Deep mock method

[derrley]

It should be easier to mock a method that's "deep" in the class's structure. While this is generally bad practice, sometimes, when mocking legacy interfaces, it is necessary.

some_mock.something.something_else.something_even_else.expect()

This could be a mode, where rather than failing, a mock method could automagically construct the thing it's trying to grab as a sub mock method
