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.

Outside-in, from a systemic point of view, means focusing first on one of the most important aspects, the public interface, which for a system represents the communication with the external world. Remember that we see software as a system of systems? This is the reason for the quote of Alan Kay at the beginning of this lesson.

Furthermore, using this way of development fits incredibly well with the most popular IDE frameworks. Sketching the outside-in methods allows us to use quick shortcuts for almost every operation involving interface creation, class creation and method creation. It makes development mainly a matter of naming things and using the autocomplete functionality of the...
