Current upgrade dtest rely on a ccm node function to get_highest_supported_sstable_version() that looks for r'Feature (.*)_SSTABLE_FORMAT is enabled' in the log files. Starting from scylla-6.0 ME_SSTABLE_FORMAT is enabled by default and there is no cluster feature for it. Thus get_highest_supported_sstable_version() returns an empty list resulting in the upgrade tests failures. This change introduces a seperate API path that returns the highest supported sstable format (one of la, mc, md, me) by a scylla node. Fixes scylladb/scylladb#19772 Backports to 6.0 and 6.1 required. The current upgrade test in dtest checks scylla upgrades up to version 5.4 only. This patch is a prerequisite to backport the upgrade tests fix in dtest. Closes scylladb/scylladb#19787
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)
