Error!

Hello I keep getting this error:

treehouse:~/projects/odot (master *) $ bin/rspec spec/features/todo_lists/edit_spec.rb

Failures:

  1) Editing todo lists updates a todo list successfully with correct information
     Failure/Error: update_todo_list todo_list: todo_list,

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

If you need more of the backtrace for any of these deprecations to
identify where to make the necessary changes, you can configure
`config.raise_errors_for_deprecations!`, and it will turn the
deprecation warnings into errors, giving you the full backtrace.

Regarding the depreciation warnings this post might help you out.

maybe this line:

expect(todo_list.title). eq("New title")

should be

expect(todo_list.title).to eq("New title")

    end

    #Title

Thank you so much, it takes another person to sometimes see an error, thank you once again!
