ruby - Rails 3 + Devise + Rspec - Controller 测试中的未定义方法错误

Question

我有这样的规范 (spec/controllers/stats_controller_spec.rb) 来测试我的 Controller :

require 'spec_helper'

describe StatsController do
  render_views

  before(:each){ @user = FactoryGirl.create( :user ) }

  describe "GET 'users_in_system'" do
    describe "for non-signed users" do
      it "should deny access" do
        get :users_in_system, :locale => :en
        #...
      end
    end
  end
end

当我运行这个规范时，我得到这样的错误:

1) StatsController GET 'users_in_system' for non-signed users should deny access
     Failure/Error: get :users_in_system, :locale => :en
     ActionView::Template::Error:
       undefined method `authenticate' for nil:NilClass
     # ./app/views/layouts/_navbar_template.html.haml:16:in `_app_views_layouts__navbar_template_html_haml__2938837959272005060_70149962955560'
     # ./app/views/layouts/application.html.haml:12:in `_app_views_layouts_application_html_haml__243298846079092947_70149956982200'
     # ./spec/controllers/stats_controller_spec.rb:12:in `block (4 levels) in <top (required)>'

我试图通过将此行添加到 (spec/spec_helper.rb) 来解决此错误:

#...

RSpec.configure do |config|
  config.include Devise::TestHelpers, :type => :controller
  #...
end

然后我开始出现这样的错误:

1) StatsController GET 'users_in_system' for non-signed users should deny access
     Failure/Error: Unable to find matching line from backtrace
     NoMethodError:
       undefined method `env' for nil:NilClass

我试图添加 (spec/controllers/stats_controller_spec.rb):

describe StatsController do
  render_views
  include Devise::TestHelpers
  #...
end

但这并没有改变什么。我该如何修复它？

更新:我的统计 Controller :

class StatsController < ApplicationController
  def users_in_system
    @users = User.all
  end
end

我的导航栏:

%div{ :class => "navbar navbar-inverse navbar-fixed-top" }
  %div{ :class => "navbar-inner" }
    %a{:class => "btn btn-navbar", "data-toggle" => "collapse", "data-target" => ".nav-collapse"}
      %span{:class=>"icon-bar"}
      %span{:class=>"icon-bar"}
      %span{:class=>"icon-bar"}

    = link_to t(".brand_name"), root_path, { :class => "brand" }
    %div{ :class => "nav-collapse" }
      -# Left navigation.
      %ul{ :class => "nav" }
        %li=link_to "About", about_path

      -# Right navigation.
      %ul{ :class => "nav pull-right" }
        - if user_signed_in?
          %li=link_to t(".settings"), edit_user_registration_path
          %li{ :class => "divider-vertical" }
          %li=link_to t(".logout_link"), destroy_user_session_path, :method => :delete

Answer 1

你的回溯看起来你正在使用 rspec-rails 2.10.0 有 this issue设置回调顺序。尝试将该特定 gem 的版本升级到 2.10.1，因为它应该已修复。

你走在正确的道路上

RSpec.configure do |config|
  config.include Devise::TestHelpers, :type => :controller
  #...
end

所以我认为您可以从您的规范文件中删除显式 include Devise::TestHelpers。
