rails/activejob/CHANGELOG.md

• Add :only option to assert_enqueued_jobs

  With the option, assert_enqueued_jobs will check the number of times a specific kind of job is enqueued:

  def test_logging_job assert_enqueued_jobs 1, only: LoggingJob do LoggingJob.perform_later HelloJob.perform_later('jeremy') end end

• ActiveJob::Base.deserialize delegates to the job class

  Since ActiveJob::Base#deserialize can be overridden by subclasses (like ActiveJob::Base#serialize) this allows jobs to attach arbitrary metadata when they get serialized and read it back when they get performed. Example:

  class DeliverWebhookJob < ActiveJob::Base def serialize super.merge('attempt_number' => (@attempt_number || 0) + 1) end

   def deserialize(job_data)
     super
     @attempt_number = job_data['attempt_number']
   end
  
   rescue_from(TimeoutError) do |exception|
     raise exception if @attempt_number > 5
     retry_job(wait: 10)
   end
  

  end
