller
Check the AppKernel url if necessary.
##Run tests
phpunit -c phpunit.xml
