The original make_memtable used seastar::thread::yield() for preemption, which required all callers to run inside a seastar::thread context. This prevented the utilities from being used directly in coroutines or parallel_for_each lambdas. Make the primary functions — make_memtable, make_sstable_containing, and verify_mutation — return future<> directly. Callers now .get() explicitly when in seastar::thread context, or co_await when in a coroutine. make_memtable now uses coroutine::maybe_yield() instead of seastar::thread::yield(). verify_mutation is converted to coroutines as well.

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.
