Testing subdomains as account keys

Hello,

I'm just starting to write tests for my apps (I've really been putting
it off). Im trying to test the following code but I'm getting an error
"undefined local variable or method `current_account'" in a functional
test.

My codes is @ https://gist.github.com/62b19d8e8d26e392a4b4

Basically, how can I get access to the current_account method in my
functional test?

Thanks

I think I've got it now. I'm now calling @controller.send
(:current_account) rather than current_account. I'm using send because
the method is private.
