Question

我将Rails堆栈从4.2.x升级到5.0.1。此堆栈没有数据库支持的模型。使用rspec作为测试框架。测试在4.2.x环境中运行，但不在5.0.1分支中运行。

未加载active_model / railtie
config.active_record.dump_schema_after_migration已注释掉
的ActiveRecord :: Migration.maintain_test_schema！被注释掉了
config.use_transactional_fixtures和config.fixture_path已注释掉
factory_girl和其他灯具/工厂工具不存在

尽管如上所述，rspec仍试图加载灯具并最终引发异常（下面的堆栈跟踪），因为ActiveRecord没有连接池。有什么建议要检查以纠正这个问题吗？

的Gemfile：

gem 'rack-cors'
gem 'oauth2'

gem 'activemodel-serializers-xml'
gem 'draper', '~> 3.0.0.pre1'
gem 'aws-sdk', '~> 1.61.0'
gem 'newrelic_rpm'
gem 'skylight', '= 1.0.0'
gem 'actionpack-page_caching', '~> 1.1.0'
gem 'redis'
gem 'sneakers'

group :development do
  gem 'better_errors'
  gem 'binding_of_caller'
  gem 'meta_request'
  gem 'brakeman'
  gem 'redis-rails-instrumentation'
end

group :development, :test do
  gem 'dotenv-rails'
  gem 'rspec-rails'
  gem 'listen'
end

group :test do
  gem 'selenium-webdriver'
  gem 'capybara'
  gem 'faker'
  gem 'launchy'
  gem 'codeclimate-test-reporter', require: nil
  gem 'mock_redis'
  gem 'simplecov'
end

供将来参考：我添加了'activemodel-serializers-xml'来恢复在Rails 5.01中提取但是最新生产版本的draper所需的一些功能。那个gem依赖于ActiveRecord（嗯，也许它应该是ActiveModel顾名思义？！）。更新到draper 3.0.0.pre1允许我删除'activemodel-serializers-xml'，并且规格都是绿色的。：）

当没有使用activerecord时，rspec试图加载灯具？
