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.

Refactoring Game of Life Kata to Patterns

In the lesson, Object Calisthenics, we introduced Game of Life as an exercise to practice the rules. If you have done this exercise, you should have it saved somewhere and that will be the starting point for this exercise. If you have not done it, we suggest you give it a go. Once you have done your implementation, you will be ready to carry on.

This exercise consists of refactoring your current Game of Life and solving it with different design patterns. Interesting implementations in this scenario could be:

  • Command patterns
  • State patterns
  • Strategy patterns

Chose one pattern and refactor to it using the refactoring suggestions of previous lessons. Once done, choose another pattern and refactor to it. Rinse and repeat.


This exercise is meant to help internalize the implementation of a few patterns and prove that there are many ways to use patterns to solve a problem. Realistically, you should derive...
