ActiveJob run enqueued jobs without block for testing.

test_job_helper.rb

# this pulls out each job and runs it, then clears the job queue.
# helpful when you don't want to run inside a block.
def perform_enqueued_jobs_now
  enqueued_jobs = ActiveJob::Base.queue_adapter.enqueued_jobs

  enqueued_jobs.each do |item|
    item[:job].perform_now(*item[:args])
    ActiveJob::Base.queue_adapter.performed_jobs << item
  end

  ActiveJob::Base.queue_adapter.enqueued_jobs.clear
end

FYI this won't work if you have jobs that are serialized with GlobalID.
