I was with him half way through the tape. Now I am getting this error message. I don't know where I have gone wrong.

Deprecation Warnings:

--------------------------------------------------------------------------------
RSpec::Core::ExampleGroup#example is deprecated and will be removed
in RSpec 3. There are a few options for what you can use instead:

  - rspec-core's DSL methods (`it`, `before`, `after`, `let`, `subject`, etc)
    now yield the example as a block argument, and that is the recommended
    way to access the current example from those contexts.
  - The current example is now exposed via `RSpec.current_example`,
    which is accessible from any context.
  - If you can't update the code at this call site (e.g. because it is in
    an extension gem), you can use this snippet to continue making this
    method available in RSpec 2.99 and RSpec 3:

      RSpec.configure do |c|
        c.expose_current_running_example_as :example
      end

You don't need to paste in the deprecation messages, it's just to tell you that you're using an older version of rSpec. Not a problem. The video is a bit old. The error is this:

-> Completing todo items is successful when marking a single item complete Failure/Error: visittodo_list todo_list ActionView::Template::
Error: undefined method completed?' for #<TodoItem:0xb948a170>

-> Completing todo items with completed items shows completed items as complete Failure/Error: visittodo_list todo_list ActionView::Template::
Error: undefined method completed?' for #<TodoItem:0xb9724e6c> 

-> Completing todo items with completed items does not give the option to mark complete Failure/Error: visittodo_list todo_list ActionView::Template::

# A typo in the completed? method perhaps
Error: undefined method completed?' for #<TodoItem:0xb97532d0>

See the error? It's a typo.

I'm guessing from the error messages, that you've made a typo in your completed? method. You might have called it 'completed' without a question mark, or something like that. Try to check that in your code. If you cannot fix it, paste the complete_spec.rb file, and we'll see if something can't be done. Sounds good? Hope this helps.

Will have look later. Thanks for the reply as I have been racking my brains about this.
