(urgent) Testing Controller of Rails

Hi,

I am a new comer of testing on rails .

I am trying to testing my controller, and read a lot of testing using rspec and shoulda.

can anyone give me some examples about those rspec.

cuz sometime i did not understand how to use rspec for the controller.

def create

@user = User.new(params[:user])

@user.is_admin = false

@user.enabled = false

if @user.save

redirect_to :action => “confirm”

else

@cultures = Culture.where(:enabled => true)

@languages = Language.where(:enabled => true)

render “new”

end

end

def show

redirect_to :action => “edit”

end

if my controller like that… how can i test by using rspec… please help
