ECONNREFUSED when starting coordination tests #97

Open evabishchevich opened 7 years ago

evabishchevich commented 7 years ago

We have strange behaviour on CI when coordination test can't start because of ECONNREFUSED error. Looks like all devises are on the same wifi.

Logs: https://github.com/ThaliTester/TestResults/tree/9953060646c88db_Add_listening_to_connectivity_events_when_app_starts_evabishchevich/ thali02 and thali04 devices

It seems that clients sometimes try to connect to coordination server before the server is started. Look at the timestamps from the logs above.

Coordination server start:

2016-12-28 10:52:58 - INFO HttpServer: 'listening on *:3000'

Device that didn't connect from node thali02 (it tries to connect 20 seconds before server is started):

The fix is incorrect. The server waits for signal from node to start itself so the timeout for delaying node code execution is not helping. We need to prepare other solution.

Please verify server-address.js and ssid of wifi network for client.
