Symfony 2.1 form unit testing on bind event - symfony

Question

I am trying to test a method on the bind event of a custom form type.
Here is the code
public function bind(DataEvent $event)
{
$form = $event->getForm();
if($form->getNormData() instanceof BaseFileInterface && !$event->getData() instanceof UploadedFile) {
$event->setData($form->getNormData());
}
if($event->getData() instanceof UploadedFile) {
$hander = $this->handlerManager->getHandler(
$form->getParent()->getConfig()->getDataClass(),
$form->getName()
);
$datas = $hander->createBaseFile($event->getData());
$event->setData($datas);
}
if(is_string($event->getData())) {
$event->setData(null);
}
}
and the form builder of the type :
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->addEventSubscriber(new BaseFileListener($this->handlerManager))
->addViewTransformer(new BaseFileToStringTransformer())
;
}
My test class inherits from Symfony\Component\Form\Tests\FormIntegrationTestCase and is doing this :
protected function setUp()
{
parent::setUp();
$this->handlerManager = $this->getHandlerManagerMock();
$this->dispatcher = $this->getMock('Symfony\Component\EventDispatcher\EventDispatcherInterface');
$this->builder = new FormBuilder(null, null, $this->dispatcher, $this->factory);
$this->form = $this->factory->create('my_file');
$this->form->setParent($this->getFormMock())->setData(new DummyEntity());
}
protected function getFormMock()
{
$mock = $this
->getMockBuilder('Symfony\Component\Form\Tests\FormInterface')
->disableOriginalConstructor()
->getMock()
;
return $mock;
}
public function testBindHandleNewFileWithNonEmptyField()
{
$data = $file = new UploadedFile(
__DIR__.'/../Fixtures/test.gif',
'original.gif',
'image/gif',
filesize(__DIR__.'/../Fixtures/test.gif'),
null
);
$event = new FormEvent($this->form, $data);
$listener = new BaseFileListener($this->handlerManager);
$listener->bind($event);
$this->assertInstanceOf('My\FooBundle\Entity\BaseFileInterface', $event->getData());
$this->assertNotEquals($event->getData(), $this->form->getNormData());
}
The probleme is that the $form->getParent()->getConfig()->getDataClass() throws an exception on getDataClass ().
The question is how to build the form correctly to perform the bind test ?

Ok, answering my self :)
Here is the good mocking in phpunit :
protected function setUp()
{
parent::setUp();
$this->handlerManager = $this->getHandlerManagerMock();
$this->dispatcher = $this->getMock('Symfony\Component\EventDispatcher\EventDispatcherInterface');
$this->builder = new FormBuilder(null, null, $this->dispatcher, $this->factory);
$this->form = $this->factory->create('my_file');
$this->form->setParent($this->getFormMock());
}
protected function getFormMock()
{
$mock = $this->getMock('Symfony\Component\Form\Tests\FormInterface');
$mock
->expects($this->any())
->method('getConfig')
->will($this->returnValue($this->getFormConfigMock()))
;
return $mock;
}
protected function getFormConfigMock()
{
$mock = $this->getMockBuilder('Symfony\Component\Form\FormConfigInterface')
->disableOriginalConstructor()
->getMock();
$mock
->expects($this->any())
->method('getDataClass')
->will($this->returnValue('My\FooBundle\Tests\DummyEntity'))
;
return $mock;
}
I thought I could manage to rebuild the entire form without using mock, but it seems impossible.
If someone has a better solution to offer I'm interested.
