Laravel - 使用Doctrine时的phpUnit测试

Question

I created a project with Laravel + Doctrine (instead of Eloquent) + Angular Routing . I decided to use php unit test for testing API (Controllers , Repositories) Actually I am geting an error while testing a simple method. Here is my code :

DoctorineRestaurantRepositoryTest.php:

    class RestaurantTest extends TestCase
     {
         private $DoctrineRepository;
         public  function setUp() {
             $this->DoctrineRepository = DoctrineRestaurantRepository::class;
           }
        /** @test */
        public function validator()
        {
            $this->DoctrineRepository->setTestVariable(3);
            $this->assertEquals($this->DoctrineRepository->getTestVariable(), 3);
        }
      .
      .
      .
    }

my repository file: (DoctrineRestaurantRepository.php)

class DoctrineRestaurantRepository extends DoctrineBaseRepository
{

    private $testVariable = 0;

    /**
     * @return int
     */
    public function getTestVariable()
    {
        return $this->testVariable;
    }

    /**
     * @param int $testVariable
     */
    public function setTestVariable($testVariable)
    {
        $this->testVariable = $testVariable;
    }

  .
  .
  .
}

I ran test and it gave an error :

Call to a member function setTestVariable() on string

Any suggestion to fix it?

Answer 1

You need to define the class variable or inject the class in the method.

Solution 1

adding new object to the class variable

use DoctrineRestaurantRepository;

class RestaurantTest extends TestCase
{
    private $DoctrineRepository;

    public function __construct()
    {
        $this->DoctrineRepository = new DoctrineRestaurantRepository;
    }
    /** @test */
    public function validator()
    {
        $this->DoctrineRepository->setTestVariable(3);
        $this->assertEquals($this->DoctrineRepository->getTestVariable(), 3);
    }
  .
  .
  .
}

Solution 2

using dependency injection

use DoctrineRestaurantRepository;

class RestaurantTest extends TestCase
{
    private $DoctrineRepository;

    public function __construct(DoctrineRestaurantRepository $repository)
    {
        $this->DoctrineRepository = $repository;
    }
    /** @test */
    public function validator()
    {
        $this->DoctrineRepository->setTestVariable(3);
        $this->assertEquals($this->DoctrineRepository->getTestVariable(), 3);
    }
  .
  .
  .
}
