According my experience, I think, the most important consideration in determining whether a test is good or not is the use for which it is intended.That is to say, the most important quality of a test is its usefulness. It is believed that test usefulness provides a kind of metric by which we can evaluate not only the tests that we develop and use , but also all aspects of test development and use. Genenally speaking, usefullness quality includes six components :reliability, construct validity, authenticity, interactness, impact and practicality. However, there is problem that should be pointed out that rather than emphasizing the tension among the different qualities, test developers need to recognize their complementarity. In the end, I hope my response may offer you some help.
