Question

我正在使用PHPUnit测试我的Symfony2项目。我想在做一些功能测试时模拟服务器的时钟。

AuthUserRepositoryTest.php

<?php
namespace AppBundle\Tests\Entity;
use AppBundle\Entity\AuthUserRepository;
use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;
use \Symfony\Bridge\PhpUnit\ClockMock;
/**
 * @group time-sensitive
 */
class AuthUserRepositoryTest extends WebTestCase
{
    /**
     * @var AuthUserRepository
     */
    private $AuthUserRepository;

    public function setUp()
    {
        $kernel = static::createKernel();
        $kernel->boot();
        $this->AuthUserRepository = $kernel->getContainer()
            ->get('doctrine.orm.entity_manager')
            ->getRepository('AppBundle:auth_user');
        ClockMock::register(__CLASS__);
    }

    /**
     * @group time-sensitive
     */
    public function test()
    {
        ClockMock::withClockMock(true);

        // Other tests ...

        // Check whether clock mock was successful
        $time = $this->AuthUserRepository->getApparentTime();
        $this->assertEquals("2016-11-05 01:00:00",$time);
    }

    /**
     * Override time() in current namespace for testing
     *
     * @return int
     */
    public static function time()
    {
        return "2016-11-05 01:00:00";
    }
    ?>

AuthUserRepository.php

<?php
namespace AppBundle\Entity;
use Doctrine\ORM\EntityRepository;

class AuthUserRepository extends EntityRepository{

    private function getTimeStamp()
    {
        return \DateTime::createFromFormat('U', time())->setTimezone(new \DateTimeZone('Asia/Colombo'))->format('Y-m-d H:i:s');
    }

    public function getApparentTime()
    {
        return $this->getTimeStamp();
    }

    // Functions to be tested are reduced.
}
?>

如果时钟模拟成功，assertEquals应该通过。但它没有通过，实际时间保持不变。无法断言两个字符串相等。

赞赏任何实现愿望功能的建议。

像这样使用ClockMock::withClockMock：

ClockMock::withClockMock(strtotime('2016-11-05 01:00:00'));

此外，无需覆盖time()函数。
