automated mocks generation

[lbartnik]

Did you consider adding support for automated mocks? An example from the Java world could be this: https://code.google.com/p/mockito/

It's not at all obvious to me how mocking should work for non-message-passing OO, plus I've never really found a need for them. But if you put together a proposal, I'd be happy to give feedback.

I had to change my priorities. Once I'm back to this particular problem, I'll post a follow-up.

@wch has put together an outline in a comment to r-lib/devtools#388. It's about mocking individual functions in the package to be tested, still it would be great to see this integrated in testthat.

I don't have any plans to work on this, but if you want to supply a pull request, I'd happily review.
