rspec - Ubuntu에서만이 속성 비교 usng assert_equal이 실패 할 때 왜 실패합니까?

Question

두 가지 테스트가 실패했습니다. 우분투에서만 (12), 내 (새) Mac에서는 테스트가 아닙니다.

실패한 두 가지는 Active Record 개체 속성 비교이지만이를 비교하기 위해 노력하고 있습니다. 명령 줄에서 해시를 만들고 특성을 붙여 넣으면 비교 결과가 동일하다고 말합니다.

우리는 수 백 가지의 테스트가 포함 된 광범위한 테스트 스위트를 보유하고 있기 때문에 진정한 난제입니다. 레일 3.2.8, RSpec에 2.11

i=0 
while i < @student.attributes.count 
    assert_equal @student.attributes[i], Student.first.attributes[i] 
    i+= 1
