+ Review comment: For this test as well as the `givenHashValueDeleted` test below, we aren't actually testing that the bytes decreased as the test name suggests. We are testing that they return to their initial values. The above test (`should_showDecreaseInDatastoreBytesInUse_givenStringValueDeleted`) does test that the bytes decrease.... we could potentially do both things (get the bytes before any operation, get the bytes after an operation, and get the bytes after a del, then verify the bytes decreased and then returned to their initial value)... -- This is an automated message from the Apache Git Service.
