Hartl Ruby on Rails Tutorial - Chapter 8 failed test

I am currently working on Michael Hartl's Ruby on Rails tutorial. I've been getting 4 separate errors during this chapter and would greatly appreciate your help with resolving them.

$ bundle exec rake test

I made a mess..ugh. Any and all help is much appreciated!

Edit: Also, i'm fairly new to all this, so if I'm supposed to be deleting the old tests as they test GREEN, please let me know. I'm not sure if these failed tests go RED because I'm doing something wrong or if I'm supposed to be deleting them as I go through the tutorial. Thank you!

Answer 1

In your routes.rb

get 'login'   => 'sessions#new'
get 'login'   => 'sessions#create'

that looks weird. I guess it should be

get 'login'   => 'sessions#new'
post 'login'  => 'sessions#create'
