WRT framework, no there is nothing related to this in the book. However, I would highly recommend you verify that such a framework does not already exist!
WRT TDD, I don't have any idea. Some hints. First, if you're not doing TDD, it's unlikely you'll get close to 100% test coverage. If you're not doing TDD you'll also spend a considerable amount of time refactoring your code when the code's first users try to use it. You can try asking the question on the TDD mailing list (on yahoogroups).
