Has anyone used unit_tests_synthesizer.py??

It seems the function "adsp_filtering_test" is not completed.
There's no action defined for the condition " if any(val >0.0001 for val in diff): ", surely this would caused errors.
I didn't find clue for the "adsp" keyword, so I marked the function temporarily.
Is there anyone knowing what's the item for ? Or anyone can fix and complete this unit-tests script?
