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 the job call.

def test_jobs
  assert_performed_jobs 0

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

  perform_enqueued_jobs do
    HelloJob.perform_later('yves')
    assert_performed_jobs 2
  end
end

If a block is passed, that block should 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

The block form 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
