测试单元与 ruby 2.2.0 不兼容吗？
Is test-unit incompatible with ruby 2.2.0?
我真的是 ruby 的新手。我开始按照 this 设置 ruby 指南进行游戏，rvm，将我所有的 mac 更新到当前版本，没有任何问题。所以我安装了 test-unit gem 并尝试了一些 TDD 脚本。 运行 测试没有任何反应。所以我 运行 ruby 使用“-d”选项，这就发生了。

可能是什么问题？
版本:
- Ruby：2.2.0p0（2014-12-25 修订版 49005）[x86_64-darwin14]
- Rvm: 1.26.10
- Gem: 2.4.6
编辑：我已经降级到 2.0.0 版并且工作正常。所以测试单元 gem 不是为当前 ruby 版本制作的？
直到 2.1，Ruby 随 test/unit 一起提供，但从 2.2 开始，它已被删除。
它仍然可用 gem：https://github.com/test-unit/test-unit/。来自自述文件："Test::Unit 1.2.3 is the original Test::Unit, taken straight from the ruby distribution. It is being distributed as a gem to allow tool builders to use it as a stand-alone package. (The test framework in ruby is going to radically change very soon)."
如果您确定测试单元 gem 已安装（gem install test-unit 或将 gem 'test-unit' 添加到您的 Gemfile）它应该可以解决问题。
