我正在尝试将Rails应用程序升级到Rails3。
运行功能测试时，会出现很多NameError: uninitialized constant Test::Unit::AssertionFailedError错误。但是单元测试和网站本身似乎可以正常工作。
跟踪看起来像这样:
NameError: uninitialized constant Test::Unit::AssertionFailedError

Shoulda和Amazon S3 gem 都是最新版本。
有什么想法我做错了吗？
最佳答案
据报道http://github.com/thoughtbot/shoulda/issues/issue/117。
解决方法(至少使该错误消失，不确定它是否正确运行)是:
unless defined?(Test::Unit::AssertionFailedError)
class Test::Unit::AssertionFailedError < ActiveSupport::TestCase::Assertion
end
end
