Overview of this book

The world is moving away from bulky, unreliable, and high-maintenance PHP applications, to small, easy-to-maintain and highly available microservices and the pressing need is for PHP developers to understand the criticalities in building effective microservices that scale at large. This book will be a reliable resource, and one that will help you to develop your skills and teach you techniques for building reliable microservices in PHP. The book begins with an introduction to the world of microservices, and quickly shows you how to set up a development environment and build a basic platform using Docker and Vagrant. You will then get into the different design aspects to be considered while building microservices in your favorite framework and you will explore topics such as testing, securing, and deploying microservices. You will also understand how to migrate a monolithic application to the microservice architecture while keeping scalability and best practices in mind. Furthermore you will get into a few important DevOps techniques that will help you progress on to more complex domains such as native cloud development, as well as some interesting design patterns. By the end of this book you will be able to develop applications based on microservices in an organized and efficient way. You will also gain the knowledge to transform any monolithic applications into microservices.

Preface

Test-driven development


Test-driven development (TDD) is part of agile philosophy, and it appears to solve the common developer's problem that shows when an application is evolving and growing and the code is getting sick. The developers fix the problems to make it run but every single line that we add can be a new bug and it can even break other functions.

TDD is a learning technique that helps the developer to learn about the domain problem of the application they will build, doing it in an iterative, incremental, and constructivist way:

  • Iterative because the technique always repeats the same process to get a value

  • Incremental because for each iteration, we have more unit tests to be used

  • Constructivist because it is possible to test everything we are developing during the process straightaway so that we can get immediate feedback

Also, when we finish developing each unit test or iteration, we can forget it because it will be kept throughout the entire development process, helping us to...
