我有一个相当简单的 rails 应用程序，基于 railstutorial.org 教程的前半部分。我有点头疼... Capybara 似乎没有访问我要访问的页面。我想确保用户在看到products#index操作之前已登录。我有“未登录”测试通过，但“登录”测试在应该通过时仍然失败。
这是我的产品页面规范：
require 'spec_helper'
describe "Product pages" do
subject { page }
describe "index" do
context "when not signed in" do
before { visit products_path }
it { should have_title 'Sign in' }
end
context "when signed in" do
let(:user) { FactoryGirl.create(:user) }
before do
sign_in user
visit products_path
end
it { should have_title('Listing all products') }
end
end
end
第一个测试通过，但第二个没有。使用一些试验和错误我能够弄清楚它会进入主页（如果我把主页的标题放在should have_title()它通过）
我对 RSpec 很陌生，但是几乎相同的 user_pages_spec 测试工作正常：
require 'spec_helper'
describe "User pages" do
subject { page }
describe "index" do
let(:user) { FactoryGirl.create(:user) }
before do
sign_in user
visit users_path
end
it { should have_title('All users') }
it { should have_content('All users') }
end
end
是什么导致一个失败而一个通过？有没有办法让 rspec 吐出更多关于正在发生的事情的信息？
这是我的gemfile，如果有帮助的话：
source 'https://rubygems.org'
ruby '2.0.0'
#ruby-gemset=micmanager
gem 'rails', '4.0.1'
gem 'pg', '0.15.1'
gem 'bootstrap-sass-rails'

group :doc do
gem 'sdoc', '0.3.20', require: false
end
group :production do
gem 'rails_12factor', '0.0.2'
end
任何帮助是极大的赞赏！我发现的唯一这样的问题是：Capybara 访问方法不起作用，这根本没有任何帮助。
谢谢！

产品控制器：
class ProductsController < ApplicationController
before_action :set_product, only: [:show, :edit, :update, :destroy]
before_action :signed_in_user
before_action :admin_user, only: [:index, :new, :edit, :update, :destroy]
# GET /products
# GET /products.json
def index
@products = Product.all
end
end
before_action提到的s 在sessions_helper文件中：
module SessionsHelper
def sign_in(user)
remember_token = User.new_remember_token
cookies.permanent[:remember_token] = remember_token
user.update_attribute(:remember_token, User.encrypt(remember_token))
self.current_user = user
end
def signed_in?
!current_user.nil?
end
def sign_out
self.current_user = nil
cookies.delete(:remember_token)
end
def current_user=(user)
@current_user = user
end
def current_user
remember_token = User.encrypt(cookies[:remember_token])
@current_user ||= User.find_by(remember_token: remember_token)
end
def current_user?(user)
user == current_user
end
def redirect_back_or(default)
redirect_to(session[:return_to] || default)
session.delete(:return_to)
end
def store_location
session[:return_to] = request.url if request.get?
end
def signed_in_user
unless signed_in?
store_location
redirect_to signin_url, notice: "Please sign in."
end
end
def correct_user
@user = User.find(params[:id])
redirect_to root_url unless current_user?(@user)
end
def admin_user
redirect_to root_url unless current_user.admin?
end
end
....发布所有这些后，我想通了...我将答案粘贴在下面。彼得·戈德斯坦（Peter Goldstein）提到了“过滤器”，因为这就是问题所在……
