22"""Unit test for `ApdbCassandra` class.
24Notes
25-----
26For now this test can only run against actual Cassandra cluster, to specify
27cluster location use ``DAX_APDB_TEST_CASSANDRA_CLUSTER`` environment variable,
28e.g.:
30 export DAX_APDB_TEST_CASSANDRA_CLUSTER=cassandra.example.com
31 pytest tests/test_apdbCassandra.py
33Individual tests create and destroy unique keyspaces in the cluster, there is
34no need to pre-create a keyspace with predefined name.
