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。

有人能指出我正确的文档吗？

Answer 1

为了测试模型，可以使用setUp（）方法。 link to docs

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);
    }

希望这有助于你

Symfony2模型应该是代码中代表domain models的域对象。

应该纯粹定义域对象以实现业务相应域概念的行为，而不是被定义根据更具体的技术框架的要求。 - Domain-driven design - Wikipedia, the free encyclopedia

域对象（及其测试）不应依赖于Symfony2 API和Doctrine API，除非您真的想要自己测试。

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

您可以使用PHPUnit（或Behat）以及test doubles来测试域对象中表示的业务逻辑（流程，规则，行为等）。
