It is possible that a node will have no owned token ranges in some keyspaces based on their replication strategy, if the strategy is configured to have no replicas in this node's data center. In this case we should go ahead with cleanup that will effectively delete all data. Note that this is current very inefficient as we need to filter every partition and drop it as unowned. It can be optimized by either special casing this case or, better, use skip forward to the next owned range. This will skip to end-of-stream since there are no owned ranges. Fixes #13634 Also, add a respective rest_api unit test Closes #13849 * github.com:scylladb/scylladb: test: rest_api: test_storage_service: add test_storage_service_keyspace_cleanup_with_no_owned_ranges compaction_manager: perform_cleanup: handle empty owned ranges
Tests for the Scylla REST API.
Tests use the requests library and the pytest frameworks (both are available from Linux distributions, or with "pip install").
To run all tests using test.py, just run ./test.py api/run.
To run all tests against an already-running local installation of Scylla,
just run pytest. The "--host" and "--api-port"
can be used to give a different location for the running Scylla.
More conveniently, we have a script - "run" - which does all the work necessary to start Scylla, and run the tests on it. The Scylla process is run in a temporary directory which is automatically deleted when the test ends.
"run" automatically picks the most recently compiled version of Scylla in
build/*/scylla - but this choice of Scylla executable can be overridden with
the SCYLLA environment variable.
Additional options can be passed to "pytest" or to "run" to control which tests to run:
- To run all tests in a single file, do
pytest test_system.py. - To run a single specific test, do
pytest test_system.py::test_system_uptime_ms. - To run the same test or tests 100 times, add the
--count=100option. This is faster than runningrun100 times, because Scylla is only run once, and also counts for you how many of the runs failed. Forpytestto support the--countoption, you need to install a pytest extension:pip install pytest-repeat
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)
