Testing callbacks within batches?

Testing callbacks within batches?

[kmayer]

Here's how we do it at PacerPro:

We modified the worker so it returns a Sidekiq::Batch object:

class BatchSearch
  include Sidekiq::Worker

  def perform(search_id)
    @search = Search.find(search_id)

    Sidekiq::Batch.new.tap do |batch|
      batch.on(:complete, Callback, {'search_id' => search_id})
      batch.jobs do
        @search.end_points.each do |court|
          SearchWorker.perform_async(court.id, @search.id, jid)
        end
      end
    end
  end
end

and in RSpec, we call #perform to run synchronously, then batch.status.join to run the callbacks and check behavior.

      it 'changes the state of the search to "finished"' do
        expect {
          batch = worker.perform(search.id)
          batch.status.join
        }.to change { search.reload.status }.from("searching").to("finished")
      end

I'm also curious about this. Any suggestions?

This is an old discussion, I'm pretty sure that we came up with a satisfactory solution, since I'm not worried about it any more :-) I'll check my code. Ken

I mean, PRs are welcome, but I feel reasonably confident in speaking for the team that we're not going to to spend time working on it if it's a feature that perham thinks is unlikely to work well.

Sorry for the bump @kmayer. But I'm still interested ;)

If mike perham is against it we're probably not going to add it.
