Again explore a strange street (6)

I believe the answer is:

retest

I'm a little stuck... Click here to teach me more about this clue!

'again explore a' is the definition.
I can't judge whether this defines the answer.

'strange street' is the wordplay.
'strange' is an anagram indicator.
'street' anagrammed gives 'RETEST'.

Can you help me to learn more?

(Other definitions for retest that I've seen before include "Examine afresh" , "Make a further assessment" , "Set another examination" , "Once again try" , "another audition!" .)

I've seen this clue in the Sydney Morning Herald.
