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 54425f02…ff477556 range are covered.

There were 18 non-merge commits from 6 authors in that period. Some notable commits:

There is no need to install python2 or python3 for cqlsh anymore as it supports relocatable python3, [so we stopped installing it.](https://github.com/scylladb/scylla-cluster-tests/commit/c67fdf46a7bfb55d72f42e2912f69918d33516a3)

[Added example jupyter notebooks](https://github.com/scylladb/scylla-cluster-tests/commit/76385e137c66861eadf127d02677bca61e2efcb0) that allow quick and easy way to interactively play with SCT cluster and try new code in SCT without a need to restart test.

Since we bumped JRE used by scylla-jmx from openjdk-8 to openjdk-11, [use openjdk-11 for testing offline installation](https://github.com/scylladb/scylla-cluster-tests/commit/26aa68d1c1aaaac799623742ee92c490aa4feb38).

[Added support to multi az in AWS](https://github.com/scylladb/scylla-cluster-tests/commit/798db4f8b3e68d7493e4ac76a5ee9c9f18773ad3) to enable coverage of test cases in multi-rack deployments. Adapted few of them to use multi az.

Adopted SCT to comply with the new procedure of ‘Handling Cluster Membership Change Failures’. Now we [compare members of token ring with group0](https://github.com/scylladb/scylla-cluster-tests/commit/879fc686c55a77c3e4a89c5b61d985c956e9c5d0) and remove garbage member with removenode operation. We also started to [check group0 token ring consistency](https://github.com/scylladb/scylla-cluster-tests/commit/582ad59c6531395e8dadf670f0d78c5c3a6c87e4) after each nemesis.

[Add-remove MV nemesis](https://github.com/scylladb/scylla-cluster-tests/commit/e37d416e259c2ae1a3c9bd7fa389f11e42cd60eb) was added to cover the case of adding and removing materialized view when one node is down.

[Run “kill\_test” method only once](https://github.com/scylladb/scylla-cluster-tests/commit/ff477556b85d35096ab56c744b880dc96c0d82ca), so we avoid endless failure loop - hopefully fixing important issue of not stopping the test properly.

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