If you really have private methods; and if you can provably cover all
code paths with tests of the public API, then I would say you are
okay to only do that. If you can't cover everything using just calls
to the public API, then your choices are to a) add tests to the
private methods, or b) remove the logically unreachable code.
Protected methods can be called by your subclasses, so you should
test them directly.
If, like most perl code, you don't really have private methods, you
have to test everything, because someone, someday is going to use it.
Speaking of coverage... it seemed like a few people at the last
meeting were unfamiliar with using Devel::Cover together with unit
tests. If there's interest, I could probably put together a talk
about it. (But not for March.)
