assert_performed_jobs

Asserts that the number of performed jobs matches the given number. If no block is passed, perform_enqueued_jobs must be called around or after the job call.

def test_jobs
  assert_performed_jobs 0

  perform_enqueued_jobs do
    HelloJob.perform_later('xavier')
  end
  assert_performed_jobs 1

  HelloJob.perform_later('yves')

  perform_enqueued_jobs

  assert_performed_jobs 2
end

If a block is passed, asserts that the block will cause the specified number of jobs to be performed.

def test_jobs_again
  assert_performed_jobs 1 do
    HelloJob.perform_later('robin')
  end

  assert_performed_jobs 2 do
    HelloJob.perform_later('carlos')
    HelloJob.perform_later('sean')
  end
end

This method also supports filtering. If the :only option is specified, then only the listed job(s) will be performed.

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

Also if the :except option is specified, then the job(s) except specific class will be performed.

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

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

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

A proc may also be specified. When passed a Proc, the job’s instance will be passed as argument.

def test_hello_and_logging_jobs
  assert_nothing_raised do
    assert_performed_jobs(1, only: ->(job) { job.is_a?(HelloJob) }) do
      HelloJob.perform_later('jeremy')
      LoggingJob.perform_later('stewie')
      RescueJob.perform_later('david')
    end
  end
end

If the :queue option is specified, then only the job(s) enqueued to a specific queue will be performed.

def test_assert_performed_jobs_with_queue_option
  assert_performed_jobs 1, queue: :some_queue do
    HelloJob.set(queue: :some_queue).perform_later("jeremy")
    HelloJob.set(queue: :other_queue).perform_later("bogdan")
  end
end

      end
