[jira] [Commented] (CASSANDRA-16180) 4.0 Quality: Coordination Test Audit

["Caleb Rackliffe (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-16180?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17229571#comment-17229571 ] 

Caleb Rackliffe commented on CASSANDRA-16180:
---------------------------------------------

[~adelapena] I'm still reading through the doc, but once place we might be able to improve our coverage is {{UpgradeTest}}. It basically looks like a coordination test through upgrade w/ mixed version clusters, but it isn't as exhaustive as what you did for {{MixedModeReadRepairTest}} in terms of the version transitions. It also only queries at {{ALL}}, so we might be able to stop nodes and move down the consistency level chain in {{runAfterClusterUpgrade()}} as well as executing the mixed cluster queries in {{runAfterNodeUpgrade()}}.

> This is a subtask of CASSANDRA-15579 focusing on coordination.
> I think that the main reference dtest for this is [consistency_test.py|https://github.com/apache/cassandra-dtest/blob/master/consistency_test.py]. We should identify which other tests cover this and identify what should be extended, similarly to what has been done with CASSANDRA-15977.
> [This document|https://docs.google.com/document/d/1BBeGKla9tIPflZ2awkyfl5Hc_FTs3QYw98LWUnb1fTQ/edit?usp=sharing] aims to list and describe the existing functional tests for coordination, so we can have a broad view of what is currently covered.
