Problem running "rake spec" with Workling and Starling

Hi,

I installed Starling and Workling and set them up.
Then when I tried to run “rake spec”, it halts with a message
“config/starling.yml configured to connect to starling on
localhost:22122
for this environment. could not connect to starling on this host:port.
pass
starling the port with -p flag when starting it. If you don’t want to
use
Starling at all, then explicitly set Workling::Remote.dispatcher (see
README
for an example)”

But the port 22122 is set for development in config/starling.yml.

I tried to execute rake spec ENV[“RAILS_ENV”] = “test”
But the same result.

Does anybody know the reason why this happens and how to resolve it?

Thank you.
