I’m trying to mock a repository containing all modules, and it has a method called findAll() that returns all elements from that repository. I cant seem to be able to pull any data from the mocked repository. Any ideas how I could fix it?
Mocking repository:
$moduleRepository = $this->createMock(ModuleRepository::class);
Trying to use method from ModuleRepository class called findAll() that returns all elements from the repo in an array.
$moduleRepository->expects($this->any())
->method('findAll')
->willReturn([]);
Thats what I get when I print $moduleRepository:

I tried it like this and the method actually gets called, but the repo has no data for it to find.
$moduleRepository->expects($this->any())
->method('findAll')
->willReturn([]);
$myDebugVar = $moduleRepository->findAll();
fwrite(STDERR, print_r($myDebugVar, TRUE));
Output:
Array()

Answer
Your moduleRepository will always return empty array, because you said to do it.
here you said to return an empty array []:
->willReturn([]);
from method findAll:
->method('findAll')
There are some ways how to handle it, but for now, I recommend you to create a new database only for testing purposes, then create a new .env.test file which will extend the original .env file and use the exact repository instead of mock.
# .env.test.local DATABASE_URL="mysql://USERNAME:PASSWORD@127.0.0.1:3306/DB_NAME?serverVersion=5.7"
namespace AppTestsRepository;
use DoctrineORMEntityManager;
use SymfonyBundleFrameworkBundleTestKernelTestCase;
final class SomeTest extends KernelTestCase
{
private ?EntityManager $entityManager;
protected function setUp(): void
{
$kernel = self::bootKernel();
$this->entityManager = $kernel->getContainer()
->get('doctrine')
->getManager();
}
public function testSomething()
{
//given
$moduleRepository = $this->entityManager->getRepository(ModuleRepository::class);
//when
$result = $moduleRepository->findAll(...);
//then
$this->assertEquals(...);
}
protected function tearDown(): void
{
parent::tearDown();
// doing this is recommended to avoid memory leaks
$this->entityManager->close();
$this->entityManager = null;
}
}
Be sure you will fill up a new database with the data. It’s a good idea to create fixtures for doing it automatically and clean up the database on tearDown method.
