Like I said, you wouldn't want a huge refactor of the code there, because it's already tested and probably very testable the way it is. Otherwise it wouldn't have this good test suite. Modularization is the issue, not size. If you have a big project and it's nicely modularized you probably already have good tests for it, but don't need to refactor. If it's big and needs a huge refactor it's probably hard to test and doesn't have appropriate tests.
