这是minitest，链轮轨道，还是红宝石2的bug ?

Question

我想修补spprocketsrails中的一个bug，但是当我运行测试套件(使用ruby-2.0.0-p0以及ruby-head)时，我得到了以下错误:

/Users/btaitelb/.rvm/rubies/ruby-head/lib/ruby/2.1.0/test/unit.rb:707:in `block in _prepare_run': undefined method `size' for #<ParallelEach:0x007f823aa55e88> (NoMethodError)

    from /Users/btaitelb/.rvm/rubies/ruby-head/bin/testrb:7:in `<main>'

我不清楚Test::Unit和MiniTest之间的关系，特别是因为我看到了Test/Unit。rb引用MiniTest::Unit

我可以用几种方式修补这个问题，但我不确定哪个项目是罪魁祸首(例如，我应该在哪里提交补丁):

1. 在测试/单位。在ruby中，我可以用对count的调用替换对size的调用，但这似乎只有在Test::Unit期望ParallelEach成为测试套件
的一部分时才合适。
2. 在minitest中，我可以别名count到size，这是有意义的，如果minitest负责将ParallelEach对象发送到Test::Unit

这两个是合适的，还是有其他的事情发生(比如命名冲突)?

这原来是minitest中的一个bug，已经修复了:https://github.com/seattlerb/minitest/pull/275
