We will discuss the importance of tests when refactoring in Chapter 3. Extreme Programming also mandates continuous refactoring. The new feature is then implemented and passes at least a single new test and all current unit tests.

The code is then refactored to support implementing another feature and pass all the existing tests.

XP mandates a Test-Driven-Development ( TDD) processп»ї, where only enough code is written to implement a single feature and to pass at least a single test. Kent Beck introduced XP in the book Extreme Programming Explained circa 1999.

Refactoring has been an integral part of software development in the Extreme Programming ( XP) methodology since Kent Beck introduced it in 1999. Although refactoring is a fairly simple concept, many programmers don't associate changing code without changing external behavior as being refactoring. Few developers would argue that refactoring isn't something they do on a day-to-day basis. The term refactoring has been around since at least the early 1990's. Factoring was a common term used in the Forth programming language (and mathematics) to mean decomposition into constituent parts. The term refactoring was coined by William Opdyke in what seems to be an evolution of factoring. Changes to internal structure and interfaces that don't affect the system's external behavior are considered refactoring. Refactoring is changing the design of a software system without changing its external behavior. As an end result, you will have an adaptable system with improved code readability, maintainability, and navigability.ДЄ pattern is a a problem which occurs over and over again in our environment, and then describes the core of the solution to that problem, in such a way that you can use this solution a million times over, without ever doing it the same way twice. You will be able to support your evolving code base by refactoring architectural behavior.

You will also be able to apply standard established principles and patterns as part of the refactoring effort with the help of this book.

The book also covers how to ensure quality in the light of seemingly drastic changes to a software system. You will learn how to change the design of your software system and how to prioritize refactorings-including how to use various Visual Studio features to focus and prioritize design changes. It begins with simple refactoring and works its way through complex refactoring. This book introduces you to improving a software system's design through refactoring. These features make it simple to handle code and prove helpful for refactoring quickly.

To do this, we will use enterprise editions of Visual Studio, which incorporate features like Application Performance Explorer and Visual Studio Analyzer. This book will discuss large-scale code management, which typically calls for refactoring. Visual Studio includes some basic refactorings that can be used independently or in conjunction to make complex refactorings easier and more approachable. This book will show you how to make your code base more maintainable by detailing various refactorings. As you consider the benefits of refactoring, you will need this complete guide to steer you through the process of refactoring your code for optimum results. Refactoring recognizes this reality and systematizes the distinct process of modifying design and structure without affecting the external behavior of the system. Changes to design are an everyday task for many people involved in a software project.
