Symfony 3 FormTypeTest - php

Question

Following the Symfony 3.0 manual on testing Form Types, I followed the example for testing forms with dependencies as follows;
<?php
namespace Tests\AppBundle\Form;
use AppBundle\Form\Type\Database\OfficeAssignType;
use Symfony\Component\Form\PreloadedExtension;
use Symfony\Component\Form\Test\TypeTestCase;
class OfficeTypeTest extends TypeTestCase
{
private $entityManager;
protected function setUp()
{
// mock any dependencies
$this->entityManager = $this->getMock('Doctrine\Common\Persistence\ObjectManager');
parent::setUp();
}
protected function getExtensions()
{
// create a type instance with the mocked dependencies
$office = new OfficeType($this->entityManager);
return array(
// register the type instances with the PreloadedExtension
new PreloadedExtension(array($office), array()),
);
}
public function testSubmitValid()
{
$formData = array(
'name' => 'new test office',
'address1' => 'Test new office address',
'city' => 'Test office city',
'phone' => 'testoffice#stevepop.com',
'country' => '235',
'currrency' => '1',
);
// Instead of creating a new instance, the one created in
// getExtensions() will be used
$form = $this->factory->create(OfficeType::class);
// submit data to form
//$form->submit($formData);
//$this->assertTrue($form->isSynchronized());
}
}
When I run the tests, I get the following error
Argument 1 passed to Symfony\Bridge\Doctrine\Form\Type\DoctrineType::__construct() must be an instance of Doctrine\Common\Persistence\ManagerRegistry, none given, called in /www/stevepop.com/symfony/vendor/symfony/symfony/src/Symfony/Component/Form/FormRegistry.php on line 85 and defined
The OfficeType is below;
namespace AppBundle\Form\Type\Database;
use Symfony\Bridge\Doctrine\Form\Type\EntityType;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\FormBuilderInterface;
class OfficeType extends AbstractType {
/**
* {#inheritdoc}
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('name', TextType::class, array(
'required' => true,
));
$builder->add('address1', TextType::class, array(
'required' => true,
));
$builder->add('country', EntityType::class, array(
'class' => 'AppBundle:Country',
'attr' => array(
'class' => 'input-sm',
),
'required' => true,
'placeholder' => "Non selected",
));
$builder->add('currency', EntityType::class, array(
'class' => 'AppBundle:Currency',
'attr' => array(
'class' => 'input-sm',
),
'required' => true,
'placeholder' => "Non selected",
));
}
I am not sure what this means to be honest and will appreciate help from anyone who has done FormType unit tests in Symfony 2.8/3.0.
Thank you.

Try to adding this to your tests:
use Symfony\Bridge\Doctrine\Form\DoctrineOrmExtension;
use Symfony\Bridge\Doctrine\Test\DoctrineTestHelper;
use Symfony\Component\Form\Extension\Core\CoreExtension;
class OfficeType extends AbstractType {
/**
* #var \Doctrine\ORM\EntityManager
*/
private $em;
public function setUp()
{
$this->em = DoctrineTestHelper::createTestEntityManager();
parent::setUp();
}
protected function getExtensions()
{
$manager = $this->createMock('Doctrine\Common\Persistence\ManagerRegistry');
$manager->expects($this->any())
->method('getManager')
->will($this->returnValue($this->em));
$manager->expects($this->any())
->method('getManagerForClass')
->will($this->returnValue($this->em));
return array(
new CoreExtension(),
new DoctrineOrmExtension($manager),
);
}
// your code...
}
