Question

我正在使用rails中的rspec测试模型（control.rb），我遇到了日期时间问题。它没有成功，因为我期望和我得到的差异为00001000000000。这是我的代码

describe ".graphic_data_for_all_days" do
  before do
    Timecop.freeze(DateTime.now)
  end

  after do
    Timecop.return
  end

it "the controls are ordered from older to newer" do
    # time = DateTime.now.to_i
    # DateTime.stub!(:now).and_return{DateTime.at(time += 5) }
    control = FactoryGirl.create(
      :control, 
      user: user, 
      level: 120,
      day: Timecop.freeze(DateTime.now)
      )
    control2 = Control.create(
      user_id: user.id, 
      level: 106, 
      period: "pre-breakfast", 
      day: Timecop.freeze(DateTime.now + 3.hours)
      )
    control3 = Control.create(
      user_id: user.id, 
      level: 104, 
      period: "pre-breakfast", 
      day: Timecop.freeze(DateTime.now + 6.hours)
      )
    control4 = Control.create(
      user_id: user.id, 
      level: 104, 
      period: "pre-breakfast", 
      day: Timecop.freeze(DateTime.now + 9.hours)
      )
     graphic_data_for_all_days = Control.graphic_data_for_all_days(user.id)
     expect(graphic_data_for_all_days).to eq ([{
      name: "day", 
      data:[
        [Timecop.freeze(DateTime.now).strftime("%I:%M%p").to_time.utc.to_i * 1000, 120],
        [(Timecop.freeze(DateTime.now + 3.hours)).strftime("%I:%M%p").to_time.utc.to_i * 1000, 106],
        [(Timecop.freeze(DateTime.now + 6.hours)).strftime("%I:%M%p").to_time.utc.to_i * 1000, 104],
        [(Timecop.freeze(DateTime.now + 9.hours)).strftime("%I:%M%p").to_time.utc.to_i * 1000, 104] 
        ]
        }])
  end

这是config / environments / test.rb

        config.after_initialize do
  # Set Time.now to September 1, 2008 10:05:00 AM (at this instant), but allow it to move forward
      t = DateTime.now
      Timecop.travel(t)
      end

这就是控制台让我回来的原因

    expected: [{:name=>"day", :data=>[[1418881560000, 120], [1418892360000, 106], [1418913960000, 104], [1418946360000, 104]]}]
            got: [{:name=>"day", :data=>[[1418899560000, 120], [1418910360000, 106], [1418931960000, 104]]}, {:name=>"day", :data=>[[1418877960000, 104]]}]

我不知道如何通过测试。如果有人能帮助我，我会感谢你。
