optional arguments:
-h, --help show this help message and exit
--use-vnodes Determines wither or not to setup clusters using vnodes for tests (default: False)
--use-off-heap-memtables Enable Off Heap Memtables when creating test clusters for tests (default: False)
--num-tokens=NUM_TOKENS Number of tokens to set num_tokens yaml setting to when creating instances with vnodes enabled (default: 256)
--data-dir-count-per-instance=DATA_DIR_COUNT_PER_INSTANCE Control the number of data directories to create per instance (default: 3)
--force-resource-intensive-tests Forces the execution of tests marked as resource_intensive (default: False)
--skip-resource-intensive-tests Skip all tests marked as resource_intensive (default: False)
--cassandra-dir=CASSANDRA_DIR
--cassandra-version=CASSANDRA_VERSION
--delete-logs

--execute-upgrade-tests-only Execute Cassandra Upgrade Tests without running any other tests (e.g. tests annotated with the upgrade_test mark) (default: False)
--disable-active-log-watching Disable ccm active log watching, which will cause dtests to check for errors in the logs in a single operation instead of semi-realtime
processing by consuming ccm _log_error_handler callbacks (default: False)
--keep-test-dir Do not remove/cleanup the test ccm cluster directory and it's artifacts after the test completes (default: False)

--dtest-print-tests-only Print list of all tests found eligible for execution given the provided options. (default: False)
--dtest-print-tests-output=DTEST_PRINT_TESTS_OUTPUT Path to file where the output of --dtest-print-tests-only should be written to (default: False)
--pytest-options=PYTEST_OPTIONS Additional command line arguments to proxy directly thru when invoking pytest. (default: None)
--dtest-tests=DTEST_TESTS Comma separated list of test files, test classes, or test methods to execute. (default: None)
--configuration-yaml=CONFIG_FILE The name of the cassandra configuration YAML (e.g. cassandra_latest.yaml) (default: None)
