    23 @SYMTestCaseDesc          Tests the performance of a bulk delete operation on a corporate-profile 
       
    24 						  database of 1000 contacts.
       
    25 						  
       
    26 @SYMTestActions           Measures the time taken to perform a bulk delete on the contacts database
       
    27 						  by passing a CContactIdArray to:
       
    28 						  -- CContactDatabase::DeleteContactsL()
       
    29 
       
    30 @SYMTestExpectedResults   Test case will run without leaving and will output timing information.
