Testing -rspec Hartl Tutorial Chapter 8.2 - ruby-on-rails

Question

I've been having trouble trying to get my test to pass. I think the issue is with my signin_path, but I can't figure out where exactly the problem is, any help would be greatly appreciated!
Here is the Failure message (it's long. sorry about that):

I haven't figured out how to get HTML to post, but if it would be helpful to see the applicaiton.html.erb and the _header.html.erb, just let me know and I will keep trying. Any thoughts would be greatly appreciated! thanks!

Answer 1

The last method in your SessionsHelper module, current_user, doesn't need to take an argument user. This is why you see the error "wrong number of arguments (0 for 1)."
