Doing sleep during a test isn't ideal. It would be better if the pid
of the test could be added as an option and if present the worker would notify the pid when the document was updated. Then the test would assert_received
for that message and timeout/fail if it doesn't happen.

I agree. The test doesn't really need to be notified when update_documents completes (it's mocked), but the :update_documents
should be in the worker's queue before the test continues.

as it stands, I think the PR's architecture implementation is wrong. The update_documents function should be blocking. I'd like to see failing test cases and work back from there to a solution

update_documents
is still blocking. It was already a handle_info
before this PR, I haven't changed that, and it schedules itself periodically, as before. I deferred it's invocation from init/1
to allow the worker (and it's supervision tree) to remain alive in the case of a temporary network error (domain resolution failure, for example).
Feel free to look at alternatives (#30).

I think instead this should be a separate functional call that is something like:
def init({provider_configs, pid}) is_id(pid) do
{:ok, state} = init(provider_configs)
Process.send(pid, :ready)
{:ok, state}
end
you can drop the handle_info
function

Third time lucky. I'm using Process.send_after
rather than Process.send
to ensure that update_documents will be in the workers inbox before the test proceeds.
@bcardarella sorry to bother but have you had a chance to give this any consideration? At the moment, without this PR or something similar, an |
sorry this has gone stale, DY doesn't have internal resources to support the library so I am going to start seeking an external maintainer. |
No problem... I'd be happy to help in a limited capacity. |
