I love refactoring code. To refactor code safely you need automated tests. Some code, especially code not written using Test Driven Development(TDD), make it difficult to write tests for the part of the code you are looking to change. Usually what you face are a class that has many dependencies, so in your test setup, you have to create all these dependencies to inject into the constructor even though many or perhaps all of these dependencies don't even have anything to do with the part of the code you are looking to change.
