PHPUnit

PHPUnit is a unit testing framework for the PHP programming language, designed to facilitate automated testing of PHP code. It provides a comprehensive set of assertions, test runners, and mocking capabilities to help developers write and execute tests efficiently. As part of the xUnit family, it follows the same patterns as other unit testing frameworks like JUnit for Java.

Also known as: PHP Unit, PHPUnit Framework, PHPUnit Testing, PHPUnit Tool, PHPUnit Library

Why learn PHPUnit?

Developers should learn PHPUnit to ensure code quality, catch bugs early, and support refactoring in PHP applications, particularly for large-scale or enterprise projects. It is essential for implementing test-driven development (TDD) or behavior-driven development (BDD) workflows in PHP, and is widely used in frameworks like Laravel and Symfony for automated testing.
