CMDB for testing environment assets/ci's

Hello. I've been reading some Eli Eyal's blog articles about CMDB / UCMDB and my question is ¿how is the recomendation to manage hundreds of testing ci's in a CMDB with a lot of bizservice assets, applications assets, hardware equipment, all of them identified as production environment but how to connect them with all the testing, development servers/test application behind them?  I would like to know how is that manage in other companies as a success case.

Thanks in advance.
