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.

What Does Each Element Mean?

Passes Its Tests

TDD is a very effective way to limit the amount of code we write, as we are only writing enough code to make the failing test pass. Tests help prove that the system is implementing the expected behaviors. There is no point in having a beautifully designed system if it does not implement the expected behaviors; this is why Passes its tests is the first rule.

Tests also allow us to refactor the design with caution, allowing us to tackle design issues safely and effectively. Finally, tests serve as documentation to improve the clarity of the system.

Minimizes Duplication

Duplication is the first code smell we examined in this book. It is an important indicator we can use to detect problems in our code. Removing duplication often leads us to create new abstractions that more clearly express the intent of the code, thus increasing clarity.

Code duplication leads to many problems in design. This is the reason why this is the second...
