или по-добре, изкарай една променлива за range-а и използвай .to_not include вместо .to be false

В другия метод ако не се внимава - може да се промени обектът. Тук няма реална опасност да стане това. Не се връща нищо свързано със състоянието на версията.

Просто няма логика някога това да се счупи. Иначе, предполагам не би тествал дали <, >, <=, >=, ==, <=>, Version::Range.new и всички останали методи променят обекта. Защо тогава да тестваш само този?
