如何从Doctrine 2中的实体创建表

Question

I see similar questions at SO, but they are outdated and no longer actual. So, what I want is to create tables in database using models definition. So, I have a model which looks like so:

<?php

namespace Tests\Integration\Models;

/**
* @Entity
* @Table(name="test_model")
*/
class TestModel
{
    /**
     * @Id @Column(type="integer")
     * @GeneratedValue
     */
    protected $id;

    /** @Column(type="integer") */
    protected $a;


    public function getId()
    {
        return $this->id;
    }

    public function getA()
    {
        return $this->a;
    }

    public function setA($a)
    {
        $this->a = $a;
    }
}

In my unit-test I have a working code, looking like:

    <?php

namespace Tests\Integration;

use PHPUnit\Framework\TestCase;
use Doctrine\ORM\EntityManager;
use Doctrine\ORM\Tools\Setup;
use Tests\Integration\Models\TestModel;
use Tests\Integration\Models\TestModelRepository;


final class IntegrationOrmTest extends TestCase
{
    protected static $em;

    protected static $er;

    public static function setUpBeforeClass()
    {
        $params = [
            'driver' => getenv("TEST_DB_DRIVER"),
            'host' => getenv("TEST_DB_HOST"),
            'dbname' => getenv("TEST_DB_NAME"),
            'user' => getenv("TEST_DB_USER"),
            'password' => getenv("TEST_DB_PASSWORD"),
            'port' => getenv("TEST_DB_PORT"),
        ];

        $config = Setup::createAnnotationMetadataConfiguration(["./Models"], true);
        self::$em = EntityManager::create($params, $config);
        self::$er = new TestModelRepository(self::$em);           
    }

    public function testEquals()
    {
        //works perfectly fine
        $data = new TestModel();
        $data->setA(123);
        self::$er->save($data);
        self::$em->flush();

        $this->assertTrue(true);
    }
}

This code works, just because in my database there is already a table test_model . But I want to create it dynamically in my test suit and destroy it after all tests. How can I do it programmatically?

The Doctrine docs describe schema generation in some detail.

Here is a simple example:

final class IntegrationOrmTest extends TestCase
{
    public static function setUpBeforeClass()
    {
        $params = [
            'driver' => "pdo_mysql",
            'host' => "localhost",
            'dbname' => "s43x",
            'user' => "impd",
            'password' => "JalenHurts",
            //'port' => getenv("TEST_DB_PORT"),
        ];

        $config = Setup::createAnnotationMetadataConfiguration(["./Models"], true);
        self::$em = $em = EntityManager::create($params, $config);

        $tool = new \Doctrine\ORM\Tools\SchemaTool($em);
        $classes = array(
            $em->getClassMetadata(TestModel::class),
        );
        $tool->dropSchema($classes);  // Empty out any current schema
        $tool->createSchema($classes);
