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.

Object Calisthenics Preventing Code Smells

Object calisthenics is a set of rules that help us avoid some code smells. If we decide to break the rules, we'll have consequences that materialize as code smells. In design, following rules is not always the best path; sometimes we need to bend or break rules. This is fine as long as we are conscious about it; namely, the consequences and the benefits. Software design should be a series of decisions. Our worst enemy is accidental complexity due to unconscious design decisions.
