мой юнит-тест:

  end

  test "product attributes must not be empty" do

Answer 1

Я не могу понять вашу проблему.Потому что вы не используете какие-либо setup,teardown методы в приведенном выше коде.Укажите полный тестовый пример или просто проверьте, что методы setup и teardown имеют аргументы операции.Проблема, связанная только с этим.
