That sounds great.

There are a few reasons for this:

We should make sure unit tests we write for the Platform API doesn't reduce
the hackability / refactor-ability of the code.  It's very easy to write a
lot of unit tests around an internal API that prevent large architectual
changes.  Just look at webkitpy!  It's impossible to hack on that codebase
due to thousands of unit tests that depend on non-public API.
