If you look at the last paragraph, it seems aphyr has been involved in the development:

> I was not alone during the past months, while hacking with Disque and trying to figure out how to shape it, I received the help of: [...] Kyle Kingsbury, [...] Redis Labs and Pivotal, and probably more people I’m not remembering right now. Thank you for your help.

Good hint. I tried to run the initial tests Kyle (Aphyr) wrote for Disque in order to debug a problem, and after running Jepsen a few times you realize how cool it is, and you want to run your own tests. However Jepsen is a non trivial system and requires some Clojure skill, so I postponed this activity for later... resorting to simpler systems to test Disque for now. But soon or later I want to spend a few weeks at learning Jepsen and enough Clojure in order to do my tests.

However note that the value of having Kyle testing Disque is not just his ability to use Jepsen well (of course) but also the design of the tests so in order to stress the right things to find bugs. And finally the whole analysis that is performed together with the test. So regardless of the fact I'll learn Jepsen or not I hope Disque will get some official testing with Jepsen. However I understand Kyle is a single person and there is a huge queue of systems to be tested.
