As of Qverse CXF 1.5.7 we have only a very basic test there: https://github.com/quarkiverse/quarkus-cxf/tree/1.5.7/integration-tests/ws-rm
It is only setting up the WS-RM feature, but it is not checking whether the retransmission of lost messages works. That needs to be done in the next version - see CEQ-5349
