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 New Relic APM for PHP

There are a lot of different APM tools available out there, but in this book, we will just focus on using New Relic.

New Relic offers a lot of performance monitoring tools, but in this book, we will focus on monitoring our PHP application, and the infrastructure it runs on top of.

In this section, we will install and configure the New Relic PHP agent in our EC2 instance so that we can start collecting PHP and server data.

Creating a New Relic account and license key

The first thing you will need before installing the New Relic agent into the EC2 instance is a free New Relic account. You can sign up at to create a free account. You will need your license key later in the setup process.

The license key can be found on the New Relic API keys page under the Administration dashboard:
