黄瓜配timecop

Question

我正在尝试同时使用cucumber和timecop，它的timecop似乎没有覆盖我的transaction.rb模型文件中的Time.now调用。

以下是我的场景：

  @stop @wip
  Scenario: Displaying defaults when entering a form
    Given I am on the new transaction page
    And the time is Dec 31 2010, 9:00 UTC
    Then the "Tran date" field should contain "31/12/2010"

我在一个timecop_steps.rb文件中包含了这些步骤

Given 'the time is $time' do |time|
  Timecop.freeze Time.parse(time)
end

When '$time pass' do |time|
  Timecop.travel future_time(time)
  Given 'delayed jobs are run' # we use delayed jobs and have some that get scheduled in the future.
end

When 'time stands still' do
  Timecop.freeze Time.now
end

然后在我的transaction.rb文件中设置我的默认值：

class Transaction < ActiveRecord::Base
  def set_defaults
    self.tran_date = Time.now.strftime("%d/%m/%Y")
  end
end

当我运行我的场景时，我得到了以下结果：

  Scenario: Displaying defaults when entering a form   # features/receipt_journal_new.feature:29
    Given I am on the new transaction page
                         # features/step_definitions/web_steps.rb:45
    And the time is Dec 31 2010, 9:00 UTC                              # features/step_definitions/timecop_steps.rb:1
    Then the "Tran date" field should contain "31/12/2010"             # features/step_definitions/web_steps.rb:142
      expected: /31\/12\/2010/
           got: "20/07/2011" (using =~)
      Diff:
      @@ -1,2 +1,2 @@
      -/31\/12\/2010/
      +20/07/2011
       (RSpec::Expectations::ExpectationNotMetError)
      ./features/step_definitions/web_steps.rb:147:in `block (2 levels) in <top (required)>'
      ./features/step_definitions/web_steps.rb:30:in `with_scope'
      ./features/step_definitions/web_steps.rb:143:in `/^the "([^"]*)" field(?: within (.*))? should contain "([^"]*)"$/'
      features/transaction_new.feature:32:in `Then the "Tran date" field should contain "31/12/2010"'

更新：

我甚至尝试过清除Time.now，但也不起作用：

Given 'the time is $time' do |time|
  Time.stub!(:now).and_return("31/12/2010") #Time.parse(time))
#  Timecop.freeze Time.parse(time)
end

Update2：

我已经尝试使用chronic以及使用Timecop.travel代替Timecop.freeze，如本文所示：

Update3：

我在我的rspec模型测试中测试了Timecop，它工作得很好。

Answer 1

答案很简单，就是我在我的场景中设置Timecop的顺序

Given the time is Dec 31 2010, 9:00 UTC
And I am on the new transaction page
