You testers tired of continually setting up your test only to find have bug that can't be reproduced?
S. Soma Somasegar, Corporate VP of Developer Division describes the features in Visual Studio Team System 2010 for Lab Management in his blog posting, Lab Management in VSTS 2010.
He describes a world where virtualization combined with integration with Application Lifecycle Management and System Center Virtual Machine Manager gives new meaning to "Lab Management". It is built specifically to accelerate setup/tear down/restore of complex virtual environments to a clean state. The no-repro problem is solved by allowing testers to file rich bugs with links to environment checkpoints so developers can recreate bugs in complex environments.
Developers launch a virtual environment with one click of a button that exactly matches the one where bug was found. Build automation handles virtual machine provisioning, build deployment and build verification.
