Tests are short-lived and use a small amount of data. They are also often run repeatly, and the data is deleted immediately after the test. This is a good scenario for using the kernel page cache, as it can cache read-only data from test to test, and avoid spilling write data to disk if it is deleted quickly. Acknowledge this by using the new --kernel-page-cache option for tests. This is expected to help on large machines, where the disk can be overloaded. Smaller machines with NVMe disks probably will not see a difference. Closes #8347
Tests for Scylla with Redis API that should also pass, identically, against Redis.
Tests use the redis library for Redis API, and the pytest frameworks (both are available from Linux distributions, or with "pip install").
To run all tests against the local installation of Scylla with Redis API on
localhost:6379, just run pytest.
Some additional pytest options:
- To run all tests in a single file, do
pytest test_strings.py. - To run a single specific test, do
pytest test_strings.py::set. - 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)
