Как правильно использовать getModule в Codeception?

Question

[ShishMish]

В классе хелпера, в функции создания нового пользователя, хочу использовать методы установленного модуля "Db":

public function createUser()
    {
        // Добавляем клиента
        /**
         * @var $dbm Db
         */
        $dbm = $this->getModule('Db');
        $dbm->_getDbh();
        $dbm->haveInDatabase('site_users', [
            'name' => $this->customerName,
            'solution' => $this->solution,
            'locale' => 'en',
            'active' => '1',
        ]);

При запуске теста в _before которого вызывается эта функция получаю ошибку:

[Error] Call to a member function hasModule() on null

Что я делаю не верно? Как правильно использовать getModule?

$dbh = $this->getModule('Db')->_getDbh();
$dbh->haveInDatabase(...);
