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.

Setting up our PHP development container

We will need a development environment for our PHP application. We will be separating our development environment structure into two main parts: the Docker container (server) and the PHP application.

The docker directory will contain the following:

  • Dockerfile
  • docker-compose.yml
  • Server configurations

The codebase directory will serve as the following:

  • The root directory for our PHP application
  • Vendor directory for composer packages

Now, let us set up our PHP development container:

  1. Create the following directory structure in your machine:

  1. Run the following commands:
    $ mkdir -p ~/phptdd/docker
    $ mkdir -p ~/phptdd/codebase
  2. Install Docker Desktop. Before we create the required Docker files, we will need to download and install Docker Desktop.

For macOS users, Docker can be downloaded from
