undefined local variable or method `root_path' Hartl's Tutorial Chapter 5.3.2

Question

So my first question on Stackoverflow..... =]

My tests in Chapter 5.3.2 of Michael Hartl\'s RoR Tutorial are all failing, when the tutorial says it should be passing

Answer 1

  root :to => 'static_pages#home' 
  match '/help',    to: 'static_pages#help',    via: 'get'
  match '/about',   to: 'static_pages#about',   via: 'get'
  match '/contact', to: 'static_pages#contact', via: 'get'

works for me

test results: 9 examples 0 failures

urls seem to have changed like this now:

http://localhost:3000/about
