Re: [Libvirt-cim] [PATCH 1 of 3] [TEST] Add new enumerate infrastructure

# HG changeset patch # User Kaitlin Rupert <karupert(a)us.ibm.com&gt; # Date 1223330027 25200 # Node ID 66508277e8139993c9fb8bcc0368a77f8f597052 # Parent 311bf6eda3786eb8e47ede06c4da6dc1570aff61 [TEST] Add new enumerate infrastructure... CIM_CimtestClass, EnumNames, EnumInstances, and GetInstance will replace the existing CIM_MyClass, enumerate, enumerate_inst, and getInstance. Since there are a lot of tests to change, the original infrastructure is left in place. This should be removed once the tests are updated to use the new infrastructure. There's a few problems with the existing infrastructure. These replacesments aim to remove these issues: -A new classes require an entry in enumclass.py for each virt type. These changes remove the requirement. -A key_list is a necessary parameter to the enumerate calls. This goes against the extrinsic API definitions - the CIM API does not include an equivallent paremeter for the enumerate calls. -The enumerate() call currently takes a base classname, and a virt type. Really, the just the classname (complete with prefix) should be passed in. This way, SBLIM classes are supported in a more natrual
