Pls suggest me a good config for test environment to create exchange full futures, with Lync server integration as well...

A good start for the Exchange part is two CAS+HT servers, two Mailbox servers, and an Edge Transport server. To test a disaster recovery site, you can add one CAS+HT server and a mailbox server in a separate AD site. Of course you need at least one domain controller in each site. For testing, you can easily implement all of this on one Hyper-V or VMware ESX server that has sufficient resources. You're welcome to ask what you should have for Lync in the Lync forum.
