Question

我正在尝试为类的任何实例（通过any_instance）存根Class方法。我的测试成功运行，但在测试结束时，当rspec尝试重置any_instance存根时，它会抛出一个错误（无法从backtrace中找到匹配的行）。这是明显的罪魁祸首代码行（删除它会删除错误）：

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

完整错误如下。看起来像stub应该（但没有）创建__rspec_original_dup方法，并且当重置发生时，它找不到预期的方法。

我通过简单地使用Rspec v2.10.0而不是v2.11.0解决了这个问题：

gem 'rspec', '~> 2.10.0'

从Henrik提供的链接中，听起来他们可能会发布Rspec的错误修复程序。有关详细信息，请观看this issue。与此同时，降级为我解决了这个问题。

（感谢您帮助我解决这个问题的工作，Henrik。）
