Doctrine ORM create method phpspec test failure - orm

Question

I try to write, at first glance, it would seem a trivial test for my repository's "update" method:
<?php
declare(strict_types=1);
namespace Paneric\Authorization\ORM\Repository;
use Doctrine\ORM\EntityManagerInterface;
use Doctrine\ORM\ORMException;
use Paneric\Authorization\DTO\FieldDTO;
use Paneric\Authorization\ORM\Entity\Field;
use Doctrine\ORM\EntityRepository;
use Paneric\Authorization\Interfaces\FieldRepositoryInterface;
class FieldRepository extends EntityRepository implements FieldRepositoryInterface
{
const ENTITY_CLASS = Field::class;
public function __construct(EntityManagerInterface $_em)
{
parent::__construct($_em, $_em->getClassMetadata(self::ENTITY_CLASS));
}
...
public function update(int $fieldId, FieldDTO $fieldDTO): void
{
try {
$field = $this->find($fieldId);
$field->transfer($fieldDTO);
$this->_em->flush();
} catch (ORMException $e) {
echo $e->getMessage();
}
}
...
}
with a spec method:
<?php
namespace spec\Paneric\Authorization\ORM\Repository;
use Doctrine\ORM\EntityManagerInterface;
use Doctrine\ORM\Mapping\ClassMetadata;
use Doctrine\ORM\QueryBuilder;
use Paneric\Authorization\DTO\FieldDTO;
use Paneric\Authorization\ORM\Entity\Field;
use Paneric\Authorization\ORM\Repository\FieldRepository;
use Doctrine\ORM\AbstractQuery;
use PhpSpec\ObjectBehavior;
use Prophecy\Argument;
class FieldRepositorySpec extends ObjectBehavior
{
public function let(EntityManagerInterface $_em, ClassMetadata $classMetadata)
{
$_em->getClassMetadata(Field::class)->willReturn($classMetadata);
$this->beConstructedWith($_em);
}
...
public function it_updates(Field $field, FieldDTO $fieldDTO, EntityManagerInterface $_em)
{
$fieldId = 1;
$field = $this->find($fieldId);
$field->transfer($fieldDTO)->shouldBeCalled();
$_em->flush()->shouldBeCalled();
$this->update($fieldId, $fieldDTO);
}
...
}
and receive the following error:
Unexpected method call on Double\EntityManagerInterface\EntityManagerInterface\P1:
- find(
null,
1,
null,
null
)
expected calls were:
- getClassMetadata(
exact("Paneric\Authorization\ORM\Entity\Field")
)
- find(
exact("Paneric\Authorization\ORM\Entity\Field"),
exact(1)
)
- flush(
)
Apparently issue is related to the call:
...
$field = $this->find($fieldId);
...
Although the second remark related to getClassMetadata, looks strange, considering the fact that my spec let method:
public function let(EntityManagerInterface $_em, ClassMetadata $classMetadata)
{
$_em->getClassMetadata(Field::class)->willReturn($classMetadata);
$this->beConstructedWith($_em);
}
does its job in case of other spec tests.
Can anyone help me to solve this issue ? Thx in advance.

Answer 1

In my repository's "update" metod, line:
$field = $this->find($fieldId);
has to be replaced by:
$field = $this->_em->find(Field::class, $fieldId);
so the complete spec test looks like:
public function it_updates(Field $field, FieldDTO $fieldDTO, EntityManagerInterface $_em)
{
$fieldId = 1;
$_em->find(Field::class, $fieldId)->willReturn($field);
$field->transfer($fieldDTO)->shouldBeCalled();
$_em->flush()->shouldBeCalled();
$this->update($fieldId, $fieldDTO);
}
