I’m testing a function that also sends a cast to a GenServer as such;
The event is an Ecto struct, stored in a database. The dispatch function enqueues the event and dispatches it asynchronously. After the event has been sent, it’ll be updated in the database with the status result of the webhook.
The issue is the test finishes before the event is dispatched. So as the GenServer is doing its work it will render an Ecto.StaleEntryError. I think that is due to the database isolation for each test or process.
In this test I’m not interested in whether or not the dispatch is successful, I just want the cast to happen and that’s it.
I’ve managed to “solve” the problem by mocking the GenServer and just returning an
:ok instead of actually enqueueing anything. Another “solution” was to have the test sleep for 100ms so the process wasn’t killed, but well, you know, sleeping in tests…
Is this the right way to solve this issue or are there better ways to do so?
