rails--rails/activejob/CHANGELOG.md

• A generated job now inherents from app/jobs/application_job.rb by default.

  Jeroen van Baarsen

• Add an :only option to perform_enqueued_jobs to filter jobs based on type.

  This allows specific jobs to be tested, while preventing others from being performed unnecessarily.

  Example:

  def test_hello_job
    assert_performed_jobs 1, only: HelloJob do
      HelloJob.perform_later('jeremy')
      LoggingJob.perform_later
    end
  end
  

  An array may also be specified, to support testing multiple jobs.

  Example:

  def test_hello_and_logging_jobs
    assert_nothing_raised do
      assert_performed_jobs 2, only: [HelloJob, LoggingJob] do
        HelloJob.perform_later('jeremy')
        LoggingJob.perform_later('stewie')
        RescueJob.perform_later('david')
      end
    end
  end
  

  Fixes #18802.

• Allow keyword arguments to be used with Active Job.

  Fixes #18741.

  Sean Griffin

• Add :only option to assert_enqueued_jobs, to check the number of times a specific kind of job is enqueued.

  Example:

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

  George Claghorn

• 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
