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.

Using shell scripts to run tests

We can use shell scripts to run our tests for us, and by doing so, we can add extra configurations to each script. There are different configurations and commands to run when running PHPUnit tests, and there are different goals or intentions in mind when running unit tests. In this chapter so far, we ran tests to trigger Xdebug and go through codes, and we also used PHPUnit to get a report for our test coverage. To simplify the execution of these tests a bit better, we can build some shell scripts to help us encapsulate the commands and configurations to run the tests.

If you go back to your terminal and try to use Xdebug with a breakpoint, you’ll probably be disappointed. In PHPStorm, put a breakpoint like so in one of the tests:

After putting a breakpoint inside the CalculationTest.php class on line 16, run the following command:
