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.

Passing the Behat registration feature

Now that we have a couple of failing Behat tests for the login feature, let’s try to do the minimum amount of work to complete the feature, and pass the tests. Luckily, Symfony makes it easy to implement security. We can use the symfony/security-bundle Composer package to add authentication and authorization to our application, without having to build everything from scratch.

To pass the failing Behat registration feature, as Behat simulates a user using a web browser, we will have to create all the programs needed for a real user to be able to register an account in our application from the web browser, which then hits the controllers, the services, and then down to the database persistence process. Let’s start with the controllers.
