Add TransactionStrategy, add helper trait

[msmakouz]

Features

TransactionStrategy

A new TransactionStrategy has been implemented, utilizing the MigrationStrategy without executing migration and rollback for each test. Instead, it initiates migration before the first test execution and encapsulates each test's execution within a transaction before running it.

To use this strategy, add the Spiral\DatabaseSeeder\Database\Traits\Transactions trait to your base TestCase for tests that use a database.

namespace Tests;

use Spiral\DatabaseSeeder\Database\Traits\Transactions;
use PHPUnit\Framework\TestCase;

abstract class DatabaseTestCase extends TestCase
{
    use Transactions;
}

Helper

A Spiral\DatabaseSeeder\Database\Traits\Helper trait has been added, encompassing a set of useful testing methods:

• getDatabaseCleaner
• getCurrentDatabase
• getCurrentDatabaseDriver
• getCurrentDatabaseProvider
• getOrm
• getEntityManager
• detachEntityFromIdentityMap
• cleanIdentityMap
• getRepositoryFor
• persist

use Spiral\DatabaseSeeder\Database\Traits\Helper;
use PHPUnit\Framework\TestCase;

class DatabaseTestCase extends TestCase
{
    use Helper;
    
    public function testAddUser(): void
    {
        $user = $this->userFactory->create(
            uuid: Uuid::uuid7(),
            email: 'user@site.com',
            name: 'John'
        );

        $this->persist($user);

        $user = $this->getRepositoryFor(User::class)->findByPK($user->uuid);

        $this->assertSame('user@site.com', $user->email);
        $this->assertSame('John', $user->name);
    }
}

The issue with Psalm is related to cycle/database.
