The document discusses continuous testing in software development, specifically focusing on its implementation with PHP and various guard plugins. It provides a detailed guide on setting up and configuring automatic tests using tools like Guard, PHPUnit, PHPCS, and Behat. The document also includes code snippets and configurations for managing notifications and executing tests in real-time during development.
