ruby-on-rails - RSpec - @controller 为零

Question

我有一个非常基本的 RoR 网站，需要开始为它编写一些 RSpec 测试。我有一个不需要登录用户的“关于”页面，它由我的 PagesController 控制。当从浏览器运行时，关于页面效果很好。我只是想简单地测试一下，有点像在 RoR 教程中。

我正在使用 Rails 3、RSpec 2.7.0、Windows

pages_controller.rb:

class PagesController < ApplicationController
    def about
    end
end

pages_controller_spec.rb:

require 'spec_helper'
describe "PagesController" do
    describe "GET 'about'" do
        render_views
        it "should be successful" do
            get 'about'
            response.should be_success
        end
    end
end

对于它的值(value)，这是我的 spec_helper.rb:

ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'rspec/autorun'
Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}
RSpec.configure do |config|
    config.include RSpec::Rails::ControllerExampleGroup
    config.mock_with :rspec
    config.fixture_path = "#{::Rails.root}/spec/fixtures"
    config.use_transactional_fixtures = true
    config.infer_base_class_for_anonymous_controllers = false
end

但是当我运行测试时，我得到:

Failures:

1) PagesController GET 'about' should be successful
  Failure/Error: get 'about'
   RuntimeError:
     @controller is nil: make sure you set it in your test's setup method.
     # ./spec/controllers/pages_controller_spec.rb:12:in `block (3 levels) in <top (required)>'

任何帮助表示赞赏。我知道这一定很容易!谢谢!!

尝试改变

describe "PagesController" do

到

describe PagesController do
