Erratic India out in test (8)
I believe the answer is:
audition
'test' is the definition.
(I know that audition is a type of test)
'erratic india out' is the wordplay.
'erratic' indicates anagramming the letters.
'india'+'out'='indiaout'
'indiaout' is an anagram of 'AUDITION'.
'in' acts as a link.
(Other definitions for audition that I've seen before include "(To) assess (an actor)" , "Test of a performer's suitability" , "Hearing for actor seeking role in play" , "Trial performance for an artiste" , "Actor's trial performance" .)
