Question

我不能因为我的生活似乎以不会随时抛出随机错误的方式设置rspec / capybara。我最常见的错误（但不一致）如下：

An error occurred in an after hook
  ActiveRecord::RecordNotFound: Couldn't find Post with id=1
  occurred at [...]/gems/activerecord-3.2.11/lib/active_record/relation/finder_methods.rb:341:in `find_one'

紧随其后的是与期望在规范中创建的模型对象有关的任何事情，然后再找不到。例如

之类的东西

Sorter should populate featured_posts with appropriate posts
Failure/Error: Sorter.top_4.map(&:id).should eq(([best_new_post, best_old_post] + new_posts.last(2).reverse).map(&:id))

   expected: [2, 1, 40, 38]
        got: []

当我单独运行它们时，这些测试将始终通过，当我在套件中运行它们时，它们并不总是会失败。我假设线程存在某种问题以及如何设置数据库，但我似乎无法弄明白。

我的spec_helper.rb是各种来源的大杂烩：

require 'rubygems'
require 'spork'

Spork.prefork do
  ENV["RAILS_ENV"] ||= 'test'
  require File.expand_path("../../config/environment", __FILE__)
  require 'rspec/rails'
  require 'rspec/autorun'
  require 'capybara/rspec'
  require 'capybara/email/rspec'
  include ApplicationHelper

  Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}

  include Warden::Test::Helpers
  Warden.test_mode!

  ActionController::Base.asset_host = "http://localhost:3000"

  RSpec.configure do |config|
    config.include Rails.application.routes.url_helpers

    config.use_transactional_fixtures = false
    config.use_transactional_examples = false #factoryGirl

    # From http://railsapps.github.io/tutorial-rails-devise-rspec-cucumber.html
    config.before(:suite) do
      DatabaseCleaner.strategy = :truncation
      DatabaseCleaner.clean_with(:truncation)
    end
    config.before(:each) { DatabaseCleaner.start }
    config.after(:each) { DatabaseCleaner.clean }
    #

    config.infer_base_class_for_anonymous_controllers = false

    ## Setting up email helpers
    config.include MailerMacros
    config.before(:each) { reset_email }

    ## Setting up test and login helpers for Devise testing
    config.include Devise::TestHelpers, type: :controller
    config.extend ControllerMacros, type: :controller

    # From http://railscasts.com/episodes/413-fast-tests
    config.order = "random"

    config.include FactoryGirl::Syntax::Methods

    config.treat_symbols_as_metadata_keys_with_true_values = true
    config.filter_run focus: true
    config.run_all_when_everything_filtered = true

    config.filter_run_excluding :slow unless ENV["SLOW_SPECS"]

    config.before(:all) { DeferredGarbageCollection.start }
    config.after(:all) { DeferredGarbageCollection.reconsider }
  end
end

Spork.each_run do  
  Rails.cache.clear
  Warden.test_reset!
  FactoryGirl.reload
end

我已经尝试删除碎片进行故障排除，但由于错误是零星的，所以很难判断它是否解决了任何问题。

这里有什么突出显示上述错误的明显原因，或者有关如何解决此问题的任何建议？

在spec_helper.rb中，尝试设置

config.use_transactional_fixtures = true
