About the 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 how 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 lessons 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.
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 (São 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.
Learning Objectives
- Apply the red, green, and refactor cycle of TDD to solve procedural problems
- Implement the various techniques used in the pair programming approach
- Use code smells as feedback
- Test your production code using mocks and stubs
- Refactor legacy code to bring it in line with modern agile standards
- Apply the object calisthenics ruleset to enhance your software design
Approach
The content in this book is presented as a journey. Each concept is introduced gradually. New concepts are added on top of the previous materials. Several exercises are available for you to spend some time practicing the new material.
Audience
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.
