lita bot not responding to triggers

Question

I/m using Lita to create a chatbot, I have created a handle called dialog to where and I've opted to separate my code, i have my chat routes in lita-dialog/lib/lita/handlers/dialog.rb and my responses in lita-dialog/bin/main.rb.

the code in lita-dialog/lib/lita/handlers/dialog

 module Lita
  module Handlers
    class Dialog < Handler
      # insert handler code here
       route(/.*hello|hi|good morning|morning|welcome.*/i, :greeting_response, command: true)
      Lita.register_handler(self)
    end
  end
end

the code in lita-dialog/bin/main.rb

require_relative '../lib/dialog.rb'

 def greeting_response(response)
    greetingresponse = [
      'Hello',
      "Greetings, #{response.user.name}.",
      "Well hello there, #{response.user.name}.",
      "Hey #{response.user.name}, Hello!",
      "Good day, #{response.user.name}",
      'Hi.'
    ]

    response.reply(greetingresponse.sample)
 end

I'm using RSpec to test my code and the test is passing but I when I test out the bot to get a response I don't receive and response which is not expected

Type "exit" or "quit" to end the session.                                                                                                          │<rive/Microverse/Ruby/jaybot   lita-dialog/spec/lita/handlers/dialog_spec.rb                         ruby     utf-8     16% ☰    1/6  :  1

tests

require "spec_helper"

describe Lita::Handlers::Dialog, lita_handler: true do
  it { is_expected.to(route_command('hello').to(:greeting_response)) }
  it { is_expected.to_not(route('hello').to(:greeting_response)) }
end

this is the output that I'm getting when i run the bot within the handler folder

The Lita handler you showed defines a route that will invoke an instance method called greeting_response when an incoming message matches. There is no instance method with that name defined, hence the "undefined method" exception. You have a method with this name defined in the other file, but a method defined at the top-level scope is not the same thing as an instance method in a class. If you want that method to be included in the Lita handler class, you should define it in a module that you include in the handler.
