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.

Applying Behavior-Driven Development

In the previous chapter, we learned how to create and use unit tests to our advantage. We used unit tests and integration tests to help ensure the stability of our solution code. That was probably like learning how to do a basic punch on a punching bag. If you go to a boxing class, they’ll probably teach you how to use your basic punch more effectively and teach you how to use that basic punch to do combinations of punches, as well as how to defend against them. That’s akin to what behavior-driven development (BDD) and test-driven development (TDD) are. We first need to start with the basics: unit and integration testing. Now that we have those basics, we can start applying processes or techniques so that we can use them more effectively.

A lot of developers know how to write unit tests and integration tests—after all, these tests are just programs that we developers write. From my personal experience, what I’ve noticed...
