I usually test all of the public API of something and only it. Exported functions, classes, constants and whatever should be tested and properly documented. If writing tests for the public surface is not enough, most likely the underlying code is poorly written, probably lacking proper abstractions to expose the adequate state associated with a determined behaviour (e.g.: a class that does too much).
Life can be very paradoxal at times.
