Integration/Acceptance Testing for PoshCore-CoreQuery.ps1
Invoke-Pester –Script @{'Path' = 'C:\Githubdata\poshcore\Tests\PoshCore-CoreQuery.Tests.ps1';}
Description: Run through the three variations of data than needs to be exspanded using function Convertfrom-Subattributes which is in PoshCore-CoreQuery.ps1
Note: Help for sku expantion in Convertfrom-Subattributes covers details of how it works and the data it should retrun.

Ticket must have subtickets and computers attached.
Note:
When a methord for adding subtickets is created, we can have this test created an new ticket and assign a subticket.
When a methord for closing a ticket is created we can have this test close the ticket ticket after creation.
