Относно тестването на инициализации имам въпрос. Принципно инициализацията е нещо, което не връща някакъв резултат и няма външно от обекта действие. Как е редно да се тества? В случая аз ползвам други методи като to_s в случая с Version и to_a в случая с Range за да мога да видя дали инициализацията е коректна. Обаче по тоя начин обвързвам теста за един метод с другия и това не ме кефи много.

Това не ми харесва много, че ми се наложи да го правя, но смятам, че е хубаво да тествам сравнението за равенство, а ако използвам expect(something == something) Рубокопа се оплаква, че сравнявам нещо със същото нещо и не ми дава да си кача решението. По тоя начин го забаламосвам.

Не използвай before(:all), а само before (еквивалентно е на before(:each)). В този случай, ако нещо "счупи" обекта, той ще продължи да бъде счупен и в останалите тестове - тоест ще "протече" някакво състояние, което е лошо.

А още по-добре, направи го с let.
