Yeah, I admit it is redundant from some perspective. I think the lit tests are different with the unittest. The lit tests check if the end behavior is expected. And the unittest tests checks if the status of the attribute is expected. For example, it is possible to discard the changes in this patch and keep these lit tests passes.

I think more tests are always good. Especially now it is not hard to add these tests.
