Passing Arguments into Symfony 3 Form configureOptions

I have the following form:

class TestFormType extends AbstractType
{
    protected $testArgument;

    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        if (isset($options['testArgument'])) {
            $this->testArgument = $options['testArgument'];
        }

        $builder->add('textField', 'Symfony\Component\Form\Extension\Core\Type\TextType');
    }

    public function configureOptions(OptionsResolver $optionsResolver)
    {
        $optionsResolver->setRequired('testArgument');

        $optionsResolver->setDefaults(
            array(
                'data_class' => get_class($this->testArgument)
            )
        );
    }
}

I am passing the value for the testArgument attribute via form options (Symfony 3 modifications), but when is comes to get the class name of the attribute to set the 'data_class' inside configureOptions method, it is always null. Basically I need to depend on the form type class attribute inside the configureOptions method.Can someone please help me out here to the right direction ?

You should pass the *Type __constructor for use to

use App\Entity\Blog;  
use Symfony\Component\Form\AbstractType;  
use Symfony\Component\OptionsResolver\OptionsResolver;

class BlogType extends AbstractType {

    private $someDependency;

    public function __construct($someDependency)
    {
        $this->someDependency = $someDependency;
    }
    // ...

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults([
            'empty_data' => new Blog($this->someDependency),
        ]);
    } }

I had to pass the dependency in configureOptions method from the form factory create method itself:

$form = $this->factory->create(
            'app\TestBundle\Form\Type\TestFormType',
            $this->testArgument,
            array(
                'data_class' => get_class($this->testArgument)
            )
        );

as it would not be set by the default settings in the form type and had to refactor the form type class as follows:

class TestFormType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('textField', 'Symfony\Component\Form\Extension\Core\Type\TextType');
    }
}
