ActiveJob's assert_enqueued_with at comparison

gistfile1.txt

I use this method instead of ActiveJob's original version to assert for enqueued job with given parameters / options.

The main point of this patch is to fix the float to float comparison with the at attribute by using an epsilon which can also be provided.

With the original version, it is impossible to test if a job is enqueued at a specified time.

I also added the wait attribute, which correspond more to my use of ActiveJob.

gistfile2.rb

def assert_enqueued_with(args = {}, &block)
  original_enqueued_jobs = enqueued_jobs.dup
  clear_enqueued_jobs
  args[:at] = args.delete(:wait).seconds.from_now.to_f if args.has_key?(:wait)
  at = args.delete(:at)
  epislon = args.delete(:epislon) || 0.1
  args.assert_valid_keys(:job, :args, :queue)
  yield
  matching_job = enqueued_jobs.any? do |job|
    matching = args.all? { |key, value| value == job[key] }
    if at
      matching &= job.has_key?(:at) && (job[:at] - at).abs < epislon
    end
    matching
  end
  assert matching_job, "No enqueued job found with #{args}"
ensure
  queue_adapter.enqueued_jobs = original_enqueued_jobs + enqueued_jobs
end
