Question

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，我会收到很多NameError: uninitialized constant Test::Unit::AssertionFailedError错误。但单元测试和网站本身似乎工作正常。

Trace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'

Shoulda和Amazon S3宝石都是最新版本。

任何想法我做错了什么？

Answer 1

据报道http://github.com/thoughtbot/shoulda/issues/issue/117。

解决方法（至少会让这个错误消失，不确定实际是否正常）是：

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

Answer 2

Ash Berlin的解决方案将使例外消失，但它会使try和catch Test::Unit::AssertionFailedError失败的任何匹配器。如果AssertionFailedError是ActiveSupport::TestCase::Assertion，而您抛出ActiveSupport::TestCase::Assertion，则不会将其视为Test::Unit::AssertionFailedError。他的继承关系倒退了。相反，请将其放在test_helper.rb：

中

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

NameError：升级到rails3时未初始化的常量Test :: Unit :: AssertionFailedError
