黄瓜步骤：如何从不同的步骤获取输入数据？

Question

我有这种情况：

Given I am on the edit_stamp page
And I change the date to "14.5.2010"              #<-- i need this data
...
Then I should see that the new times has been set #<-- down here

我基本上更新模型的日期，在最后一步中，我想验证模型是否确实更新了我在第一步中选择的日期。

如何在最后一步定义中从顶部抓取所选日期？

Then(/^I should see that the new times has been set$/) do
  s = Stamp.first
  find_by_id("day_date#{s.id}").has_text?("14.5.2010")
end

这就是我现在所拥有的，但我不想将日期（14.5.2010）写入步骤定义，我想从上一步中获取它。

试试这个：

And (/^I change the date to "(.*?)"$/) do |input_date|
  @new_date = input_date
  # and here do whatever you are doing with the date
end

Then(/^I should see that the new times has been set$/) do
  s = Stamp.first
  s.date_or_whatever_attribute_you_are_using.to_s.should == @new_date
end

这些实例变量（@xx）与整个场景一起存在。
