Error of render

Rails
1

Hi
I test < render “home_simple”, :layout => “simple”>
response.should render_template(“home_simple”)

How can i test the < render “home” >
response.should render_template(“home”)

it gives me error as : expecting <“home”> but rendering with <"">.

def home
if !current_user
render “home_simple”, :layout => “simple”
else
render “home”
end
end

thanks for your help
