+## Задание 1: юнит-тесты
+Представь: нужно протестировать программу, которая помогает заказать бургер в Stellar Burgers. Тебе предстоит покрыть её юнит-тестами.  
+Здесь пригодятся моки, стабы и параметризация: где именно их использовать, реши самостоятельно.
+### Что нужно сделать
+Склонируй репозиторий с заготовкой кода.  
+Подключи библиотеки: Jacoco, Mockito, JUnit 4.  
+Покрой тестами классы Bun, Burger, Ingredient, IngredientType. Используй моки, стабы и параметризацию там, где нужно.  
+Процент покрытия должен быть не ниже 70%.
