Question

我使用RSpec和Capybara编写了一个简单的测试。

我的失败规格是 sign_in_feature_spec.rb：

require 'spec_helper'

describe 'the signin process', :type => :feature do
  it 'signs me in' do
    admin_user = FactoryGirl.create(:admin_user)
    login_as(admin_user, :scope => :admin_user)
    visit root_path
    puts page.body
  end
end

当我运行此规范时，我会看到下一个报告：

1例，0次失败，1次传递

所以，测试成功了，但我从puts page.body得到了这个输出：

NoMethodError at /
==================

> undefined method `saved_filters' for #<AdminUser:0x00000009abf870>

activemodel (4.1.9) lib/active_model/attribute_methods.rb, line 435
-------------------------------------------------------------------

``` ruby
  430       def method_missing(method, *args, &block)
  431         if respond_to_without_attributes?(method, true)
  432           super
  433         else
  434           match = match_attribute_method?(method.to_s)
> 435           match ? attribute_missing(match, *args, &block) : super
  436         end
  437       end
  438   
  439       # +attribute_missing+ is like +method_missing+, but for attributes. When
  440       # +method_missing+ is called we check to see if there is a matching

导致此回溯的原因是什么？测试环境配置有问题吗？当我切换到ENV["RAILS_ENV"] ||= 'development'时，问题仍然存在，但是如果我在开发中运行应用程序，则一切正常，在auth之后我会看到正确的页面。
