rake_test_loader.rb - 堆棧級別太深

Question

`--> rake test 
Coverage report generated for Unit Tests to /home/chris-kun/code/thirsty/coverage. 0/0 LOC (0.0%) covered. 
/usr/lib/ruby/gems/1.9.1/gems/rake-0.9.2/lib/rake/rake_test_loader.rb:9: stack level too deep (SystemStackError) 
rake aborted! 
Command failed with status (1): [/usr/bin/ruby -I"lib:test" -I"/usr/lib/rub...] 

Tasks: TOP => test 
(See full trace by running task with --trace) 

我只是不確定如何處理上述問題。我應該從哪裏開始尋找問題？

更新： 因此，當我嘗試從我的單元測試的幫助器文件中加載環境時，似乎會觸發該錯誤。 （見https://github.com/thumblemonks/riot/issues/45）

UPDATE： 堆棧跟蹤：

同樣的事情發生在我身上。你在使用代碼覆蓋工具嗎？你在哪裏把require？是否在非常第一行的測試文件？
