(depot/test/integration/user_stories_test.rb，38行)
"
assert_equal 0, session[:cart].items.size

为什么这个测试能成功呢？保存 order 的 action 是这样处理的：
(depot/app/controllers/store_controller.rb，36-38行)
"
if @order.save
  session[:cart] = nil
  redirect_to_index(I18n.t('flash.thanks'))
"
按照道理保存 order 之后 session[:cart] 就是 nil 了，怎么可能还会有 session[:cart].items.size = 0 呢？
