Went by and didn’t fail (6)
I believe the answer is:
passed
I believe this clue is a double definition.
'went by' is the first definition.
('pass' can be a synonym of 'go by')
'didn't fail' is the second definition.
(I've seen this in another clue)
'and' acts as a link.
(Other definitions for passed that I've seen before include "Handed on; went by" , "'Brought into effect, laws perhaps (6)'" , "Spades (anag)" , "Gone" , "Failed to bid" .)
