Поскольку стратегия в системе обратного тестирования обычно рассчитана как бесконечный цикл,onexit()Невозможно запустить функцию, реализованную в стратегии выполнения, в системе обратного тестирования.onexit()функция может быть активирована путем обнаружения конечной марки системы обратного тестирования (исключение EOF).
