• Description should be language-agnostic

• Does not mention min should always be <= max

how is the construction 21 + 22 + 23 + 51 + 52 + 53 is it equal to 30 ? if the result is 42

OP solved it, closing

Test.assertEquals(sumTimesTables([],1,10), 0, "Empty array");

Fixed by OP

Approved

python new test framework is required. updated in this fork

Python: Random tests are vulnerable to input modification

Why would it be slower? Not that performance matters when you are doing code golf.

It will shave a few bytes but on the other hand the time of execution will be longer

You can omit the ; and replace && with & to shave a few bytes

The result variable in line 2 is a "suprise global". Just so you know

I think this is just missing a few newlines to be perfectly readable production-quality code.

Very nice with the (sum) usage
