Port some tests

[Earlopain]

A bit for #21

There was one typo I noticed in an unrelated test where workers_per_queue => queues_per_worker. It doesn't impact the test since queues - 1 is the default value

Aha, thanks for taking these on! Feel free to update that issue as you see fit 🙏

Good catch, we probably ought to validate these and raise an error or warning.

That sounds reasonable, yes. I also noticed that when I accidentally set the queues higher than the total number of workers a portion of requests just hang. queues <= number_of_workers validation may also make sense.
