@RajaKullaiahD3386 Deployment Manager uses same API which prpcServiceUtils uses for imports/exports, etc. If customer want to use CI/CD tools like bamboo they can use API uses in prpcServiceUtils.
I hope you are already using Pega Deployment Manager, if executing standard selenium test suite is concerned then using Jenkins integration these test cases can be executed. Please refer to below link.
@RajaKullaiahD3386 Deployment manager don't support directly running Maven commands, rather Jenkin integration is supported by deployment manager. So that you can still use Jenkins to run standard selenium suite from deployment manager pipeline.
