Rails Tutorial static pages routes test red (5.28) - ruby-on-rails

Question

Doing Michael Hartl's Rails Tutorial, but stumped on Listing 5.28 (getting RED test instead of GREEN), changing the test to match the new routes.
ERRORS for all pages (/, /about, /contact, /help):
ActionController::UrlGenerationError: No route matches {:action=>"/*", :controller=>"static_pages"}
routes.rb
Rails.application.routes.draw do
root 'static_pages#home'
get '/help', to: 'static_pages#help'
get '/about', to: 'static_pages#about'
get '/contact', to: 'static_pages#contact'
end
tests/controllers/static_pages_controller_test.rb
require 'test_helper'
class StaticPagesControllerTest < ActionController::TestCase
test "should get home" do
get root_path
assert_response :success
assert_select "title", "Ruby on Rails Tutorial Sample App"
end
test "should get help" do
get help_path
assert_response :success
assert_select "title", "Help | Ruby on Rails Tutorial Sample App"
end
test "should get about" do
get about_path
assert_response :success
assert_select "title", "About | Ruby on Rails Tutorial Sample App"
end
test "should get contact" do
get contact_path
assert_response :success
assert_select "title", "Contact | Ruby on Rails Tutorial Sample App"
end
end
static_pages_controller.rb
class StaticPagesController < ApplicationController
def home
end
def help
end
def about
end
def contact
end
end
Let me know if you need to see any other code! Have tried adding as: '*' after each get route, but to no avail.
Not sure if it is a ruby/rails version issue, but I am using Rails 4.2.2 and Ruby 2.3.0 on an IDE, but "rails test" (as Hartl instructs to use) won't work (kicks back "test Command not found"). Not sure if that's a hint to a bigger problem or unrelated. Thanks in advance!
EDIT: Links using these paths (like below) are rendering correctly, it is just failing the tests.
<%= link_to "Home", root_path %>
<%= link_to "Help", help_path %>

Answer 1

Your test/controllers/static_pages_controller_test.rb have problem. I would suggest to replace it with below contents.
require 'test_helper'
class StaticPagesControllerTest < ActionDispatch::IntegrationTest
test "should get home" do
get root_path
assert_response :success
assert_select "title", "Ruby on Rails Tutorial Sample App"
end
test "should get help" do
get help_path
assert_response :success
assert_select "title", "Help | Ruby on Rails Tutorial Sample App"
end
test "should get about" do
get about_path
assert_response :success
assert_select "title", "About | Ruby on Rails Tutorial Sample App"
end
test "should get contact" do
get contact_path
assert_response :success
assert_select "title", "Contact | Ruby on Rails Tutorial Sample App"
end
end
Change the above file as I have suggested and run $ rails test you can see green test. I also suggest you to upgrade your app to rails 5.0.0 as Michael Hartl's have been upgraded his rails tutorials to rails 5.0.0 in future you have more things to learn and if you upgrade it, your journey of learning would be more error free and pleasant.
