Add verbose logging to identify failing test combinations in multi-DC setup: - Log replication factor (RF) and consistency level (CL) for each test iteration - Add validation checks for empty result sets Improve error handling: - Before indexing in a list, use `assert` to check for its emptiness - Use assertion failures instead of exceptions for clearer test diagnostics This change helps debug test failures by showing which RF/CL combinations cause inconsistent results between zero-token and regular nodes.

Scylla in-source tests.
For details on how to run the tests, see docs/dev/testing.md
Shared C++ utils, libraries are in lib/, for Python - pylib/
alternator - Python tests which connect to a single server and use the DynamoDB API unit, boost, raft - unit tests in C++ cqlpy - Python tests which connect to a single server and use CQL topology* - tests that set up clusters and add/remove nodes cql - approval tests that use CQL and pre-recorded output rest_api - tests for Scylla REST API Port 9000 scylla-gdb - tests for scylla-gdb.py helper script nodetool - tests for C++ implementation of nodetool
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.
