What are the psychometric tests used for diagnosis of depressive disorder?
There isn’t a single depression test or screening that determines if someone is clinically depressed. Unlike lab tests that diagnose some illnesses, a depression test is just one tool that a professional might use when screening for and diagnosing a mental health condition like depression.

@anurup Depression tests are often in the form of a questionnaire. A physician or mental health professional may ask the questions orally or an individual may be asked to read and answer the questions on paper or on a digital device. The answers alone aren't enough to determine if someone has depression because a test won't account for other possible reasons for an individual's answers. For example, someone experiencing acute pain may report difficulty sleeping and poor appetite—but those symptoms may be caused by pain rather than depression. A clinician would need to take their physical health condition into account after reviewing the test results.
Similarly, a treatment provider would also need to take someone's environment into account. Someone may report difficulty sleeping not because he's depressed, but because he has a loud neighbor who keeps him up at night.
