If unit tests are hindering your refactoring then you aren't writing SOLID code. The only time I find myself, e.g. splitting a class in two, and then having to deal with its shitty tests, are when I'm dealing with legacy classes that did five things at once. Oh, and their tests were just "did it crash?" tests, i.e. call a method but only check the happy path. If you have reached the point where you feel tests hinder refactoring then you have two paths: a/ learn to write smaller, SOLID classes, or b/ meh unit tests are stoopid.
