Question

I’m doing test unit of my entity:

namespace PathtomyBundle\Tests;

require_once dirname(__DIR__).'/../../../app/AppKernel.php';

use Doctrine\ORM\Tools\SchemaTool;

abstract class TestCase extends \PHPUnit_Framework_TestCase
{
/**
 * @var Symfony\Component\HttpKernel\AppKernel
 */
protected $kernel;

/**
 * @var Doctrine\ORM\EntityManager
 */
protected $entityManager;

/**
 * @var Symfony\Component\DependencyInjection\Container
 */
protected $container;

public function setUp()
{
    // Boot the AppKernel in the test environment and with the debug.
    $this->kernel = new \AppKernel('test', true);
    $this->kernel->boot();

    // Store the container and the entity manager in test case properties
    $this->container = $this->kernel->getContainer();
    $this->entityManager = $this->container->get('doctrine')->getEntityManager();

    // Build the schema for sqlite
    //$this->generateSchema();

    parent::setUp();
}

public function tearDown()
{
    // Shutdown the kernel.
    $this->kernel->shutdown();

    parent::tearDown();
}

protected function generateSchema()
{
    // Get the metadatas of the application to create the schema.
    $metadatas = $this->getMetadatas();

    if ( ! empty($metadatas)) {
        // Create SchemaTool
        $tool = new SchemaTool($this->entityManager);
        $tool->createSchema($metadatas);
    } else {
        throw new Doctrine\DBAL\Schema\SchemaException('No Metadata Classes to process.');
    }
}

/**
 * Overwrite this method to get specific metadatas.
 *
 * @return Array
 */
protected function getMetadatas()
{
    return $this->entityManager->getMetadataFactory()->getAllMetadata();
}
}

and also:

 namespace pathtomybundle\Tests\Entity;
 use pathtomybundle\Tests\TestCase;
 use pathtomybundle\Entity\Calendars;

 require_once dirname(__DIR__).'/TestCase.php';

 class CalendarsDbTest extends TestCase
 {

protected $Calendars;

    public function setUp()
        {
            parent::setUp();

            $this->Calendars = new Calendars();
        }


    public function testGenerateCalendars()
    {

        $this->Calendars->setBeginDate(new \DateTime('now'));
        $this->Calendars->setDescription('Description');
        $this->Calendars->setEndDate(new \DateTime('now'));
        $this->Calendars->setType('sur titre');

        // Save the ExCalendars
        $this->entityManager->persist($this->Calendars);
        $this->entityManager->flush();



    }

       public function testUser(){

     $this->assertEquals('Description', $this->Calendars->getDescription() );

    }

So my questions are:

• Why does it raise this error “Failed asserting that null matches expected”?

• Why getDescription() returns NULL?

• How to test two table with One-to-Many relationship for example my Table Calendars with another table in database?

Edit

For the third question :

For example I have two Tables Job and Calenders with Many-to-One relationship so I will have a Job_Id field in Calendars Table,so how I will do my test Unit with a foreign key “job_id”

In Calendars Entity :

 /**
 * @var Job
 *
 * @ORM\ManyToOne(targetEntity="Job")
 * @ORM\JoinColumns({
 *   @ORM\JoinColumn(name="job_id", referencedColumnName="job_id")
 * })
 */
private $jobId;

Edit-2-

when I run my phpunit test “phpunit -c app” to test setters function and persist in database so I have a with every test a new data insered in databse, my question is it possible to do a lot of test but I insert data in database just for one time because actually I must remove data from database with every test.

2 – another question : to create a database_test i use “$this->generateSchema();
” so after create a database for the first time and when the test call “TestCase”class (the code above) again so he tried to create the database_test again then I must remove the line after the first time and it’s not good,so what I can do to run this line just for one time in the first time when i run my test?

Edit-3

    /**
 * @var Job
 *
 * @ORM\ManyToOne(targetEntity="Job")
 * @ORM\JoinColumns({
 *   @ORM\JoinColumn(name="job_id", referencedColumnName="id")
 * })
 */
private $job;

it’s normal?

Answer 1

1. Every test in test case creates his own CalendarsDbTest object. So, in fact, $this->Calendar is different object in each test (if you want share it between tests you need create it in setUp method)

2. Is the same as above (there is null because you never call setDescription with $this->Calendars – it’s different object than it is in first test)

3. I’m not sure what exactly you mean. Can you show more precise (for example method you want test) what you mean?

edit:

The answer is: you don’t test it. Why? Because unit test is UNIT test – you should test here only your entity. Persistence, keeping relations etc. are Doctrine resposibility and should be tested there – you don’t worry about it.

The only thing you should test is setter/getter for $jobId property (btw. it should be “$job” rather than “$jobId” because it’s object of Job class – not an integer), eg.:

class CalendarTest extends \PHPUnit_Framework_TestCase
{
     (...)

     public function testSetGetJob()
     {
         $job = new Job();
         $job->setSomeProperty('someValue');  

         $expectedJob = clone $job; // you clone this because in setter you pass object by reference  

         $calendar = new Calendar();
         $calendar->setJob($job);

         $this->assertEquals($expectedJob, $calendar->getJob());
     }

     (...)
}
