<# .Description
Pester tests for DRSRule PowerShell module. Expects that: 0) DRSRule module is already loaded (but, will try to load it if not) 1) a connection to at least one vCenter is in place (but, will prompt for XMS to which to connect if not) 2) there are one or more existing DRS items of each type to test (VMGroup, VMHostGroup, etc.) in the specified cluster .Example Invoke-Pester -Script @{Path = '\\some\path\DRSRule\testing\DRSRule.Tests_Get.ps1'; Parameters = @{Cluster = "myFavoriteCluster"}} Invokes the tests in said Tests script, passing the given Cluster parameter value, to be used for the cluster-specific tests #> param ( ##
