SQL Server cluster failover If I have a cluster and I pause the SQL Server Service on the active server with the cluster interpret this as a failure and attempt to fail-over?

I tried this on a failover cluster test on my laptop (Windows 2008 Enterprise eval running SQL Server 2008 R2 SP1), open SQL server configuration manager and stop SQL server service on the (active) node wait for couple of minutes but somehow SQL server db service did not failed over?
Failover clustering works to provide constant service in the event of a failure (defining a failure as an "abnormal termination of the previously active application, server, system, or network" - http://en.wikipedia.org/wiki/Failover).  Manual manipulation (start, restart, pause, and stop) upon the service being clustered (SQL Server, File Services, etc.) does not qualify as an abnormal termination of the service.

If I recall, at least in Windows Server 2008, you can simulate a failover test case in the Failover Management Console under Administration Tools.  Check this out for a list of testing methods: http://blogs.technet.com/b/vipulshah/archive/2009/06/17/failover-cluster-testing-methods.aspx
