Don’t start looking for issues right from the word GO.
Only idiots do that. Imagine you are handed a machine. You don’t know what its made of, you have some idea of what it should do and you are asked to test it. What should be your first thought? Mine is ‘How do I use it?’ If you don’t know how to you use it, how its supposed to work and who exactly is the user, do you think testing it would be fruitful. So the next time someone hands you a piece of code, start from how to use it, get comfortable as if you are a user of it on a daily basis and then maybe you can start thinking of ways to find issues with it.
