Testing symfony 2 forms - forms

Question

I develop new type, but I don't know how I can test it.
Assert annotation is not load and validations is not called.
Could any one please help me?
class BarcodeType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->
add('price');
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'Bundles\MyBundle\Form\Model\Barcode',
'intention' => 'enable_barcode',
));
}
public function getName()
{
return 'enable_barcode';
}
}
A have following model for storing form data.
namepspace Bundles\MyBundle\Form\Model;
class Barcode
{
/**
* #Assert\Range(
* min = "100",
* max = "100000",
* minMessage = "...",
* maxMessage = "..."
* )
*/
public $price;
}
I develop some test like this, the form didn't get valid data but it is valid! (Because annotation is not applied)
I try adding ValidatorExtension but I dont know how can I set constructor paramaters
function test...()
{
$field = $this->factory->createNamed('name', 'barcode');
$field->bind(
array(
'price' => 'hello',
));
$data = $field->getData();
$this->assertTrue($field->isValid()); // Must not be valid
}

Answer 1

Not sure why you need to unit-test the form. Cant You unit test validation of Your entity and cover controller with your expected output?
While testing validation of entity You could use something like this:
public function testIncorrectValuesOfUsernameWhileCallingValidation()
{
$v = \Symfony\Component\Validator\ValidatorFactory::buildDefault();
$validator = $v->getValidator();
$not_valid = array(
'as', '1234567890_234567890_234567890_234567890_dadadwadwad231',
"tab\t", "newline\n",
"Iñtërnâtiônàlizætiøn hasn't happened to ", 'trśżź',
'semicolon;', 'quote"', 'tick\'', 'backtick`', 'percent%', 'plus+', 'space ', 'mich #l'
);
foreach ($not_valid as $key) {
$violations = $validator->validatePropertyValue("\Brillante\SampleBundle\Entity\User", "username", $key);
$this->assertGreaterThan(0, count($violations) ,"dissalow username to be ($key)");
}
}

Answer 2

Functional test. Given that you generate a CRUD with app/console doctrine:generate:crud with routing=/ss/barcode, and given that maxMessage="Too high" you can:
class BarcodeControllerTest extends WebTestCase
{
public function testValidator()
{
$client = static::createClient();
$crawler = $client->request('GET', '/ss/barcode/new');
$this->assertTrue(200 === $client->getResponse()->getStatusCode());
// Fill in the form and submit it
$form = $crawler->selectButton('Create')->form(array(
'ss_bundle_eavbundle_barcodetype[price]' => '12',
));
$client->submit($form);
$crawler = $client->followRedirect();
// Check data in the show view
$this->assertTrue($crawler->filter('td:contains("12")')->count() > 0);
// Edit the entity
$crawler = $client->click($crawler->selectLink('Edit')->link());
/* force validator response: */
$form = $crawler->selectButton('Edit')->form(array(
'ss_bundle_eavbundle_barcodetype[price]' => '1002',
));
$crawler = $client->submit($form);
// Check the element contains the maxMessage:
$this->assertTrue($crawler->filter('ul li:contains("Too high")')->count() > 0);
}
}

Include this line must be in Model and try it after include look like your model.
/* Include the required validators */
use Symfony\Component\Validator\Constraints as Assert;
namespace Bundles\MyBundle\Form\Model;
class Barcode
{
/**
* #Assert\Range(
* min = "100",
* max = "100000",
* minMessage = "min message here",
* maxMessage = "max message here"
* )
*/
public $price;
}
