Hi, My name is Roy and I'm one of the maintainers of SCT <https://github.com/scylladb/scylla-cluster-tests>, a framework to deploy and test Scylla & Cassandra clusters on various backends like (AWS, GCE, OpenStack and libvirt).
In general: - scdm.cluster: Contains cluster/node abstractions - scdm.nemesis: Cluster disruption procedures - scdm.remote: SSH library - scdm.tester: Contains base test class We regularly add more type of Nemesis (cluster disrupters) and tests. Important to note, It doesn't replace dtest but it's a useful framework to test the cluster as a whole for longer period of time with various scenarios. Feel free to use and contribute back. Roy - QA Manager, Scylla
