Country ended test (8)
I believe the answer is:
pastoral
'country' is the definition.
(thesaurus)
'ended test' is the wordplay.
'ended' becomes 'past' (I've seen this before).
'test' becomes 'oral' (oral is a type of examination).
'past'+'oral'='PASTORAL'
(Other definitions for pastoral that I've seen before include "Country's" , "bishop's staff" , "Bucolic, rural" , "Type of poem" , "Of sheperds, or concerned with spiritual guidance" .)
