/*
    This test client executes a set of tests against a known provider for
    the class Test_CIM_ErrorResponse defined specifically to return
    CIM_Error objects.  It executes getInstance and enumerateInstance
    tests and determines if the responses are the expected CIM_Error
    instances.

    NOTE: Today this test does not cause failure if the expected count of
    CIM_Errors is not received because there are issues with handling
    CIM_Error internally in Pegasus.  There are two known return paths
    that do work (XML and binary response with chunking disabled and
    OOP disabled)  Oct 2011. See bug 5917 or links from that bug
    for further information
