/**
 * Class ReflexionHelper
 * @package PrestaShop\PrestaShop\Tests\TestCase
 *
 * Provides utilities to access private or protected properties inside classes.
 *
 * Please be careful with these feature, testing private fields or methods is often a bad smell :
 *      - you may be testing your implementation details rather than the behaviour of your code.
 *      - if this is because the class under test is too long and complicated, you should defintely consider breaking this class into several smaller ones.
 *
 * In the end, this kind of features is here just for convenience to be able to test quickly dirty legacy code.
