Recently, when running Alternator tests we get hundreds of warnings like
the following from basically all test files:
/usr/lib/python3.12/site-packages/botocore/crt/auth.py:59:
DeprecationWarning: datetime.datetime.utcnow() is deprecated and
scheduled for removal in a future version. Use timezone-aware objects
to represent datetimes in UTC: datetime.datetime.now(datetime.UTC).
/usr/local/lib/python3.12/site-packages/pytest_elk_reporter.py:299:
DeprecationWarning: datetime.datetime.utcnow() is deprecated and
scheduled for removal in a future version. Use timezone-aware objects
to represent datetimes in UTC: datetime.datetime.now(datetime.UTC).
These warnings all come from two libraries that we use in the tests -
botocore is used by Alternator tests, and elk reporter is a plugin that
we don't actually use, but it is installed by dtest and we often see
it in our runs as well. These warnings have zero interest to us - not
only do we not care if botocore uses some deprecated Python APIs and
will need to be updated in the future, all these warnings are hiding
*real* warnings about deprecated things we actually use in our own
test code.
The patch modifies test/pytest.ini (used by all our Python tests,
including but not limited to Alternator tests) to ignore deprecation
warnings from *inside* these two libraries, botocore and elk_reporter.
After this patch, test/alternator/run finishes without any warnings
at all. test/cqlpy does still have a few warnings left, which earlier
were hidden by the thousands of spammy warning eliminated in this patch.
We fix one of these warnings in this patch:
ResultSet indexing support will be removed in 4.0.
Consider using ResultSet.one()
by doing exactly what the warning recommended.
Some deprecation warnings in test/cqlpy remain in calls to
get_query_trace(). The "blame" for these warning is misplaced - this
function is part of the cassandra driver, but Python seems to think it's
part of our test code so I can't avoid them with the pytest.ini trick,
I'm not sure why. So I don't know yet how to eliminate these last warnings.

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
