Question

我已升级到Rails 3.1，一切似乎都运行正常。但是测试（RSpec）无论如何都会失败，例如以下一个：

describe "for admin user" do

  before(:each) do
    @city = Factory(:city)
    @user = Factory(:user)
    @business = Factory(:business, :user_id => @user.id, 
                        :city_id => @city.id)
    @admin = test_sign_in(Factory(:user, :email => "admin@example.it", 
                                  :admin => true))
  end

  it "should have an edit link for all businesses in show city" do
    get :show, :id => @city
    response.should have_selector('a',
      :href => "/businesses/#{@business.id}-Factory-business-city-Factory-business/edit")
  end
end

这适用于Rails 3.0.8，但现在测试失败了。测试日志说：

[1m [35mSQL（0.2ms）[0m INSERT INTO users（admin，created_at，email，encrypted_password，name ，salt，updated_at）VALUES（1，'2011-09-21 10:30:30'，'admin @ example.it'，'68f8a34e0243a642662fe2b6ea8ed7c714d042750a66ce542f2df288caefac32'，'管理员名称'，'6df34c304d79437d495e60d2d34e1028489731afa96690efbc25c714224edb1f' ，'2011-09-21 10:30:30'）

CitiesController处理#show as HTML [1m [35mUser Load（0.2ms）[0m SELECT users。* FROM users WHERE users。id IS NULL LIMIT 1

[1m [36mCity负荷（0.2ms）[0m [1mSELECT cities。* FROM cities WHERE cities。id = 942 LIMIT 1 [0m

[1m [35mCity Load（0.2ms）[0m SELECT cities。* FROM cities WHERE cities。id = 942 LIMIT 1

[1m [36mCity负荷（0.2ms）[0m [1mSELECT cities。* FROM cities WHERE cities。id = 942 LIMIT 1 [0m

[1m [36mUser Load（0.2ms）[0m [1mSELECT users。* FROM users WHERE users。id IS NULL LIMIT 1 [0m

因此，似乎没有用户ID（NULL），但管理员之前已正确创建。这可能是一个cookie问题吗？

我的Gemfile中的测试组是：

group :test do
  gem 'rspec', '2.6.0'
  gem 'rspec-rails', '2.6.1'
  gem 'webrat', '0.7.3'
  gem 'factory_girl_rails', '1.0'
  gem 'spork', '~> 0.9.0.rc'
end

我的test.rb是

Project::Application.configure do
  # Settings specified here will take precedence over those in config/application.rb

  # The test environment is used exclusively to run your application's
  # test suite.  You never need to work with it otherwise.  Remember that
  # your test database is "scratch space" for the test suite and is wiped
  # and recreated between test runs.  Don't rely on the data there!
  config.cache_classes = true

  # Configure static asset server for tests with Cache-Control for performance
  config.serve_static_assets = true
  config.static_cache_control = "public, max-age=3600"

  # Log error messages when you accidentally call methods on nil
  config.whiny_nils = true

  # Show full error reports and disable caching
  config.consider_all_requests_local       = true
  config.action_controller.perform_caching = false

  # Raise exceptions instead of rendering exception templates
  config.action_dispatch.show_exceptions = false

  # Disable request forgery protection in test environment
  config.action_controller.allow_forgery_protection    = false

  # Tell Action Mailer not to deliver emails to the real world.
  # The :test delivery method accumulates sent emails in the
  # ActionMailer::Base.deliveries array.
  config.action_mailer.delivery_method = :test

  # Use SQL instead of Active Record's schema dumper when creating the test database.
  # This is necessary if your schema can't be completely dumped by the schema dumper,
  # like if you have constraints or database-specific column types
  # config.active_record.schema_format = :sql

  # Print deprecation notices to the stderr
  config.active_support.deprecation = :stderr

  # Allow pass debug_assets=true as a query parameter to load pages with unpackaged assets
  config.assets.allow_debugging = true
end

这是我的spec_helper：

# This file is copied to spec/ when you run 'rails generate rspec:install'
require 'rubygems'
require 'spork'

Spork.prefork do
  # Loading more in this block will cause your tests to run faster. However, 
  # if you change any configuration or code from libraries loaded here, you'll
  # need to restart spork for it take effect.
  ENV["RAILS_ENV"] ||= 'test'
  unless defined?(Rails)
    require File.dirname(__FILE__) + "/../config/environment"
  end
  require 'rspec/rails'

  # Requires supporting files with custom matchers and macros, etc,
  # in ./support/ and its subdirectories.
  Dir["#{File.dirname(__FILE__)}/support/**/*.rb"].each {|f| require f}

  Rspec.configure do |config|
    # == Mock Framework
    #
    # If you prefer to use mocha, flexmock or RR, uncomment the appropriate line:
    #
    # config.mock_with :mocha
    # config.mock_with :flexmock
    # config.mock_with :rr
    config.mock_with :rspec

    config.fixture_path = "#{::Rails.root}/spec/fixtures"

    # If you're not using ActiveRecord, or you'd prefer not to run each of your
    # examples within a transaction, comment the following line or assign false
    # instead of true.
    config.use_transactional_fixtures = true

    ### Part of a Spork hack. See http://bit.ly/arY19y
    # Emulate initializer set_clear_dependencies_hook in 
    # railties/lib/rails/application/bootstrap.rb
    ActiveSupport::Dependencies.clear

    def test_sign_in(user)
      controller.sign_in(user)
    end
  end
end

Spork.each_run do
end

感谢您的建议/答案！

通过以下问题可以解决问题：

Cookies do not persist in Rspec on rails 3.1

不是一个完美的方式，但它会起作用！

升级到Rails 3.1后，许多带有测试sign_in的rspec测试失败，可能是cookie问题？
