When I use rspec: Invalid route name, already in use: 'root' (ArgumentError)

Question

When I use rspec to do some testing: bundle exec rspec spec/ terminal throws this error to me. But in my route.rb, I think I only define one root path

Answer 1

These two named routes:

match '/signin',  to: 'sessions#new',         via: 'get'  
match '/signout', to: 'sessions#destroy',     via: 'delete'

are overriding the routes set up with:

resources :sessions, only: [:new, :create, :destroy] 

Change that line to:

resources :sessions, only: [:create] 

assuming that you even need that route.
