unique_job_worker.rb

# -*- encoding : utf-8 -*-
require_relative 'logging_helper'

class UniqueJobWorker
  include Sidekiq::Worker
  include WorkerHelper
  sidekiq_options retry: false,
                  backtrace: true,
                  queue: :sender,
                  failures: true

  def perform(worker,campaign_guid, queue)
    require'pry';binding.pry
  end
end

unique_job_worker_test.rb

require 'test_helper'
require 'mocha/setup'

class UniqueJobWorkerTest < ActiveSupport::TestCase
  def setup
    require'pry';binding.pry
    @worker = UniqueJobWorker.new
  end
  
  test "it exists" do
    assert @worker
  end
end

When enqueued through redis I get this response

INFO -- : Exception: uninitialized constant UniqueJobWorker

Any suggestions as to why my newly created worker, UniqueJobWorker, is not being found during runtime through redis or through a simple test?

Thanks ahead of time!

When you use sidekiq outside of Rails, you need to use the -r option to tell it how to load your workers. So (assuming that your worker is in a sub-directory called workers):
```
% sidekiq -r ./workers/unique_job_worker.rb
```
If you have multiple workers, an option is to create a loader file to ensure everything is loaded.

load_workers.rb
```
($LOAD_PATH << 'workers').uniq!
require 'unique_job_worker'
require 'other_worker'
...
```
Then require the loader file on the command line:
```
% sidekiq -r ./load_workers.rb
```

I had the same issue and ended up being a Redis namespace issue:

https://github.com/mperham/sidekiq/issues/2834#issuecomment-184800981

Adding that fixed it for me:
```
config.redis = {
    url: ENV['REDIS_URL'],
    namespace: "some_namespace_different_for_each_app"
}
```
You also need the redis-namespace gem BTW
