Benchmarker controller action


I am trying to use script/performance/benchmarker to test a controller

I have tested different ways of specifying the action e.g for
controller account, action test
‘AccountController.test’, ‘account_controller.test’ etc but nothing
seems to work.
I know how to made my own benchmark within the action, but would like
to use the benchmarker

Is that possible ?
How do you specify the action in using this script ?
