'analysis' is the definition.
(analysis can mean testing something)

'hard to leave classic heist film' is the wordplay.
'hard' becomes 'set' (similar in meaning).
'to leave' shows that the letters should be reversed in order (I've seen 'left' mean this).
'classic heist film' becomes 'ting' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'set' reversed gives 'tes'.
'tes'+'ting'='TESTING'

Can you help me to learn more?
