I don¡¯t know how many tests you really need for a python one-liner like that.
`return any((sum(pair)==6) for pair in permutations(list, 2))`
Check empty list returns false?
Check for no matches
Check for one match
Check for invalid input handling
There really aren¡¯t many invariants to lock down for refactoring purposes.
I guess you could do more than that, but at some point you¡¯re testing the compiler and the library (someone else¡¯s code) and not your algorithm.
