モデルに次のようなage
メソッドがあります。Waiver
def age(date = nil)
if date.nil?
date = Date.today
end
age = 0
unless date_of_birth.nil?
age = date.year - date_of_birth.year
age -= 1 if date < date_of_birth + age.years #for days before birthday
end
return age
end
次に、次のような仕様があります。
it "calculates the proper age" do
waiver = FactoryGirl.create(:waiver, date_of_birth: 12.years.ago)
waiver.age.should == 12
end
この仕様を実行すると、comparison of Date with ActiveSupport::TimeWithZone failed
. 私は何を間違っていますか?
Failures:
1) Waiver calculates the proper age
Failure/Error: waiver.age.should == 12
ArgumentError:
comparison of Date with ActiveSupport::TimeWithZone failed
