You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: scheduled_jobs_test.rb
    path of file: ./repos/workarea/core/test/lib/workarea
    
    the code of the file until where you have to start completion: require 'test_helper'

module Workarea
  class 
    
    def test_remove_dead_jobs_after_initialize
      Sidekiq.logger.log_at(:error) do
        Sidekiq::Cron::Job.create(name: 'Foo', klass: 'Bar', cron: '1 * * * *')

        assert_includes(Workarea.redis.keys('cron_job:*'), 'cron_job:Foo')
        refute_nil(Sidekiq::Cron::Job.find('Foo'))

        ScheduledJobs.clean

        refute_includes(Workarea.redis.keys('cron_job:*'), 'cron_job:Foo')
        assert_nil(Sidekiq::Cron::Job.find('Foo'))
      end
    end
