[Here|https://app.circleci.com/pipelines/github/adelapena/cassandra/1968/workflows/1917904b-8a49-4bf6-9b39-282ac1af7424/jobs/19590]
is a new repeated CI run only for the new
{{{}CASTest.testConflictingWritesWithStaleRingInformation{}}}. The CircleCI
config file has been generated with:
{code:java}
.circleci/generate.sh -m \
-e REPEATED_UTEST_TARGET=test-jvm-dtest-some \
-e REPEATED_UTEST_COUNT=200 \
-e REPEATED_UTEST_CLASS=org.apache.cassandra.distributed.test.CASTest \
-e REPEATED_UTEST_METHODS=testConflictingWritesWithStaleRingInformation

The standard output, logs, and Junit report for each iteration can be found on
[the artifacts
tab|https://app.circleci.com/pipelines/github/adelapena/cassandra/1968/workflows/1917904b-8a49-4bf6-9b39-282ac1af7424/jobs/19590/artifacts].
The failed runs contain "fails" on the path, while the successful runs contain
"passes". For example, these are the files for the 2nd iteration of of the 6th
runner:
