This short report brings to light some interesting commits to [scylla-cluster-tests.git master](https://github.com/scylladb/scylla-cluster-tests) from the last week. Commits in the b0808417…94f0945a range are covered.

There were 77 non-merge commits from 12 authors in that period. Some notable commits:

Multi-value config options are now [strictly typed lists](https://github.com/scylladb/scylla-cluster-tests/commit/22455448e1bddd5712044197d769adb546ead688), and [string options follow the same rule](https://github.com/scylladb/scylla-cluster-tests/commit/72edfc92358e1209ee71d8d94a1466e66ead9b5f). Test cases [moved to the list form](https://github.com/scylladb/scylla-cluster-tests/commit/c0229031b57d01049f3c3abf3b0340d5251c8471), so `n_db_nodes: '3 3'` becomes `n_db_nodes: [3, 3]` and `nemesis_seed: '256'` becomes `256`.

Vector-store can now [log in to ScyllaDB under its own role and service level](https://github.com/scylladb/scylla-cluster-tests/commit/82af2abe8108f40e17f5136d7a202e0b6cc2588d) for SLA and QoS testing. Set `vector_store_scylla_username`, which requires `PasswordAuthenticator`, or use the `configurations/vector_store_service_level.yaml` overlay.

The event system [classifies Scylla log lines by the level Scylla reported](https://github.com/scylladb/scylla-cluster-tests/commit/d59222a103b301eb62c9be8104169debec430c47), so an INFO-level line never raises an ERROR event and `ignore_ignore_runtime_errors` is gone. An event type can also [supply a finer-grained Argus aggregation id](https://github.com/scylladb/scylla-cluster-tests/commit/dd6426eb1372aae7361542540e51df1e7f1056a6).

Every test now [stops the scylla perf-collector at teardown and collects its recordings](https://github.com/scylladb/scylla-cluster-tests/commit/84a8be36132a4b2a25b26ce92624e9cccd7bbdc2) from `/var/log/scylla-perf`. Nodes that outlive the test get the collector started again.

Latte was [bumped to 0.54.0](https://github.com/scylladb/scylla-cluster-tests/commit/48f87649a0975fda629ff9f65d62563340d949e6). The release moves the Alternator workload onto the published Alternator client 1.0 and prints the parameters of a query that fails.

Scylla Doctor was [bumped to 1.14.2](https://github.com/scylladb/scylla-cluster-tests/commit/b08084178b4cf3bdbdefa9d772fb19794712146a). The release treats network-backed NVMe as non-NVMe storage, flags a keyspace DC with replication factor 0, and masks `DESC SCHEMA` in the cluster diff.

The minicloud emulator [reached v0.7.0](https://github.com/scylladb/scylla-cluster-tests/commit/0e17e7cdd76aa7d1c66007fd55fe94ffbc067404), which resolves S3 names in the guests and serves buckets from a local store. SCT [passes `scylla-qa-team` through to real S3](https://github.com/scylladb/scylla-cluster-tests/commit/4e5aba3cdc76186cd90f0806c853b599c3711666) for the nemeses that load sstables.

See you in the next issue of last week in scylla-cluster-tests.git master!
