通过单元测试访问Symfony 2容器？

Question

如何在单元测试中访问Symfony 2容器？我的图书馆需要它,所以它是必不可少的.

测试类扩展,\PHPUnit_Framework_TestCase因此没有容器.

Answer 1

现在支持Symfony.请参阅http://symfony.com/doc/master/cookbook/testing/doctrine.html

这是你可以做的:

namespace AppBundle\Tests;

use Symfony\Bundle\FrameworkBundle\Test\KernelTestCase;

class MyDatabaseTest extends KernelTestCase
{
    private $container;

    public function setUp()
    {
        self::bootKernel();

        $this->container = self::$kernel->getContainer();
    }
}

有关更现代和可重复使用的技术,请参阅https://gist.github.com/jakzal/a24467c2e57d835dcb65.

请注意,在单元测试中使用容器会闻到异味.一般来说,这意味着你的类依赖于整个容器(整个世界),这并不好.您应该限制依赖关系并模拟它们.

Answer 2

您可以在设置功能中使用它

protected $client;
protected $em;

/**
 * PHP UNIT SETUP FOR MEMORY USAGE
 * @SuppressWarnings(PHPMD.UnusedLocalVariable) crawler set instance for test.
 */
public function setUp()
{
    $this->client = static::createClient(array(
            'environment' => 'test',
    ),
        array(
            'HTTP_HOST' => 'host.tst',
            'HTTP_USER_AGENT' => 'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:20.0) Gecko/20100101 Firefox/20.0',
    ));

    static::$kernel = static::createKernel();
    static::$kernel->boot();
    $this->em = static::$kernel->getContainer()
                               ->get('doctrine')
                               ->getManager();
    $crawler = $this->client->followRedirects();
}

不要忘记设置你的拆解功能

    protected function tearDown()
{
    $this->em->close();
    unset($this->client, $this->em,);
}
