我正在使用 Ryan Bates nifty:authentication，并开始使用 Rspec 进行测试。与此斗争了数周，但仍然不明白发生了什么。

我的控制器只是调用

before_filter :login_required, :except => [:login]

在 lib/controller_authentication 中定义

def self.included(controller)
    controller.send :helper_method, :current_account, :logged_in?, :redirect_to_target_or_default
  end

  def current_account
    @current_account ||= Account.find(session[:account_id]) if session[:account_id]
  end

  def logged_in?
    current_account
  end

  def login_required
    unless logged_in?
      store_target_location
      redirect_to login_url, :alert => "You must first answer me these riddles three log in or sign up before accessing this page."
    end
  end

  def redirect_to_target_or_default(default, *args)
    redirect_to(session[:return_to] || default, *args)
    session[:return_to] = nil
  end

  private

  def store_target_location
    session[:return_to] = request.url
  end
end

该应用程序按预期工作，但测试每次都失败。无论我尝试什么，我都会得到redirect_to login_url, :alert => "You must first ...log in"页面。

我尝试过的事情：

controller.stub!( :login_required )
ControllerAuthentication.stub!(:current_account).and_return(Account.where(:username => 'ej0c').first)
#ControllerAuthentication.stub!(:logged_in?).and_return(Account.where(:username => 'ej0c').first)
ControllerAuthentication.stub!(:login_required).and_return(true)
MyDigisController.stub!( :login_required ).and_return(true)

我认为这意味着我错过了整个理论。我怎样才能使我的登录工作？

我按照 Punit 的建议进行了尝试：[pre]

require 'spec_helper'

describe "View event details" do

  it "Should show a table of events" do
     @account = Account.where(:username => 'ej0c').first
     puts @account.inspect
     controller.stub!(:current_account).and_return(@account)
     controller.stub!(:logged_in?).and_return(true)
     session[:account_id] = @account.id
      visit '/my_digis/66/custom_events'
      page.should have_content('Events')

  end
end

@account.inspect 显示得很好，但我也得到了

An expectation of :current_account was set on nil. Called from C:/Users/Ed/webapps/whendidji3/spec/con
.rb:8:in `block (2 levels) in <top (required)>'. Use allow_message_expectations_on_nil to disable warn
An expectation of :logged_in? was set on nil. Called from C:/Users/Ed/webapps/whendidji3/spec/controll
:in `block (2 levels) in <top (required)>'. Use allow_message_expectations_on_nil to disable warnings.

感谢您提供任何详细的解释，因为我已经搜索了高低以了解发生了什么。

您使用的是普通规范而不是控制器规范，这意味着未设置变量“控制器”。

要使用控制器规范，您需要将控制器类名称传递给您的描述块而不是字符串。

describe MyController do

见http://rspec.info/rails/writing/controllers.html

一旦你这样做了，你应该能够使用你最初的想法存根 login_required

您需要存根“current_account”方法。你可以这样做 -

@account = create_account #function to create an account for your specs
controller.stub!(:current_account).and_return(@account)
controller.stub!(:logged_in?).and_return(true)

您可能应该从上述行中创建一个方法，以便在需要时对身份验证进行存根验证。

OK, the answer was that I needed a request spec.

I'd begun with a request spec, but it wasn't in the requests folder, and the questions I asked got it morphed into a half-request/half-controller spec, none of which works.

The strange thing about rspec is that it will complain if a capybara method is badly formed,...but it won't mention that the thing just plain doesn't work where you put it!

My working spec, located in specs/requests/my_digis_spec.rb is 

require 'spec_helper'

describe "MyDigis" do

   before :each do
@account = Account.where(:username => 'me').first
visit login_path
    fill_in 'Username or Email Address', :with => @account.email
    fill_in 'Password', :with => 'password'
  click_button('Log in')

end

it "Shows list of digis" do
  visit my_digis_path
  page.should have_content('Your Custom Event groups')
end

it "Lets you modify didji list" do
  visit my_digis_path
  click_button('Modify events')
  page.should have_content('Events for my_digi')
end

end

As easy as advertised, just took me 5 weeks to get the login part. Thanks.
