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.

Writing PHP code based on Gherkin

We will need PHP programs to represent the features and scenarios we created using Gherkin. The Behat framework will follow the features and scenarios we created in the previous section, but it will also look for PHP code that represents each feature and scenario. Within this PHP code, we can add any custom logic we want to interpret the features and scenarios into programs. Create the following files that the Behat framework needs to run our features and scenarios:

  1. First, we need to create a new context class. A context class is what Behat uses to represent Gherkin features into PHP programs.Create the following file with the content shown:


use Behat\Behat\Tester\Exception\PendingException;
class HomeContext implements \Behat\Behat\Context\Context
  1. Then, after creating the HomeContext.php class, we also need to tell Behat that we have a...
