Автоматизирано (unit) тестване
12.04.2009

== Disclaimer ==

Днес няма да си говорим за acceptance testing, quality assurance или нещо, което се прави от "по-низшия" отдел във фирмата. Всичко тук е дело на програмиста.

== Митът ==
Проектът идва с готово, подробно задание. Прави се дизайн. С него работата се разбива на малки задачи. Те се извършват последователно. За всяка от тях пишете кода и приключвате. Изискванията не се променят, нито се добавя нова функционалност.
