Hate being tested, perhaps (6)
I believe the answer is:
detest
'hate' is the definition.
(to detest is to hate or loathe)
'tested perhaps' is the wordplay.
'perhaps' is an anagram indicator.
'tested' with letters rearranged gives 'DETEST'.
'being' acts as a link.
(Other definitions for detest that I've seen before include "Cordially laothe" , "Greatly hate" , "Dislike thoroughly" , "Dislike intensely, think badly of" , "Find repulsive" .)
