Rspec any_instance存根導致錯誤未定義的方法__rspec_original_dup

我試圖爲該類的任何實例（通過any_instance）剔除一個類方法。我的測試成功運行，但在測試結束時，當rspec試圖重置any_instance存根時，它會引發錯誤（無法從回溯中找到匹配的行）。這是明顯的罪魁禍首代碼行（刪除它刪除錯誤）：Rspec any_instance存根導致錯誤未定義的方法__rspec_original_dup

Confetti::Config.any_instance.stub(:write_info)

完整的錯誤如下。看起來像存根應該（但未能）創建__rspec_original_dup方法，並且當重置發生時，它找不到預期的方法。

看起來像您使用的是OSX系統Ruby。如果您使用RVM或rbenv，它可以工作嗎？我問，因爲我們看到相同的行爲，但只適用於運行OSX系統Ruby的開發人員。 – bobocopy 2012-07-30 22:07:35

升級到RSpec 2.11後得到類似的東西。我使用RVM的Ruby 1.9.3，儘管在OS X上，如果它有任何相關性的話。我執行'ThinkingSphinx :: Search.any_instance.stub（：error）'並在backtrace中使用'/ Users/henrik /'來獲取類'\ ThinkingSphinx :: Search''的錯誤'undefined method \'dup'。 rvm/gems/[email protected]/gems/rspec-mocks-2.11.1/lib/rspec/mocks/any_instance.rb：64：在'alias_method'中。 – 2012-07-31 14:46:15

創建問題：https：//github.com/rspec/rspec-mocks/issues/168 – 2012-07-31 16:51:57

我解決了這個簡單使用Rspec的v2.10.0代替v2.11.0的：

gem 'rspec', '~> 2.10.0'

從這個亨裏克提供的鏈接，這聽起來像他們可能會釋放一個Rspec的修正錯誤。有關更多信息，請參閱this issue。與此同時，降級解決了我的問題。

（感謝您幫助我解決這個問題的工作，Henrik。）
