 Rails 3 allows you to alter what generators are used with the +config.generators+ method. This method takes a block:

-    g.test_framework :test_unit

 Besides these usual middleware, you can add your own by using the +config.middleware.use+ method:
 
 <ruby>
-  config.middleware.use Magical::Unicorns
+config.middleware.use Magical::Unicorns

 This will put the +Magical::Unicorns+ middleware on the end of the stack. If you wish to put this middleware before another use +insert_before+:
 
 <ruby>
-  config.middleware.insert_before ActionDispatch::Head, Magical::Unicorns
+config.middleware.insert_before ActionDispatch::Head, Magical::Unicorns

 <ruby>
-  config.middleware.insert_after ActionDispatch::Head, Magical::Unicorns
+config.middleware.insert_after ActionDispatch::Head, Magical::Unicorns
 </ruby>
 
 Middlewares can also be completely swapped out and replaced with others:
 
 <ruby>
-  config.middleware.swap ActionDispatch::BestStandardsSupport, Magical::Unicorns
+config.middleware.swap ActionDispatch::BestStandardsSupport, Magical::Unicorns

 They can also be removed from the stack completely:
 
 <ruby>
