Hate being tested, maybe (6)
I believe the answer is:
detest
'hate' is the definition.
(to detest is to hate or loathe)
'tested maybe' is the wordplay.
'maybe' indicates anagramming the letters.
'tested' is an anagram of 'DETEST'.
'being' acts as a link.
(Other definitions for detest that I've seen before include "Cordially dislike and loathe" , "Be unable to stand" , "Loathe, hate intensely" , "Really dislike" , "Dislike intensely, loathe" .)
