Testers need to be nice

This is most probably one the most important things in testing. Basically you are the person who has to basically tell the developer that their baby is ugly. It is important to get along with the developers well especially when you need to work at the desk next to them. It also helps if the developer when you say there is a bug doesn't take as if you are calling their baby as ugly.

What can help is if you you get along with the developers outside of raising bugs as if they know you they are generally much better about he raising of bugs.
