any thoughts on how to support delay class methods?

I've not had need to use the delayed extensions kit in Sidekiq so haven't given this any thought up to now.

FYI from looking at some of the Sidekiq code there are comments that using the delayed methods are discouraged anyway due to serialization of the entire object to JSON.

However, if I read Sidekiq's source correctly, this should be testable with the current matchers (don't hold me to that).

Scanning over the extensions directory in Sidekiq's source, everything hangs round the Proxy class and it's method_missing method. The end game appears to be the job enqueued via the usual #client_push method but with some additional arguments added (most importantly the name of the method being called). I've not looked any further but there must be logic in Sidekiq that looks at arguments and calls the relevant method when the job is invoked.

So you should be able check a job in enqueued correctly and the expected arguments (You'll have to take a peek to see what those arguments are). As for the method being called, I'd test that the job is enqueued as expected (as above) and then test the method itself separately (else your testing that Sidekiq is actually performing it's job correctly which is already tested in Sidekiq itself).

It's discouraged to use active_record extension. Using class methods actually will not have any serialization problem as long as the arguments are plain.

I'm actually interested in testing if arguments are correctly passed in, using have_enqueued_job. Currently I can only test if the size of the DelayClass has changed using Sidekiq::Extensions::DelayedClass.jobs.

Using have_enqueud_job on Sidekiq::Extensions::DelayedClass gives me:

[["---\n- !ruby/class 'EmailListManager'\n- :add_user_to_list\n- - 1\n - free\n"]]

when I called EmailListManager.delay.add_user_to_lis(1, 'free')

I'll look into how this argument get parsed.

Did you get any further with this?

Hi Phil,

I realized that It's not very readable to test Sidekiq::Extensions::DelayedClass. So I wrote a simple dsl to generate sidekiq job class instead.

I've got some helper methods for testing the delay class methods. Will create a pull request.
