Testing Rails root route

Now I need to test a root route in a Rails App

Step 1. Learning the routing file

File: config/routes.rb

Rails.application.routes.draw do
  root to: 'root#index'
end

Step 2. Adding a test

File: spec/routing/root_spec.rb. This time I didn't use describe, only it.

root_path is a Rails routing helper that is equal to /.

require 'rails_helper'

RSpec.describe 'Root Route', type: :routing do
  it 'leads to a correct controller and action' do
    get(root_path).should route_to("root#index")
  end

  it 'does not exist' do
    expect(post: root_path).not_to be_routable
  end
end

Step 3. Running the spec

bundle exec rspec spec/routing/root_spec.rb --format documentation

That is it!
Happy coding!
