我正在尝试设置我的Rails 3.2应用程序的cloud9（https://c9.io）测试安装，以便新开发人员可以快速启动并运行以提交更改和运行测试。我的所有测试都通过了，但是它们与许多与不同宝石相关的警告混合在一起：
Loaded suite /usr/local/rvm/gems/ruby-2.1.2/gems/rake-11.1.1/lib/rake/rake_test_loader Started ......

......它继续并为许多其他宝石生成警告。
在我自己的Ubuntu / Debian机器上，我没有看到这些警告，并且很难看到现在穿插在其他几十个警告线中的测试结果。
有没有办法抑制警告或配置我的测试，以便它们不会触发这种级别的冗长？

此处有不同环境的选项：Suppress Ruby warnings when running specs
我使用RUBYOPT=W0 rake test，这适用于带有RVM的（crouton，ARM）Ubuntu 14系统。
