Same issue

DBConnection.ConnectionError when testing channels with Phoenix Presence

I’ve been building the follow-along Rumbl app while reading the Programming Phoenix book and ran into some issues testing my channels. When running the tests I get the following output: 07:31:35.021 [error] Postgrex.Protocol (#PID<0.331.0>) disconnected: ** (DBConnection.ConnectionError) owner #PID<0.665.0> exited Client #PID<0.668.0> is still using a connection from owner at location: :prim_inet.send_recv_reply/2 (postgrex 0.15.7) lib/postgrex/protocol.ex:2918: Postgrex.Protocol.do_s…

Can’t express how frustrating it is for the book to literally end on such a cryptic-for-beginners bug.

Does this mean we just can’t test channels?
