In your report:
Identify the specific test you took, and
provide an active link to that test.
Compare the test items in that test with the kinds of things that should be included in tests of personality that would correspond to the aspects of personality described in your textbook or in personality web sites you visited.
Try to find, and discuss, any information that indicates anything about the validity and reliability (review Chapter 10) of the test you took. If you cannot find any such information, use your best judgment to determine how that test might fare.
Use "proper" terminology throughout.
