我是一名不熟悉Ruby on Rails并尝试使用TDD开发Rails 4应用程序的高中生。我正在使用警卫以及rspec，spork和growl通知，但是当我运行后卫来运行我的测试时，我得到以下输出并且测试没有结果：

如果我只是独立于后卫运行rspec，我的测试运行正常并显示输出：
13 clairehuang:mezzo$ rspec

Deprecation Warnings:
RSpec::Core::Configuration#treat_symbols_as_metadata_keys_with_true_values= is deprecated, it is now set to true as default and setting it to false has no effect.
If you need more of the backtrace for any of these deprecations to
identify where to make the necessary changes, you can configure
`config.raise_errors_for_deprecations!`, and it will turn the
deprecation warnings into errors, giving you the full backtrace.

如何让我的测试与后卫一起运行？非常感谢你提前！
