A Quick Recap

In this chapter, we've learned how the following tenets of extreme programming make the debugging process easier and more effective:

• Software is specified, integrated, and released incrementally.

• Design is kept as simple as possible.

• Programming is done in pairs.

• An on-site customer is always available.

• Code is owned by all developers.

• Tests exist for "anything that could possibly break."

In Chapter 4, we'll discuss how to design code with testability in mind.
