[Solved] Deprecation warnings Devise::TestHelpers

Another entry in the series of 'notes to myself' here.
A simple fix for the Deprecation warning saying that Devise::TestHelpers will be removed.
The fix is to replace the

 config.include Devise::Test::Helpers, :type => :controller  

with

config.include Devise::Test::ControllerHelpers, :type => :controller  

in spec/rails_helper.rb.
Unlike many of the suggested solutions, I don't have the devise configuration in the rails_helper file.
I have a separate set of helper functions, and the relevant location is 

spec/support/devise.rb.

 RSpec.configure do |config|  
  config.include Devise::Test::ControllerHelpers, :type => :controller  
 end  

You can stop reading now and go do something more productive instead.

RSpec failing after a new Rails Composer project

RSpec issues

Add
require 'rails_helper.rb'
into the spec files to allow the tests to run as expected.

spec/features/visitors/sign_up_spec.rb

The minimum password length is set to be 6 characters, but the 'expected fail' password was set to 'please', causing the test to fail.

Changed password to 'short' and test passes.

spec/features/users/sign_in_spec.rb

The tests were looking for an authentication_key of 'email'. Changed to 'Email' to match the results from Devise.

Getting Puma to listen for all hosts with the Guardfile

This has been bugging me for a while, and I've finally had time to track down how to configure Guardfile in order to have Puma listen to all ip addresses.

guard 'rails', :host => '0.0.0.0' do
  watch('Gemfile.lock')
  watch(%r{^(config|lib)/.*})
end

Adding the :host => '0.0.0.0' gets puma to listen for all addresses.
