Имаш два варианта тук:

  1. Правиш описанията по-добри от it compares versions
  2. Махаш context-а и слагаш трите примера в един it, и го кръщаваш it 'compares versions with equal length'

В момента ако четеш лога ще видиш "compares versions and returns true" и "compares versions and returns false", които си противоречат.

Ами този тест го направих за да проверя дали version.components.object_id != version.components.object_id, което се очаква, но по много глупав начин. Иначе, ако метода променя вътрешно състоянието и връща копие, то теста ще фейлне, защото не проверява за този случай.

Първият път като го четох съм го разбрал погрешно. Обърка ме dup-а, който правиш. Затова тестовете трябва да са много очевидни. Сравни твоето решение с това:

version.components.push 10
