سلام. من این قسمت تا تا دقیقه ۱:۳۷ جلو اومدم

این هم کل کد‌های من در اون فایل:

namespace Tests\\Unit;
use App\\Contracts\\DatabaseConnectionInterface;
use App\\Database\\PDODatabaseConnection;
use App\\Exceptions\\databaseConnectionException;
use App\\Helpers\\Config;
use PDO;
use PHPUnit\\Framework\\TestCase;
class PDODatabaseConnectionTest extends TestCase
{
    public function testPDODatabaseConnectionImplementsDatabaseConnectionInterface()
    {
        $config = $this->getConfig();
        $pdoConnection = new PDODatabaseConnection($config);
        $this->assertInstanceOf(DatabaseConnectionInterface::class, $pdoConnection);
    }
    public function testConnectMethodShouldBeConnectToDatabase()
    {
        $config = $this->getConfig();
        $pdoConnection = new PDODatabaseConnection($config);
        $pdoConnection->connect();
        $this->assertInstanceOf(PDO::class, $pdoConnection->getConnection());
    }
    public function testItThrowExceptionIfConfigIsInvalid()
    {
        $config = $this->getConfig();
        $config['database'] = 'bug_tracker';
        $pdoConnection = new PDODatabaseConnection($config);
        $pdoConnection->connect();
    }
    private function getConfig()
    {
        return Config::get('database', 'pdo_testing');
    }
}

حالا بعد از اجرای تست این ارور رو میده. در حالی که باید بگه: [1049] Unknown database 'dummy'

class databaseConnectionException extends Exception
