I’m currently on a co-op term working on a project nearing completion with one other co-op student. Since this project has been passed down from co-op to co-op, poor practices have been taken along the way and testing has been left until the end. I’ve decided I’d like to write unit-tests to learn something new while testing.
However, I’m working on a 3-tier, tightly coupled app that seems impossible to unit test in its current form. I don’t want to throw off the other co-op student with no knowledge of any of these concepts by refactoring the code beyond recognition overnight. So what steps should I take to slowly pull the code towards unit-testability? Should I first implement a factory pattern and let the other student familiarize themselves with that before moving forward?
My apologies if my knowledge is flawed and there should be no issue whatsoever. I’m new to this 🙂

Hard to know if implementing a factory pattern will do any good, depends on what the code is doing 🙂
