 Созданы юнит-тесты, покрывающие классы `Bun`, `Burger`, `Ingredient`, `Database`
 
-Процент покрытия 100% (отчет: `htmlcov/index.html`)
+Процент покрытия 100% (без main()) (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.
 
+## Тесты
+
+Тесты покрывают все классы и используют:  
+- `pytest` для запуска  
+- `pytest-mock` для моков объектов (`Bun`, `Ingredient`)  
+- параметризацию (`@pytest.mark.parametrize`) для тестирования нескольких сценариев  
+
+
 ### Запуск автотестов
 
 **Установка зависимостей**
