Как исправить ошибку при выполнении тестов Codeception с модулем Yii2?

Question

[Bombadile]

Есть тест Codeception. Без включенного модуля Yii2 - ошибок нет.

А если в unite.suite.yml включен модуль Yii2:

class_name: UnitTester
modules:
    enabled:
        - Asserts
        - \Helper\Unit
        - Yii2:
                 configFile: 'tests/config/unit.php'
                 part: fixtures

Появляется ошибка:
An Error occurred while handling another error:
PHPUnit_Framework_Exception: Trying to get property of non-object

Тест:

namespace mobile\tests\unit;

class CheckoutTest extends \yii\codeception\TestCase
{
    public function testCartcheck()
    {
        $i = 80;
        expect('equal 80', $i)->equals(80);
    }
}

Логи:
An Error occurred while handling another error:
PHPUnit_Framework_Exception: Trying to get property of non-object

Попробуйте наследоваться не от \yii\codeception\TestCase, а от \Codeception\Test\Unit
вот так

class CheckoutTest extends \Codeception\Test\Unit
{
    public function testCartcheck()
    {
        $i = 80;
        expect('equal 80', $i)->equals(80);
    }
}
