DCAE test-suites under integration/gating are currently using cloudify blueprint to deploy MS on-demand (via deployment-handler/dashboard api).
WIth on-going DCAE transformation to migrate all components deployment via helm, need test-suite to switch using helm charts available part of OOM repo (under https://git.onap.org/oom/tree/kubernetes/dcaegen2-services/components)
Either wrapper scripts (which will inturn invoke helm) or API's provided by Mutlicloud/K8S plugin could be an option to deploy charts into ONAP cluster.
The scope of this story for Istanbul is come up with prototype to migrate anyone testsuite.
<solution to be further explored with Integration/OOM team>
