I believe he's talking about unit testing. What platform are you developing on, sixstringartist?

Also, at a guess, I'd say that sixstringartist knows a thing or two about finding primes already. As he correctly remarks, you only need to test up to the square root of the number to check if it is prime or not, which suggests that he's already familiar with how to efficiently test for primes. So I'm not sure you need to give him advice there
