Stefania commented on CASSANDRA-9160:
-------------------------------------
The dtests are ready for review, I've already created a pull request:
https://github.com/riptano/cassandra-dtest/pull/321.
The problem with the cas unit tests failure was because of the CAS ballot time
uuid, which I had incorrectly set to request.now in
ModiciationStatement.casInternal(). I fixed it so that it should always be
bigger than the timestamp returned by QueryState..SP.beginAndRepairPaxos() does
something similar, but it doesn't look 100% correct to me. It might still fail
under heavy load, what do you think?
A tentative rearrangement, pending CI:
I had to move all {{CQLTester}} based tests into a separate folder,
_validation_, to distinguish the CQL tests from the following:
- tests based on {{SchemaLoader}}, occupying file names that we needed, such as
BatchTests or DeleteTest
- unit tests for Java classes (e.g. cql3/statements/SelectStatementTest in 2.1)
Inside this new folder I created these sub-folders:
- _operations_, for statements
- _entities_, for collections, secondary index, various types
- _util_, to host CQLTester
- _miscellaneous_, for everything else.
I am not too happy with the _validation_ folder so if you can think of
something else do tell, we could perhaps move them somewhere else entirely.

> We have CQL tests in 2 places: dtests and unit tests. The unit tests are
> actually somewhat better in the sense that they have the ability to test both
> prepared and unprepared statements at the flip of a switch. It's also better
> to have all those tests in the same place so we can improve the test
> framework in only one place (CASSANDRA-7959, CASSANDRA-9159, etc...). So we
> should move the CQL dtests to the unit tests (which will be a good occasion
> to organize them better).
