用于测试的 Symfony 模拟存储库

【中文标题】用于测试的 Symfony 模拟存储库【英文标题】:Symfony mocking repository for testing 【发布时间】:2021-09-01 00:21:06 【问题描述】:我正在尝试模拟一个包含所有模块的存储库,它有一个名为 findAll() 的方法,该方法返回该存储库中的所有元素。我似乎无法从模拟存储库中提取任何数据。有什么想法可以解决吗?
模拟存储库:
$moduleRepository = $this->createMock(ModuleRepository::class);
尝试使用 ModuleRepository 类中名为 findAll() 的方法,该方法返回数组中 repo 中的所有元素。
$moduleRepository->expects($this->any())
->method('findAll')
->willReturn([]);
这就是我打印 $moduleRepository 时得到的:

我这样尝试过,该方法实际上被调用了,但是 repo 没有数据可供它查找。
$moduleRepository->expects($this->any())
->method('findAll')
->willReturn([]);
$myDebugVar = $moduleRepository->findAll();
fwrite(STDERR, print_r($myDebugVar, TRUE));
输出:
Array()
【问题讨论】:
调用方法findAll
将返回[]
。它写在你的代码中。你还期待什么?
@u_mulder 我正在尝试调用 ModuleRepository 具有的 findAll 方法,它将返回数组。我知道这个电话很糟糕,这就是为什么我要问如何让它变得更好。
返回什么数组?
ModuleRepository 中所有模块的 @u_mulder。 Repository 有大约 30 个模块,我需要全部获取。
不要模拟 ModuleRepository。只需运行并执行查询。
【参考方案1】:
您的moduleRepository
将始终返回空数组,因为您说过要这样做。
这里你说返回一个空数组[]
:
->willReturn([]);
来自方法findAll
:
->method('findAll')
有一些方法可以处理它,但现在,我建议您创建一个仅用于测试目的的新数据库,然后创建一个新的 .env.test
文件,该文件将扩展原始 .env
文件并使用确切的存储库而不是模拟。
# .env.test.local
DATABASE_URL="mysql://USERNAME:PASSWORD@127.0.0.1:3306/DB_NAME?serverVersion=5.7"
namespace App\Tests\Repository;
use Doctrine\ORM\EntityManager;
use Symfony\Bundle\FrameworkBundle\Test\KernelTestCase;
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;
确保您将用数据填充一个新数据库。为自动执行此操作创建固定装置并在 tearDown
方法上清理数据库是个好主意。
【讨论】:
$this->moduleRepository = self::$container->get(ModuleRepository::class);
我收到这些错误:Incompatible types: Expected property of type '\App\Core\Repository\ModuleRepository', '\App\Core\Repository\ModuleRepository|null|object' provided
和这个:Symfony\Component\DependencyInjection\Exception\ServiceNotFoundException: You have requested a non-existent service "monolog.handler.swift".
@Kacper 我认为它应该类似于self::$container->getEntityManager()->getRepository()
,我认为存储库未定义为服务。
是的,你是对的,谢谢@u_mulder。我将根据您的建议编辑我以前的帖子
Doctrine\Persistence\Mapping\MappingException: The class 'App\Core\Repository\ModuleRepository' was not found in the chain configured namespaces App\Core\Entity, App\Epa\Entity, App\Minerals\Entity, App\UserManagement\Entity, App\HrManagement\Entity, App\Calculator\Entity, App\Catalogue\Entity, App\CountryManagement\Entity, App\Cart\Entity, App\Inventory\Entity, App\Log\Entity, App\Prices\Entity, Gesdinet\JWTRefreshTokenBundle\Entity
程序为什么要在实体列表中寻找repository?
请告诉我您的存储库,我们的信息太少,无法为您提供正确答案。以上是关于用于测试的 Symfony 模拟存储库的主要内容,如果未能解决你的问题,请参考以下文章
