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。

任何人都可以为我指出正确的文档吗？

Answer 1

为了测试你的模型，你可以使用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模型预计是代表domain models代码中的域对象。

域对象应该单纯定义为实现相应的域概念的商业 行为，而不是通过更具体的技术框架的要求来定义 。 - Domain-driven design - Wikipedia, the free encyclopedia

域对象（和它的测试）不应该依赖于Symfony2的API和学说的API，除非你真的想考验一下自己。

写Symfony2单元测试与编写标准PHPUnit单元测试没有区别。 - Symfony - Testing

可以测试业务逻辑域对象使用PHPUnit（或贝哈特）表示的（流程，规则，行为等），并且通常test doubles。

    private $application; 

    public function setUp() 
    { 
     static::$kernel = static::createKernel(); 
     static::$kernel->boot(); 

     $this->application = new Application(static::$kernel); 

     // drop the database 
     $command = new DropDatabaseDoctrineCommand();

     $command->run($input, new NullOutput()); 

     // we have to close the connection after dropping the database so we don't get "No database selected" error 
     $connection = $this->application->getKernel()->getContainer()->get('doctrine')->getConnection(); 
     if ($connection->isConnected()) { 
      $connection->close(); 
     } 

     // create the database 
     $command = new CreateDatabaseDoctrineCommand(); 
     $this->application->add($command); 
     $input = new ArrayInput(array(

     $command->run($input, new NullOutput());

     // get the Entity Manager 
     $this->em = static::$kernel->getContainer()

      ->getManager(); 

     // load fixtures 
     $client = static::createClient(); 
     $loader = new \Symfony\Bridge\Doctrine\DataFixtures\ContainerAwareLoader($client->getContainer()); 
     $loader->loadFromDirectory(static::$kernel->locateResource('@IbwJobeetBundle/DataFixtures/ORM')); 
     $purger = new \Doctrine\Common\DataFixtures\Purger\ORMPurger($this->em); 
     $executor = new \Doctrine\Common\DataFixtures\Executor\ORMExecutor($this->em, $purger); 
     $executor->execute($loader->getFixtures()); 
    } 

    public function testFunction() 
    { 
      // here you test save any object or test insert any object 
    } 

    protected function tearDown() 
    { 
     parent::tearDown(); 
     $this->em->close(); 
    } 
}
