Quick unit test customer safety. This way I'm not overwriting data by accident.

customer_update_info_test.rb

def setup
   @cus_save = Customer.find("####")
   login
end
	
def teardown
   cus = Customer.find "####"
				
   cus.attributes = @cus_save.attributes
   assert cus.save!
end
	
def login
   post_via_redirect "authenticate/login", :username => @cus_save[:cus_login], :password => @cus_save[:cus_password]
   assert_equal "/", path
   assert_equal @cus_save.id, session[:id]
		
   get_via_redirect "customer/update_info"   
   assert_equal "/customer/update_info", path
end
