Лабораторная работа №6

Рефакторинг программного кода

Студента ИТ14-1 Красовского Абхая

Цель работы: научиться выполнять реорганизацию программного кода на основании шаблонов рефакторинга.

Ход выполнения работы

Выполнить анализ программного кода разрабатываемого ПО и модульных тестов с целью выявления плохо организованного кода.
Используя шаблоны рефакторинга, выполнить реорганизацию программного кода разрабатываемого ПО.
Выполнить описание произведенных операций рефакторинга (было-стало-шаблон рефакторинга).
В случае необходимости скорректировать проектную документацию (диаграммы классов, последовательностей).
Сделать выводы по результатам выполнения работы.
