I'm writing master thesis about evaluation of source code metrics with a use of refactoring patterns. I would like to examine metrics before and after set of refactorings and check how they change.
But now I'm looking for something bigger than examples from "Refactoring" by M. Fowler, "Refactoring to patterns" or "Clean code".
Does anybody know about project with this two snapshots (before/after refactoring) available?
