سلام و خسته نباشید، هر کاری میکنم class not found میگیرم.

namespace app\\models;
class User {
    private string $name;
    public function getName(): string{
        return $this->name;
    }
    public function setName(string $name): void{
        $this->name = $name;
    }
}

use PHPUnit\\Framework\\TestCase;
use app\\models\\User;
class UserTest extends TestCase {
    function testUserFirstName() {
        $user = new User();
        $user->setName('ehsan');
        self::assertEquals('ehsan', $user->getName());
    }
}
