To keep our cql-pytest tests "correct", we should strive for them to pass on Cassandra - unless they are testing a Scylla-only feature or a deliberate difference between Scylla and Cassandra - in which case they should be marked "scylla-only" and cause such tests to be skipped when running on Cassandra. The following few small patches fix a few cases where our tests we failing on Cassandra. In one case this even found a bug in the test (a trivial Python mistake, but still). Closes #8694 * github.com:scylladb/scylla: test/cql-pytest: fix python mistake in an xfailing test test/cql-pytest: mark some tests with scylla-only test/cql-pytest: clean up test_create_large_static_cells_and_rows
Single-node funtional tests for Scylla's CQL features. Tests use the Python CQL library and the pytest frameworks. By using an actual CQL library for the tests, they can be run against any implementation of CQL - both Scylla and Cassandra. Most tests - except in rare cases - should pass on both, to ensure that Scylla is compatible with Cassandra in most features.
To run all tests against an already-running local installation of Scylla
or Cassandra on localhost, just run pytest. The "--host" and "--port"
can be used to give a different location for the running Scylla or Cassanra.
More conveniently, we have two scripts - "run" and "run-cassandra" - which do all the work necessary to start Scylla or Cassandra (respectively), and run the tests on them. The Scylla or Cassandra process is run in a temporary directory which is automatically deleted when the test ends.
Additional options can be passed to "pytest" or to "run" / "run-cassandra" to control which tests to run:
- To run all tests in a single file, do
pytest test_table.py. - To run a single specific test, do
pytest test_table.py::test_create_table_unsupported_names.
Additional useful pytest options, especially useful for debugging tests:
- -v: show the names of each individual test running instead of just dots.
- -s: show the full output of running tests (by default, pytest captures the test's output and only displays it if a test fails)
