Chapter 7 Ruby on Rails users_controller.rb error

Question

I followed all the instructions in chapter 7 Ruby on Rails tutorial, when I finally run $ Bundle exec rspec spec/ a series of errors are being displayed. I doubled checked if my codes had any spelling mistakes or any symbols left out. Everything seems to fine. Could you please kindly interpret the errors and tell me where I am going wrong??? Thanks

Answer 1

1) undefined method full_title

Are you defined it?

2) expected css "title" with text "Michael Hartl" to return something

You haven't <title>Michael Hartl</title> in output html.

3, 4) undefined method sign_in

Where are you defined it?

Correct your code and all tests will be passed.
