2 tests fail at chapter 10.2.1 end: No route matches - ruby-on-rails

Question

I'm having problems while trying to pass the test at the end of section 10.2.1 of Michael Hartl's Rails Tutorial book at the current state of the art. In particular, when I uncomment the before_action line in app/controllers/users_controller.rb according to listing 10.21 and then run the test suite as to the subsequent listing 10.22 (where the tests should be green), two tests are failing, namely test_should_redirect_edit_when_not_logged_in and test_should_redirect_update_when_not_logged_in. It looks very strange to me since I succeeded all the steps until this point :\
Anyway, here's the error code:
ERROR["test_should_redirect_edit_when_not_logged_in", UsersControllerTest, 1.0972138489887584]
test_should_redirect_edit_when_not_logged_in#UsersControllerTest (1.10s)
ActionController::UrlGenerationError: ActionController::UrlGenerationError: No route matches {:action=>"edit", :controller=>"users", :id=>nil} missing required keys: [:id]
test/controllers/users_controller_test.rb:10:in `block in <class:UsersControllerTest>'
ERROR["test_should_redirect_update_when_not_logged_in", UsersControllerTest, 1.1339553739962867]
test_should_redirect_update_when_not_logged_in#UsersControllerTest (1.13s)
ActionController::UrlGenerationError: ActionController::UrlGenerationError: No route matches {:action=>"show", :controller=>"users", :id=>nil} missing required keys: [:id]
test/controllers/users_controller_test.rb:16:in `block in <class:UsersControllerTest>'
But according to rake routes the routes above are already there!
Prefix Verb URI Pattern Controller#Action
edit_user GET /users/:id/edit(.:format) users#edit
user GET /users/:id(.:format) users#show
Here's my app/controllers/users_controller.rb:
class UsersController < ApplicationController
before_action :logged_in_user, only: [:edit, :update]
def show
#user = User.find(params[:id])
end
def new
#user = User.new
end
def create
#user = User.new(user_params)
if #user.save
log_in #user
flash[:success] = "Welcome to the Sample App!"
redirect_to #user
else
render 'new'
end
end
def edit
#user = User.find(params[:id])
end
def update
#user = User.find(params[:id])
if #user.update_attributes(user_params)
flash[:success] = "Profile updated"
redirect_to #user
else
render 'edit'
end
end
private
def user_params
params.require(:user).permit(:name, :email, :password,
:password_confirmation)
end
# Before filters
# Confirms a logged-in user.
def logged_in_user
unless logged_in?
flash[:danger] = "Please log in."
redirect_to login_url
end
end
end
my test/controllers/users_controller_test.rb:
require 'test_helper'
class UsersControllerTest < ActionDispatch::IntegrationTest
test "should get new" do
get signup_path
assert_response :success
end
test "should redirect edit when not logged in" do
get edit_user_path(#user)
assert_not flash.empty?
assert_redirected_to login_url
end
test "should redirect update when not logged in" do
patch user_path(#user), params: { user: { name: #user.name,
email: #user.email } }
assert_not flash.empty?
assert_redirected_to login_url
end
end
and my config/routes.rb:
Rails.application.routes.draw do
get 'sessions/new'
root 'static_pages#home'
get '/help', to: 'static_pages#help'
get '/about', to: 'static_pages#about'
get '/contact', to: 'static_pages#contact'
get '/signup', to: 'users#new'
post '/signup', to: 'users#create'
get '/login', to: 'sessions#new'
post '/login', to: 'sessions#create'
delete '/logout', to: 'sessions#destroy'
resources :users
end
Hope some bold heroes will help! :) Thanks a lot in advance

test "should redirect edit when not logged in" do
get edit_user_path(#user)
#user is nil. This is what causes the error. I guess you skipped over a small snippet of code.
