New test run charge (7)
I believe the answer is:
entrust
'charge' is the definition.
(as in entrusting or charging someone with a task)
'new test run' is the wordplay.
'new' is an anagram indicator.
'test'+'run'='testrun'
'testrun' with letters rearranged gives 'ENTRUST'.
(Other definitions for entrust that I've seen before include "Commit (for safety)" , "Consign" , "Assign (a responsibility to someone)" , "Commend" , "Confide" .)
