有人可以提供故障排除提示吗？：
使用以下一系列与rails相关的命令：
rails new test6
bundle install
rails generate Controller Gohere left right up down
rake test
...似乎两次运行rake任务'test'。我哪里出错？
日志在这里：

答案 0 :(得分：11)
我意识到这篇文章已经很老了，但如果你从来没想过，或者别人对此感到困惑（就像我今晚一样），这就是发生了什么：
实际上有两套测试在这里运行：功能测试＆amp;单元测试。当你在一个像这样的新Rails项目中生成一个控制器时，你会得到一些功能测试，并且你得到一个没有实际测试的存根单元测试文件。
所以，你看到第一个测试结果：
0 tests, 0 assertions, 0 failures, 0 errors, 0 skips
是空单元测试文件的结果。
只要您填写一些单元测试，它就会显示非零结果。请注意，您还可以运行 rake test：units 或 rake test：functionals 来运行一组测试。
我希望有更明确的输出来表明发生了什么。 令人困惑。
