Hi everyon, Thank you for your help! I did the controller test, but there is a problem when run the test. Controller.rb: def change\_password user = current\_user if User.authenticate(user.login, params[:old\_password]) if (params[:password] == params[:password\_confirmation]) user.password\_confirmation = params[:password\_confirmation] user.password = params[:password] if user.save result = \_(“Password changed!”) reset\_current\_user(user.id) else (“Could not save change, please try again.”) end else result = \_(“Your passwords do not match.”) @old\_password = params[:old\_password] end else result = \_(“Your old password is incorrect.”) end end the controller\_test.rb: def test\_should\_allow\_password\_change post :change\_password, { :old\_password =\> ‘123’, :password =\> ‘newpassword’, :password\_confirmation =\> ‘newpassword’}, {:user\_id=\>users(:user1).id} assert\_equal ‘newpassword’, assigns(:user).password end when I run this test, There always said, NoMetodError: You have a ni object when you didn’t expect it: the error occurred while evaluating nil.password. I have try to use: assert\_equal ‘newpassword’, assigns(‘user’).password assert\_equal ‘newpassword’, assigns[:user].password assert\_equal ‘newpassword’, assigns[‘user’].password but there is same problem. I don’t know why? Please help1 Thanks! ---

You don’t have a data item in your fixture’d database called ‘user’, only ‘user1’ and ‘user2’ Try assert\_equal ‘newpassword’, assigns(:user1).password ---
