Before this patch, all scripts which use test/cql-pytest/run.py looked for the Scylla executable as their first step. This is usually the right thing to do, except in two cases where Scylla is *not* needed: 1. The script test/cql-pytest/run-cassandra. 2. The script test/alternator/run with the "--aws" option. So in this patch we change run.py to only look for Scylla when actually needed (the find_scylla() function is called). In both cases mentioned above, find_scylla() will never get called and the script can work even if Scylla was never built. Signed-off-by: Nadav Har'El <nyh@scylladb.com> Closes #13010
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)
