One of the design goals of the Alternator test suite (test/alternator)
is that developers should be able to run the tests against some already
running installation by running `cd test/alternator; pytest [--url ...]`.
Some of our presentations and documents recommend running Alternator
via docker as:
docker run --name scylla -d -p 8000:8000 scylladb/scylla:latest
--alternator-port=8000 --alternator-write-isolation=always
This only makes port 8000 available to the host - the CQL port is
blocked. We had a bug in conftest.py's get_valid_alternator_role()
which caused it to fail (and fail every single test) when CQL is
not available. What we really want is that when CQL is not available
and we can't figure out a correct secret key to connect to Alternator,
we just try a connect with a fake key - and hope that the option
alternator-enforce-authorization is turned off. In fact, this is what
the code comments claim was already happening - but we failed to
handle the case that CQL is not available at all.
After this patch, one can run Alternator with the above docker
command, and then run tests against it.
By the way, this provides another way for running any old release of
Scylla and running Alternator tests against it. We already supported
a similar feature via test/alternator/run's "--release" option, but
its implementation doesn't use docker.
Fixes #22591

Closes scylladb/scylladb#22592
Scylla in-source tests.
For details on how to run the tests, see docs/dev/testing.md
Shared C++ utils, libraries are in lib/, for Python - pylib/
alternator - Python tests which connect to a single server and use the DynamoDB API unit, boost, raft - unit tests in C++ cqlpy - Python tests which connect to a single server and use CQL topology* - tests that set up clusters and add/remove nodes cql - approval tests that use CQL and pre-recorded output rest_api - tests for Scylla REST API Port 9000 scylla-gdb - tests for scylla-gdb.py helper script nodetool - tests for C++ implementation of nodetool
If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
