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.

It's the Design...

After spending a few lessons on test-driven development, we'll now turn our attention to simple design. Why do we need to consider design?

  • TDD is not enough: TDD will have a positive side effect on design, but simply doing TDD will not take care of design by itself.
  • DRY (Do not Repeat Yourself) is not enough: So far, our refactoring efforts have been focused on removing duplication. This is crucial to write maintainable code, but it is not enough.
  • TDD will punish you if you don't understand design: When we find ourselves writing very complex test code, we should consider changing the design of the implementation.

We'll also move from using TDD to solve simple algorithmical problems to problems that require more design decisions.
