Test

This is actuall Test contract

If you don't know what Test contracts are please read: https://blog.eq8.eu/article/explicit-contracts-for-rails-http-api-usecase.html

#config/environments/test.rb

Rails.application.configure do
  # ...
  config.x.bulkgate_sms_gateway_contract = 'BulkgateSmsGatewayContract::Mock'
  # ...
end

Example RSpec usage:

require 'rails_helper'
RSpec.describe 'sending of SMS' do
  def trigger
    BulkgateSmsGatewayContract.contract.send_sms(
      country: "sk",
      number: 908111222,
      body: "Your 2FA code is 1234")
   end

  it do
    expect(trigger).to eq "Bulkgate: Your 2FA code is 1234 TO: sk:908111222"
  end
end

Development

Will log SMS codes to log/sms.log

#config/environments/development.rb

Rails.application.configure do
  # ...
  config.x.bulkgate_sms_gateway_contract = 'BulkgateSmsGatewayContract::FileLog'
  # ...
end

Bonus - Production with Airbrake Debugging

If you are using Airbrake you can use for production debugging AirbrakeNotify contract

# config/environments/production.rb


# This contract is not loaded by default. You need to explicitly require it
require 'sms_gateway_contract/airbrake_notify'

# ...
  config.x.bulkgate_sms_gateway_contract = 'BulkgateSmsGatewayContract::AirbrakeNotify'
# ...

BulkgateSmsGatewayContract::AirbrakeNotify is only for debugging production. It's more a lazy tool to save cost during develompment. Don't use it once live.
