我的测试有问题。我学习了如何编写phpunit测试，以及如何模拟对象、服务等
<?php
namespace AppService;
use AppEntityProduct;
use AppRepositoryProductRepository;
use DoctrineORMEntityManager;
use DoctrineORMEntityManagerInterface;
use DoctrineORMORMException;
use SymfonyComponentHttpKernelExceptionNotFoundHttpException;
use SymfonyComponentValidatorValidatorValidatorInterface;
class ProductService
{
/**
* @var ProductRepository
*/
private $productRepository;
/**
* @var EntityManager
*/
private $entityManager;
/**
* @var ValidatorInterface
*/
private $validator;
/**
* ProductService constructor.
* @param ProductRepository $productRepository
* @param EntityManagerInterface $entityManager
* @param ValidatorInterface $validator
*/
public function __construct(ProductRepository $productRepository, EntityManagerInterface $entityManager, ValidatorInterface $validator)
{
$this->productRepository = $productRepository;
$this->entityManager = $entityManager;
$this->validator = $validator;
}
/**
* @param $productData
* @return Product|string
*/
public function createProduct($productData)
{
$name = $productData['name'];
$quantity = $productData['quantity'];
$sku = $productData['sku'];
$product = new Product();
$product->setName($name);
$product->setQuantity($quantity);
$product->setProductSerial($sku);
$errors = $this->validator->validate($product);
if (count($errors) > 0) {
$errorsString = (string)$errors;
return $errorsString;
}
try {
$this->entityManager->persist($product);
$this->entityManager->flush();
return $product;
} catch (Exception $ex) {
return $ex->getMessage();
}
}
}
我写了这个测试：
<?php
namespace AppTestsService;
use AppEntityProduct;
use AppRepositoryProductRepository;
use AppServiceProductService;
use DoctrineCommonPersistenceObjectRepository;
use PHPUnitFrameworkTestCase;
class ProductServiceTest extends TestCase
{
/**
* Create product test
*/
public function testCreateProduct()
{
$product = new Product();
$product->setName('tester');
$product->setQuantity(2);
$product->setProductSerial('Examplecode');
$productService = $this->createMock(ProductService::class);
$productService->method('createProduct')->will($this->returnSelf());
$this->assertSame($productService, $productService->createProduct($product));
}
}
当我运行phpunit测试时，我总是成功的，但我的数据库是空的。我如何才能确保测试工作正常？哪些值得修复，哪些不值得修复？我想让测试的启动产生结果，例如，向测试数据库中添加记录，但我不知道如何做到这一点，也不知道如何正确地模拟它。我使用phpunit+Symfony 4。
我曾经写过测试，但那些要求端点API的测试，在这里我想测试没有端点的服务和存储库。
我想学习如何测试和模拟网站，存储库，各种类等
当我申请答案时，我有：

首先，当您模拟一个方法时，在这个测试中，原始方法已经不存在了。在您的情况下，您可以用以下内容替换ProductService::createProduct：
// This is your mock
class ProductService
{
// ...
public function createProduct($productData)
{
return $this;
}
}
你的测试没有检查任何东西。
如果你想测试真正的功能，那么
namespace AppTestsService;
use AppRepositoryProductRepository;
use AppServiceProductService;
use SymfonyBundleFrameworkBundleTestKernelTestCase;
use SymfonyComponentValidatorValidatorValidatorInterface;
class ProductServiceTest extends KernelTestCase
{
/**
* Create product test
*/
public function testCreateProduct(): void
{
// We load the kernel here (and $container)
self::bootKernel();
$productData = [
'name' => 'foo',
'quantity' => 1,
'sku' => 'bar',
];
$productRepository = static::$container->get('doctrine')->getRepository(ProductRepository::class);
$entityManager = static::$container->get('doctrine')->getManager();
// Here we mock the validator.
$validator = $this->getMockBuilder(ValidatorInterface::class)
->disableOriginalConstructor()
->setMethods(['validate'])
->getMock();
$validator->expects($this->once())
->method('validate')
->willReturn(null);
$productService = new ProductService($productRepository, $entityManager, $validator);
$productFromMethod = $productService->createProduct($productData);
// Here is you assertions:
$this->assertSame($productData['name'], $productFromMethod->getName());
$this->assertSame($productData['quantity'], $productFromMethod->getQuantity());
$this->assertSame($productData['sku'], $productFromMethod->getSku());
$productFromDB = $productRepository->findOneBy(['name' => $productData['name']]);
// Here we test that product in DB and returned product are same
$this->assertSame($productFromDB, $productFromMethod);
}
}
