The tc will fail in the following conditions:

1) if p == "DiskPool" and libvirt_version < '0.4.1' and when there is no 
diskpool on the machines.
2) Also, when the NetworkPool does not exist OR when the existing 
NetworkPool are in inactive states.
We can improve the test case by making sure we have atleast one of each 
type of the pool and then verify that the AC and the various pools 
return the similar results.
Also, Can we include the comment that you have in the patch in the test 
case as it does not have any comments as of now and also, it will 
provide as a reference for maintenance of the tc.
