Validity is the question of whether the usability test measured what was thought it would measure, i.e., provide answers to. Typical validity problems involve: using the wrong users, giving them the wrong tasks.
(Example from expert evaluation: "The reviewer is an experienced usability professional that has evaluated systems for many years. We therefore feel that the method used as well as the tasks used give an appropriate view of how ordinary users would behave in the system.")
