Use Websockex to replace websocket_client
Test that server will disconnect websocket upon token revocation
Lint
Execute session disconnect in background
Refactor streamer test
allow multi-streams
rebase websocket change
In general, tests that match these criteria can be made async:
- Doesn't use real Cachex.
- Doesn't write to the Config / Application Environment.
- Uses Mock. Using Mox is fine.
- Uses the streamer.
