اصول تست واحد (ویرایش روسی)

Юнит-тестирование — это процесс проверки отдельных модулей программы на корректность работы. Правильный подход к тестированию позволит максимизировать качество и скорость разработки проекта. Некачественные тесты, наоборот, могут нанести вред: нарушить работоспособность кода, увеличить количество ошибок, растянуть сроки и затраты. Грамотное внедрение юнит-тестирования — хорошее решение для развития проекта. Научитесь разрабатывать тесты профессионального уровня, без ошибок автоматизировать процессы тестирования, а также интегрировать тестирование в жизненный цикл приложения. Со временем вы овладеете особым чутьем, присущим специалистам по тестированию. Как ни удивительно, практика написания хороших тестов способствует созданию более качественного кода. В этой книге: - Универсальные рекомендации по оценке тестов. - Тестирование для выявления и исключения антипаттернов. - Рефакторинг тестов вместе с рабочим кодом. - Использование интеграционных тестов для проверки всей системы.
