Teardown
Daunting legacy code challenges can scare away the best developers. In this chapter, you’ve learned that, yet again, an incremental approach works well for tackling the problem. With a modicum of investment around safe code restructuring, you can keep moving forward. You don’t need to test everything, just the stuff you need to change!
You’ve also learned how to make broad, sweeping changes across your system with minimal stress by using the Mikado Method.
In the next chapter, you’ll learn how to use TDD to help tackle one of the bigger challenges in software development: how to craft a robust, multithreaded application.
