The test cases are different - one is changing the information returned for a single write operation, while the other is changing the return when a write service call include multiple items to be written (not all client will even issue a write with multiple items).

the keyword on the test cases for all of the Attribute write should be updated to indicate just simple write or array as needed - this might be adding to confusion of what a test is actually testing. - the description of the test cases and the keyword should be updated
