ruby-on-rails - 使用 Rspec、NiftyAuthentication 进行测试

Question

我正在使用 Ryan Bates 的 nifty:authentication ，并开始使用 Rspec 进行测试。与这个斗争了几个星期，仍然不明白发生了什么。

我的 Controller 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，但每次测试都失败。无论我尝试什么，我都会得到 redirect_to login_url, :alert => "You must first ...log in"页。

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。如何使我的登录正常工作？

我按照 Punit 的建议进行了尝试:
[预]

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 vanilla 规范而不是 Controller 规范，这意味着未设置变量“ Controller ”。

要使用 Controller 规范，您需要将 Controller 类名称而不是字符串传递给您的 describe 块。

describe MyController do

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

一旦你这样做了，你应该能够使用你原来的想法来 stub login_required
