Above all, you do not let your tests drive your design, you let your design drive your tests! The design is going to point you in the right direction of what layer in the MVC cake should get the most test frosting. When you stop driving your design first, and primarily, through your tests, your eyes will open to much more interesting perspectives on the code. The answer to how can I make it better, is how can I make it clearer, not how can I test it faster or more isolated. The design integrity of your system is far more important than being able to test it any particular layer. Stop obsessing about unit tests, embrace backfilling of tests when you're happy with the design, and strive for overall system clarity as your principle pursuit.
