運行Rake加載它的測試套件？

在某些時候，我開始在運行rake任務時獲得測試輸出，我不知道爲什麼。運行Rake加載它的測試套件？

$ rake -T 
(task output) 
Loaded suite /Users/tsigo/.rbenv/versions/1.9.2-p290/bin/rake 
Started 

Finished in 0.000398 seconds. 

0 tests, 0 assertions, 0 failures, 0 errors, 0 skips 

Test run options: --seed 30951

而且rails c是古怪的行爲，以及：

$ rails c 
Loading development environment (Rails 3.1.6) 
irb(main):002:0> Rails.version 
=> "3.1.6" 
irb(main):003:0> RUBY_VERSION

/Users/tsigo/.rbenv/versions/1.9.2-p290/lib/ruby/1.9.1/minitest/unit.rb:581:in `block in process_args': invalid option: --rubygems (OptionParser::InvalidOption) 
    from /Users/tsigo/.rbenv/versions/1.9.2-p290/lib/ruby/1.9.1/minitest/unit.rb:560:in `new'

    from /Users/tsigo/.rbenv/versions/1.9.2-p290/lib/ruby/1.9.1/minitest/unit.rb:508:in `block in autorun'

最後，在我的RSpec套件，如果有一個失敗，它不顯示文件和行信息，使得任何輸出幾乎沒用：
