Synopsis
Delve deep into the various technical practices, principles, and values of Agile.
Key Features
- Discover the essence of Agile software development and the key principles of software design
- Explore the fundamental practices of Agile working, including test-driven development (TDD), refactoring, pair programming, and continuous integration
- Learn and apply the four elements of simple design
Book Description
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.
What you will learn
- Learn the red, green, refactor cycle of classic TDD and practice the best habits such as the rule of 3, triangulation, object calisthenics, and more
- Refactor using parallel change and improve legacy code with characterization tests, approval tests, and Golden Master
- Use code smells as feedback to improve your design
- Learn the double cycle of ATDD and the outside-in mindset using mocks and stubs correctly in your tests
- Understand how Coupling, Cohesion, Connascence, SOLID principles, and code smells are all related
- Improve the understanding of your business domain using BDD and other principles for "doing the right thing, not only the thing right"
Who this book is for
This book is designed for software developers looking to improve their technical practices. Software coaches may also find it helpful as a teaching reference manual. This is not a beginner's book on how to program. You must be comfortable with at least one programming language and must be able to write unit tests using any unit testing framework.

About the Authors
Pedro M. Santos has over 25 years of experience in the software industry. He has worked in the finance, aviation, consultancy, media, and retail industries and has built a wide range of software, ranging from embedded systems to cloud-based distributed applications. He has lived in Portugal (Lisbon), Brazil (Sao Paulo), Spain (Madrid, Barcelona), Netherlands (Hilversum), and Belgium (Gent), and, currently, he is based in the UK (London), where he focuses on educating and inspiring other developers. He has spent hundreds of hours in pairing sessions as well as coaching and mentoring developers at all levels of proficiency. His tutoring experience covers almost every aspect of software development: programming basics, object-oriented and functional design principles, refactoring legacy applications, pragmatic testing practices, architectural decisions, and career development choices.

Marco Consolaro is a software craftsman, systems thinker, agile technical coach, entrepreneur, philosopher, and restless traveler – all blended with Venetian humor. Marco learned to code in Basic on a Commodore when he was 9 years old. He graduated from Venice University in 2001 with a degree in Computer Science. Since then, Marco has worked in Italy and the UK and is always looking to learn something new. When his journey led him to the agile principles, he quickly realized the effectiveness of such an approach for both technical and organizational areas. He now strongly believes that an iterative approach based on trust, transparency, self-organization, and quick feedback loops is the key to success for any team in any discipline. His dream is to see these principles based on systems thinking understood and implemented at every level in businesses and public administrations. Follow Marco on Twitter at @consolondon.
Alessandro Di Gioia has helped a variety of companies (from small startups to large enterprises for the past 18 years) embrace agile technical practices. He has worked in Italy and Norway. For the past few years, he has resided in London. His professional life changed when he came across agile methodologies, especially Extreme Programming. He likes concise, expressive, and readable code as well as making existing solutions better when needed. He is always trying to learn better ways of designing asynchronous distributed architectures and crafting software, in either an object-oriented or functional style. Although Alessandro considers himself a forever learner, he is also a coach and a mentor because he loves to share his experiences with others. Follow Alessandro on Twitter at @Parajao.
