I do see the debugging value that you're talking about, but the danger in extensive testing of private methods is that it makes the test cases fragile.

The important thing when you are refactoring is that all of the public methods continue to adhere to the interface; if you have to update your test suite every time you make a change you might be reluctant to make internal improvements.
