Php symfony的单元测试问题

)

由于两天来我对查询进行了单元测试，我遇到了一些问题，下面是代码和测试：

请求：

<?php

namespace CampaignBundle\Service;

use Doctrine\ORM\EntityManager;
use AccessBundle\Model\UserInterface;
use AccessBundle\Service\CountryFilter;

class CampaignProvider
{
    /** @var EntityManager */
    protected $em;

    /** @var CountryFilter */
    protected $countryFiler;

    /**
     * CampaignProvider constructor.
     * @param EntityManager $entityManager
     * @param CountryFilter $countryFilter
     */
    public function __construct(EntityManager $entityManager, CountryFilter $countryFilter)
    {
        $this->em = $entityManager;
        $this->countryFiler = $countryFilter;
    }

    /**
     * @return \Doctrine\ORM\EntityRepository|CampaignBundle\Entity\CampaignRepository
     */
    protected function getRepository()
    {
        return $this->em->getRepository('CampaignBundle:Campaign');
    }

    /**
     * @return array
     * @throws \Exception
     */
    public function getCampaign()
    {
        $queryBuilder = $this->getCampaignQb();

        return $queryBuilder->getQuery()->getResult();
    }

    /**
     * @return \Doctrine\ORM\QueryBuilder
     * @throws \Exception
     */
    public function getCampaignQb()
    {
        $repository = $this->getRepository();

        $queryBuilder = $repository->createQueryBuilder('c');

        $queryBuilder
            ->where('c.isDeleted = 0')
            ->addOrderBy('c.id', 'DESC');

        return $queryBuilder;
    }
}

我承认我在测试查询时遇到了一些问题，你能帮我吗

谢谢；）

编辑： 编辑我的全部帖子

---

ps:CountryFilter是我在活动提供程序中调用的一项服务

您在模拟实体管理器，但在测试中没有将其传递给活动提供程序：

$this->活动提供程序

不知道本地

$entityManager

变量

---

如果使用构造函数注入，则需要将其放在构造函数调用中；如果使用方法注入，则需要将其放在

setEntityManager

方法中。

您是否在entity one中声明了repository类？您好，是的，我这样做了（我编辑了我的帖子以显示如何获取存储库），请您跳过整个类！不仅仅是方法。谢谢我再次编辑了sorryhello，通常我是在测试类的设置中编辑的，我编辑了我的帖子现在你可以在测试中看到它，你仍然在使用局部变量（

$repository

和

$entityManager

），但是你应该使用你在

设置

函数中创建的变量（

$this->repository

和

$this->entityManager

）。您不必为它们创建新的模拟。
