纠正 gem，mongo，测试 ActiveRecord::ConnectionNotEstablished

Question

添加 rectify gem 后，所有测试都失败并出现错误：

ActiveRecord::ConnectionNotEstablished:
 No connection pool for ActiveRecord::Base

我们正在使用：
宝石：

• Rails 4.2.8
• Mongoid 5
• 修正 0.9.1
• Rspec 3.4.4

另一个：

• 操作系统：Ubuntu 16.04LTE
• MongoDB：3.4.3
• 由 docker-compose 运行的数据库。
• docker-compose 版本 1.12.0

进入开发模式一切正常。

看起来测试数据库配置中有一些简单的错误，但我不知道究竟是什么。
任何帮助将不胜感激。谢谢！
