Agile Technical Practices Distilled

By: Pedro M. Santos, Marco Consolaro, Alessandro Di Gioia

Overview of this book

The number of popular technical practices has grown exponentially in the last few years. Learning the common fundamental software development practices can help you become a better programmer. This book uses the term Agile as a wide umbrella and covers Agile principles and practices, as well as most methodologies associated with it. You’ll begin by discovering how driver-navigator, chess clock, and other techniques used in the pair programming approach introduce discipline while writing code. You’ll then learn to safely change the design of your code using refactoring. While learning these techniques, you’ll also explore various best practices to write efficient tests. The concluding chapters of the book delve deep into the SOLID principles - the five design principles that you can use to make your software more understandable, flexible and maintainable. By the end of the book, you will have discovered new ideas for improving your software design skills, the relationship within your team, and the way your business works.

Refactor Code Smells

Martin Fowler, in his excellent and groundbreaking book, Refactoring: Improving the Design of Existing Code, creates a categorization and terminology for many refactors. We will not dive into this too much since it's covered in his book. Terminology is often disregarded, but it plays an important role in communicating effectively. In the following table, we list the most common refactors we can use to remove particular code smells. The refactors in this table are also taken from Fowler's book:

Figure 7.2: Refactor code smells

BLO – Bloater, CHP – Change preventer, COU – Coupler, DIS – Dispensable, OOA – Object Orientation Abuser

For those interested in a deeper dive into the world of refactoring, see the web links and books in the Resources section of this lesson.
