Rails性能测试"rake test:benchmark"和"rake test:profile"给我错误

Question

我正在尝试使用Ruby 1.9和Rails 2.3.5运行一个空白的默认性能测试,但我无法让它工作!我在这里失踪了什么？

rails testapp
cd testapp
script/generate scaffold User name:string
rake db:migrate
rake test:benchmark

好吧,问题是ruby 1.8使用Test :: Unit作为其默认测试库.在ruby 1.9中,改为MiniTest.

3.1.0之前的ActiveSupport版本假设为Test :: Unit.看起来它已在3.1.0及更高版本中得到解决.如果您使用的是rails 3.0.9,它依赖于activesupport 3.0.9,因此您无法在Gemfile中请求更高版本.

通过Google 找到了这个.显然,Test :: Unit库仍然可用,但作为名为'test-unit'的gem.

所以在rails gem之前的顶部我的Gemfile中,我把:

gem 'test-unit', '~> 2.3.0'

然后我跑了rake测试:基准测试,它工作了!
