+# Курс Яндекс Практикум "Инженер по тестированию: от новичка до автоматизатора"
+## Диплом. Задание 1. Юнит-тесты
+
+### Технологии проекта:
+Java 11, Maven 3.9.0, Jacoco 0.8.13, JUnit 4.13.2, Mockito 5.19.0, Assertj 3.27.6
+
+### Как запускать:
+`mvn clean test`
+
+### Описание проекта:
+Протестирована программа Stellar Burgers, которая помогает собрать свой бургер и сделать заказ.
+
+- собран Maven-проект в IntelliJ IDEA с использованием Java 11 и подключением библиотек JUnit 4, Jacoco, Mockito;
+- покрыт юнит-тестами класс Burger;
+- применены параметризация и моки;
+- сгенерирован отчет с помощью Jacoco для оценки покрытия кода тестами.
