rspec failure upon revisit

I just returned from a different project after taking a few weeks off of
my tutorial. I'm using Ruby on Rails 3 Tutorial - Learn Rails by
Example by Michael Hartl.

After rebooting my server I ran an rspec spec/ command to check to see
if there were any problems and this is what I received. I didn't modify
anything except I did overwrite users_controller.rb and
users_controller_spec.rb when starting another chapter of the tutorial.
I'm not sure what changed.

I'm having trouble diagnosing the error:

  UsersHelper add some examples to (or delete)
    # No reason given
    # ./spec/helpers/users_helper_spec.rb:14
  User add some examples to (or delete)
    # No reason given
    # ./spec/models/user_spec.rb:4
  users/new.html.erb add some examples to (or delete)
    # No reason given
    # ./spec/views/users/new.html.erb_spec.rb:4

Failed examples:

rspec ./spec/requests/layout_links_spec.rb:25 # LayoutLinks should have
a signup page at '/signup'

Is this something I can fix? Looks to be searching for a signup page
that doesn't exist (?).

Please reply if you have a chance. Thanks, Andrew

I found the issue was case sensitive 'Sign up' v. 'Sign Up'

Looks like your spec is expecting a different tag than the one you’ve got here.
