configure Shoryuken with potentially mocked SQS

shoryuken.rb

# initialize moto SQS queue for dev environment
if Rails.env.development?
  sqs = Aws::SQS::Client.new(
    access_key_id: ENV["AWS_ACCESS_KEY_ID"],
    region: ENV["AWS_REGION"],
    endpoint: "http://localhost:4576/",
    secret_access_key: ENV["AWS_SECRET_ACCESS_KEY"],
    verify_checksums: false
  )

  begin
    ENV["PARSED_QUEUE_NAME"] = sqs.create_queue(queue_name: ENV['SQS_QUEUE_NAME']).queue_url
  rescue Seahorse::Client::NetworkingError => e
    puts "Unable to connect to SQS to create dev queue"
  end
end

# Rely on ENV["PARSED_QUEUE_NAME"] throughout rest of application
ENV["PARSED_QUEUE_NAME"] ||= ENV['SQS_QUEUE_NAME']
Shoryuken::EnvironmentLoader.setup_options(config_file: 'config/shoryuken.yml')
