How to get entity instance when doing unit test using Symfony and PHPUnit? - symfony

Question

I'm trying to do a unit test in the environment as the title says. However, the method contained in the class under test requires an entity instance as an argument. So I'm trying to get the above entity in a generic homebrew test class that extends the TestCase class but I can't figure out how to do it.
I have little experience with functional testing. I used fixtures at that time, so I'm guessing that I should use fixtures this time too. Is that correct? I would appreciate if you could teach me how to do that as well.
Please let me know, even a little information.
below is the test class, and the interface of the test target.
ps. we are using nelmio/alice bundle.
<?php
declare(strict_types=1);
namespace xxx\xxxx\Tests\Customize\Server\AlladinOffice;
use Codeception\PHPUnit\TestCase;
use Customize\Service\AlladinOffice\CodeFormatter;
use Customize\Service\AlladinOffice\CustomerCode;
use Doctrine\Common\Persistence\ObjectManager;
use Eccube\Repository\CustomerRepository;
use PHPUnit\Framework\MockObject\MockObject;
use Proxies\__CG__\Eccube\Entity\Customer;
use Symfony\Bundle\FrameworkBundle\Test\KernelTestCase;
class CustomerCodeTest extends KernelTestCase
{
/**
* #var CustomerCode
*/
private $sut;
/**
* #var CustomerRepository|MockObject
*/
private $customerRepository;
protected function setUp()
{
$codeFormatter = new CodeFormatter();
$this->sut = new CustomerCode($codeFormatter);
$this->customerRepository = $this->createMock(CustomerRepository::class);
parent::setUp();
}
public function testGetCustomerCode()
{
$actual = $this->sut->getCustomerCode(null);
$expected = 1000000000;
$this->assertEquals($expected, $actual);
// $customer = $this->customerRepository->findBy([], ['id' => 'ASC']);
// dump($customer);exit();
// $actual = $this->sut->getCustomerCode($customer);
$customer = new Customer;
//$customer->set
//$this->customerRepository
//->expects($this->any())
//->method('find')
//->willReturn($);
}
}
<?php
declare(strict_types=1);
namespace Customize\Service\AlladinOffice;
use Eccube\Entity\Customer;
interface CustomerCodeInterface
{
public function getCustomerCode(?Customer $customer): string;
public function getChannelCode(?Customer $customer): string;
public function getRankCode(?Customer $customer): string;
}
for example a detailed method to test.
public function getCustomerCode(?Customer $customer): string
{
if (!$customer) {
return self::DEFAULT_CUSTOMER_CODE;
}
$customerRank = $customer->getXxxCustomer()->getCustomerRank();
$customerChannel = $customerRank ? $customerRank->getCustomerChannel() : null;
if (!$customerChannel || !$customerChannel->isExportToAO()) {
return self::DEFAULT_CUSTOMER_CODE;
}
return $this->formatter->getCustomerCodeFromCustomerId($customer->getId());
}
