@njr-11 I forget to update this one:

#828

It looks like one of the skips (covering key-value without eventual consistency) was lost, so I added a suggestion to put it back.

Also, I see this line later in the test which is another occurrence that will need to be covered:

        assertEquals(2, shared.deleteIfPositive());

Also, I think we need to add a method to the MultipleEntityRepo returning void,

    @Query("DELETE FROM Coordinate WHERE x > 0.0d AND y > 0.0f")
    void deleteIfPositive_EventualConsistency();

which can be used within the catch where it says:
// Use alternative approach for ensuring no data is present:

because it doesn't currently do anything, and then subsequent assertions check that the data was deleted.

@njr-11 done

Looks good, but we also need to add the line to use the new method in the two places where it says "Use alternative approach..."
