The purpose of this assignment is to explore two Extreme Programming (XP) practices: test-driven development and refactoring. The practice of test-driven development calls for software developers to create tests before code is actually produced. The example in Chapter 21 is based on unit testing, but test-driven development can be applied to other tests, such as feature tests, usability tests, load tests, etc.

Refactoring is a programming practice aimed at refining code without changing its behavior (it is not debugging). Over time about 100 named refactoring patterns have been identified.

In this memo to your supervisor, you will summarize the key points behind test-drive development and refactoring, and you will identify an example of how refactoring can be applied.

Test-driven development and refactoring are practices that you can apply now in your other classes, and later in an internship or in your career.
