Very basic question: if a method becomes deprecated over time, are its unit
tests retained in the Test classes on the off chance that they may become
relevant again? Do they get commented out or are they left to run?

Am I safe in assuming that once the method is actually removed from the
class, the test cases are deleted as well?

As Java gets more mature, it's not unusual to see deprecated methods from
time to time. Have any methods in the Java API actually been deleted or are
they all just kept around in a deprecated state? What about Java classes
outside of the Java API? Just curious....

Since a method's being deprecated doesn't mean that no one calls it , it
still need to be tested.

Continue to test.

Yes. Because the test case would neither run nor compile.

I am not aware of any.

Some open source projects has made incompatible upgrades.

Left to run.

I can't think of any that have been removed.

To take one example, HtmlUnit has made numerous backward-incompatible API
changes, removing methods, renaming them, moving them, etc. Their process
(IIRC) is to deprecate in one release, then remove in the next.
