PHPUnit Framework

PHPUnit is a testing framework designed to help developers ensure their PHP code works correctly. It automates the process of checking individual pieces of code, called tests, to confirm they produce the expected results. By running these tests regularly, developers can quickly identify and fix bugs, improve code quality, and maintain confidence as their software evolves. Think of it as a specialized tool that verifies each part of a PHP application functions properly, saving time and reducing errors in the development process.
