我正在尝试将我的 rails 应用程序升级到 Rails3。

当我运行功能测试时，我会遇到很多NameError: uninitialized constant Test::Unit::AssertionFailedError错误。但是单元测试和网站本身似乎工作正常。

跟踪看起来像这样：

NameError: uninitialized constant Test::Unit::AssertionFailedError
/Users/mantas/.rvm/gems/ruby-1.9.2-p0/gems/aws-s3-0.6.2/lib/aws/s3/extensions.rb:206:in `const_missing_from_s3_library'
/Users/mantas/.rvm/gems/ruby-1.9.2-p0/bundler/gems/shoulda-02520e4/lib/shoulda/action_controller/matchers/redirect_to_matcher.rb:52:in `rescue in redirects_to_url?'

Shoulda 和 Amazon S3 gem 都是最新版本。

任何想法我做错了什么？

Ash Berlin 的解决方案将使异常消失，但它会使任何匹配器try失败catch Test::Unit::AssertionFailedError。如果AssertionFailedError是一个ActiveSupport::TestCase::Assertion，而你抛出一个ActiveSupport::TestCase::Assertion，你不会把它当成一个Test::Unit::AssertionFailedError。他的继承关系倒退了。相反，把它放在你的test_helper.rb：

unless defined?(Test::Unit::AssertionFailedError)
  Test::Unit::AssertionFailedError = ActiveSupport::TestCase::Assertion
end

这已报告http://github.com/thoughtbot/shoulda/issues/issue/117。

解决方法（至少使这个错误消失，不确定它是否真的有效）是：

unless defined?(Test::Unit::AssertionFailedError)
  class Test::Unit::AssertionFailedError < ActiveSupport::TestCase::Assertion
  end
end
