Тук трябва да направиш още нещо, за да тестваш, че не променя версията. Можеш ли да се сетиш как може да се използва components, за да се промени обекта, ако нямаше dup в кода му?

В този си вид теста е безсмислен - очевидно е, че единствено с извикване на components няма да се промени версията.

Това изреждане на променливи не ми харесва особено. Сложи ги долу в expect-овете. Ще е по-очевидно какви версии тестваш.

Ако решиш да ги оставиш тук ще трябва да им дадеш по-добри имена от versionN, което не е лека задача.

Тук трябва да направиш още нещо, за да тестваш, че не променя версията. Можеш ли да се сетиш как може да се използва components, за да се промени обекта, ако нямаше dup в кода му?

В този си вид теста е безсмислен - очевидно е, че единствено с извикване на components няма да се промени версията.
