Hey all! Im wondering if anyone have a good example or could help me understand how should I test an async task. The closer I found was this question Testing Task Async , but it’s not that clear (at least for me). So basically I have a module defmodule Personas def onboard(email) do Task.st…

Thanks @stefanchrobot ! But Im looking for a way to test my current implementation. I would like to not introduce a supervisor (and all the code around it) just because there is no other way to test it. Tbh If that’s the only way of doing it, I would just leave the sleep instruction :confused:

If you want to wait for the task, you’ll need to either start it with something that returns a Task.t you can await, or include a way for the code to signal completion. For instance: defmodule Personas def onboard(email, cb \\ fn -> :ok end) do Task.start_link(fn -> process_onboard(email); cb…

Hi @mustela ! I agree with @LostKobrakai ’s response from the topic you linked: Testing Task Async - #2 by LostKobrakai . I would refactor the code to unit test only the abstractions that I have control over and by definition can properly be observed. I’d say that if both functions inside onboard/1 d…

Hey everyone! First of all, I have to thank you all for your awesome feedback. The fact that even @josevalim is answering to this “simple” question, expose how humble and awesome this community is… :bowing_man: About my particular problem, I took more time reading about supervisors and processes (I…
