Andres de la Peña commented on CASSANDRA-16180:
-----------------------------------------------
[~maedhroz] I'm adding [a
document|https://docs.google.com/document/d/1BBeGKla9tIPflZ2awkyfl5Hc_FTs3QYw98LWUnb1fTQ/edit?usp=sharing]
describing the existing dtests for coordination. I think that they are in
quite better shape than the ones we found for read repair during
CASSANDRA-15977, which is unsurprising given how fundamental coordination is.
After giving it a thought I think that splitting {{StorageProxy}} and trying to
add some unit tests to the separated components is a good thing to do here,
particularly for the range read logic, as you said.
I also agree that it's better to leave Paxos/CAS out of the scope of this
ticket.

> 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.
