За този метод необходимо ли е да тествам всички негови производни оператори? ( ==, >, <, >=, <=)
Да. Иначе няма как да си сигурен, че работят.
Адекватен начин ли е това да се провери дали не сме повредили инстанцията, след като сме й викнали #components?
Идеята не е да провериш
дали components поврежда инстанцията като се викне
, адали components може да се използва, за да се промени инстанцията
.Освен това,
object_id
-то на инстанцията никога няма да се промени. Каквото и да й правиш.Промени решението, така че да няма
dup
, зареди файла в едно irb и се опитай да пресъздадеш проблема. После го направи на тест.
