Данная лабораторная работа посвещена изучению фреймворков для тестирования на примере GTest
$ open https://github.com/google/googletest- 1. Создать публичный репозиторий с названием lab05 на сервисе GitHub
- 2. Выполнить инструкцию учебного материала
- 3. Ознакомиться со ссылками учебного материала
- 4. Составить отчет и отправить ссылку личным сообщением в Slack
