This study looks at this last question by taking a systematic approach to finding and evaluating evidence of reliability and validity for 15 language tests. Importantly, the authors looked at evidence from peer-reviewed papers in addition to the stuff in the front of the test manuals.

Test validity is the extent to which a test (such as a chemical, physical, or scholastic test) accurately measures what it is supposed to measure.
