How to unit test Symfony 4 Form with EntityType field
When I run my test:
$ ./vendor/bin/simple-phpunit tests/Unit/Form/ProductFormTest.php
This is the output in my terminal:
PHPUnit 6.5.8 by Sebastian Bergmann
and contributors.
Runtime: PHP 7.2.4-1+ubuntu16.04.1+deb.sury.org+1 with Xdebug 2.7.0alpha2-dev Configuration: /var/www/project/phpunit.xml.dist

There was 1 error:
1) App\Tests\Unit\Form\ProductFormTest::formSubmitsValidData Symfony\Component\Form\Exception\RuntimeException: Class "App\Entity\Supplier" seems not to be a managed Doctrine entity. Did you forget to map it?

ERRORS! Tests: 1, Assertions: 0, Errors: 1.
This error started after mocking the ManagerRegistry class. It seems that in this unit test there is no mapping for doctrine entities present.
Is there a clean way to test a form with "Symfony\Bridge\Doctrine\Form\Type\EntityType" fields?

First your test case should extends from Symfony\Component\Form\Test\TypeTestCase.
Then your test should look like this:
// Example heavily inspired by EntityTypeTest inside the Symfony Bridge
class ProductTypeTest extends TypeTestCase
{
/**
* @var EntityManager
*/
private $em;
/**
* @var \PHPUnit_Framework_MockObject_MockObject|ManagerRegistry
*/
private $emRegistry;
protected function setUp()
{
$this->em = DoctrineTestHelper::createTestEntityManager();
$this->emRegistry = $this->createRegistryMock('default', $this->em);
parent::setUp();
$schemaTool = new SchemaTool($this->em);
// This is the important part for you !
$classes = [$this->em->getClassMetadata(Supplier::class)];
try {
$schemaTool->dropSchema($classes);
} catch (\Exception $e) {
}
try {
$schemaTool->createSchema($classes);
} catch (\Exception $e) {
}
}
protected function createRegistryMock($name, $em)
{
$registry = $this->getMockBuilder('Doctrine\Common\Persistence\ManagerRegistry')->getMock();
$registry->expects($this->any())
->method('getManager')
->with($this->equalTo($name))
->will($this->returnValue($em));
return $registry;
}
protected function getExtensions()
{
return array_merge(parent::getExtensions(), array(
new DoctrineOrmExtension($this->emRegistry),
));
}
protected function tearDown()
{
parent::tearDown();
$this->em = null;
$this->emRegistry = null;
}
}
