This is a translation of Cassandra's CQL unit test source file
OperationFctsTest.java into our cql-pytest framework.
This is a massive test suite (over 800 lines of code) for Cassandra's
"arithmetic operators" CQL feature (CASSANDRA-11935), which was added
to Cassandra almost 8 years ago (and reached Cassandra 4.0), but we
never implemented it in Scylla.
All of the tests in suite fail in ScyllaDB due to our lack of this
feature:
Refs #2693: Support arithmetic operators
One test also discovered a new issue:
Refs #20501: timestamp column doesn't allow "UTC" in string format
All the tests pass on Cassandra.
Some of the tests insist on specific error message strings and specific
precision for decimal arithmetic operations - where we may not necessarily
want to be 100% compatible with Cassandra in our eventual implementation.
But at least the test will allow us to make deliberate - and not accidental -
deviations from compatibility with Cassandra.
