 ### Реализованные сценарии
 
-Созданы юнит-тесты, покрывающие классы `Bun`, `Burger`, `Ingredient`, `Database`
+Созданы юнит-тесты, покрывающие класс `Burger`
 
 Процент покрытия 100% (отчет: `htmlcov/index.html`)
 
 ### Структура проекта
 
 - `praktikum` - пакет, содержащий код программы
-- `tests` - пакет, содержащий тесты, разделенные по классам. Например, `bun_test.py`, `burger_test.py` и т.д.
