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 introduced Docker and used it to create and run containers. Containers are instances of packaged applications. Although we have seen that containers are packages and isolated, they can also communicate with each other. For instance, our example PHP program is running inside the server-web container and then connects to the server-mysql container that runs our MySQL server.

We’ve seen how simple it is to launch containers. We have two PHP containers running (server-web and app-phpmyadmin) and one database container (server-mysql), and we can run more containers if we need to. We will be using the base containers we have created to build our PHP project; we will continue modifying our containers and will install more libraries and tools as we go along.

In the next chapter, we will start building our base PHP application. We will try to go through the features and reasons why we decided to use PHP in the first place. We will be installing the...
