ruby1.8升级到1.9.2后执行“ Test::Unit::UI::Console::TestRunner.run(eval(caseClassName))”语句报错。报错信息：
c:/Ruby192/lib/ruby/gems/1.9.1/gems/ci_reporter-1.6.5/lib/ci/reporter/test_unit.rb:68:in `initialize': uninitialized constant Test::Unit::TestCase::STARTED (NameError)

test-unit版本为：2.5.3
此问题折磨了好几天了，哪位知道能否指点一下，不胜感谢

网上查了下，有说"Ruby 1.9 用新的单元测试框架MiniTest替换了1.8版本中的Test：：Unit测试框架"。应该是这个原因导致的，但是不知道如何解决此问题
