If you mean 'how do I test if a class, or any of its ancestors, supports a method?', then can is your friend i.e. in your case, the test would become $TEST->can(q/test_sub/).

Otherwise, if the question revolves around a sub/method being defined in a specific module, then you were close, but you forgot to consider precedence - if you'd have written defined &{$TEST->test_sub} or defined &{qq/${TEST}::test_sub/}...

P.S. Thanx for the tip almut - originally forgot the braces in the string

A user level that continues to overstate my experience :-))
