Domain-Driven Design in PHP

By: Keyvan Akbary, Carlos Buenosvinos, Christian Soronellas

Overview of this book

Domain-Driven Design (DDD) has arrived in the PHP community, but for all the talk, there is very little real code. Without being in a training session and with no PHP real examples, learning DDD can be challenging. This book changes all that. It details how to implement tactical DDD patterns and gives full examples of topics such as integrating Bounded Contexts with REST, and DDD messaging strategies. In this book, the authors show you, with tons of details and examples, how to properly design Entities, Value Objects, Services, Domain Events, Aggregates, Factories, Repositories, Services, and Application Services with PHP. They show how to apply Hexagonal Architecture within your application whether you use an open source framework or your own.

Testing Repositories


In order to be sure that the Repository will work in production, we'll need to test its implementation. To do this, we have to test the boundaries of the system, making sure that our expectations are correct.

In the case of a Doctrine test, the setup will be a little bit more sophisticated:

use Doctrine\DBAL\Types\Type;
use Doctrine\ORM\EntityManager;
use Doctrine\ORM\Tools;
use Domain\Model\Post;

class DoctrinePostRepositoryTest extends \PHPUnit_Framework_TestCase
{
    private $postRepository;

    public function setUp()
    {
        $this->postRepository = $this->createPostRepository();
    }

    private function createPostRepository()
    {
        $this->addCustomTypes();
        $em = $this->initEntityManager();
        $this->initSchema($em);

        return new PrecociousDoctrinePostRepository($em);
    }

    private function addCustomTypes()
    {
        if (!Type::hasType('post_id')) {
            Type::addType(
                'post_id'...
