Test-Driven Development with PHP 8

By: Rainier Sarabia

Overview of this book

PHP web developers end up building complex enterprise projects without prior experience in test-driven and behavior-driven development which results in software that’s complex and difficult to maintain. This step-by-step guide helps you manage the complexities of large-scale web applications. It takes you through the processes of working on a project, starting from understanding business requirements and translating them into actual maintainable software, to automated deployments. You’ll learn how to break down business requirements into workable and actionable lists using Jira. Using those organized lists of business requirements, you’ll understand how to implement behavior-driven development (BDD) and test-driven development (TDD) to start writing maintainable PHP code. You’ll explore how to use the automated tests to help you stop introducing regressions to an application each time you release code by using continuous integration. By the end of this book, you’ll have learned how to start a PHP project, break down the requirements, build test scenarios and automated tests, and write more testable and maintainable PHP code. By learning these processes, you’ll be able to develop more maintainable, and reliable enterprise PHP applications.

Understanding OOP in PHP

Can I use PHP with TDD? Absolutely – and PHP, thanks to its OOP capabilities, works well with TDD. We have previously explained that TDD is a process; it’s not a piece of software that you can install. You can install or download tools to implement TDD, and there are a lot of different tools available for other programming languages as well.

Since PHP 5 was released in the early 2000s, classes and objects were supported, allowing OOP to be used for PHP. It would be an advantage if the reader has a good understanding of OOP and has worked on PHP OOP projects, but if not, I’ll do my best to introduce OOP to you, as it is an effective and efficient way to write software. We will also be using OOP in our example project, so we need to make sure that the reader understands OOP.

What is OOP, anyway?

OOP is a programming style based on the concept of classes and objects. One of its goals is to let software developers write reusable and...
