Where private methods (not part of the public API) provide a unit of
functionality, we unit test them.
We like to specify code behaviour in our test names (similar to some of
the BDD stuff I think, but I haven't had a chance to read much on this
yet). Specifying behaviour for the code only through the public API can
lead to some very complex tests / specifications.
It is often easier to specify public API behaviour in terms of calling
down to private methods - and then mock out these private methods in the
test of the public API. The private methods can then be tested separately.
All the best,
