From c1497cf44f466d3093c8ab29e7c0c48ad3c2f9e4 Mon Sep 17 00:00:00 2001 From: Chris Evich Date: Thu, 14 Oct 2021 14:32:20 -0400 Subject: Test-hang fix: Wait for ready + timeout on connect. It was observed during initial F35 testing, this test can cause Ginkgo to "hang" by attempting to connect before the redis is up/listening. Fix this by confirming the ready-state before attempting to connect. Also, force IPv4 and timeout on any connection fault - to allow other tests to run. Thanks to Adrian Reber for help on this and related fixes.
