По принцип няма да тестваме с такъв случай, затова ще си позволя да ти споделя потенциален проблем. Ако ключалката не очаква никакви аргументи, `self.lock_args` ще ти остане недефинирано и после влизаш в безкраен цикъл. Пак да кажа - не е нужно да го оправяш, защото няма да тестваме за празна ключалка.
