如何使用 PHPUnit 测试 Symfony2 模型

Question

我一直在尝试在 Symfony2 项目中测试模型，但我不知道如何让实体管理器保存和检索记录。

谁能给我指出正确的文档吗？

Answer 1

为了测试您的模型，您可以使用 setUp() 方法。 文档链接

use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;

class MyModelTest extends WebTestCase
{
    /**
     * @var EntityManager
     */
    private $_em;

    protected function setUp()
    {
        $kernel = static::createKernel();
        $kernel->boot();
        $this->_em = $kernel->getContainer()->get('doctrine.orm.entity_manager');
        $this->_em->beginTransaction();
    }

    /**
     * Rollback changes.
     */
    public function tearDown()
    {
        $this->_em->rollback();
    }

    public function testSomething()
    {
        $user = $this->_em->getRepository('MyAppMyBundle:MyModel')->find(1);
    }

希望这对您有帮助

Symfony2 模型应该是代表代码中的域模型的域对象。

域对象的定义应该纯粹是为了实现业务
相应领域概念的行为，而不是被定义
通过更具体的技术框架的要求。 -- 领域驱动设计 - 维基百科，免费百科全书

领域对象（及其测试）不应该依赖 Symfony2 API 和 Doctrine API，除非你真的想测试它们自己。

编写 Symfony2 单元测试与编写标准 PHPUnit 单元测试没有什么不同。 -- Symfony - 测试

您可以测试业务逻辑（流程、规则、行为、等）用 PHPUnit（或 Behat）在域对象中表示，通常 测试双打。
