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.

In this chapter, we defined what OOP is and why we’d want to take advantage of it. Then, we clearly defined what classes and objects are in PHP. We then went through some examples for each of the Four Pillars of OOP. We learned what abstraction, encapsulation, inheritance, and polymorphism are and how they work in PHP. We’ve also briefly gone through the PSRs because we don’t just want to go ahead and invent standards and start writing codes – we want to produce clean PHP code that is easy to understand and maintain, especially in an enterprise environment where you can expect to work with a lot of other developers, and where your codes will have to be very readable and maintainable for years to come.

This chapter should have prepared you to start writing actual object-oriented PHP code – and in our TDD example project, we will take advantage of the OOP capabilities of PHP.

In the next chapter, we will talk about unit testing. We will...
