AI AGENTS
by PestPHP
Pest is an elegant PHP testing framework with Composer installation, a documented CLI test runner, and official agent-oriented docs for AI coding-agent test verification.
Pest is presented on its official website as an elegant PHP testing framework, and its GitHub repository describes it as a testing framework for PHP developers and AI agents. The official installation documentation shows Composer-based setup with the pestphp/pest package and the vendor/bin/pest CLI. Pest’s CLI reference documents test-running workflows such as initialization, CI mode, test-directory selection, filtering, and coverage. Official Agent documentation also describes a Pest Agent plugin that gives AI coding agents a single command to verify changes inside the full test suite, with source code in the pestphp/pest-plugin-agent repository identified as the Pest AI Plugin.
Use Pest when you need a PHP testing framework with official Composer installation and a vendor/bin/pest CLI workflow. Use Pest when you want documented command-line options for initialization CI runs test-directory selection filtering and coverage workflows. Use the Pest Agent/Pest AI Plugin workflow when an AI coding agent needs a documented way to verify changes against the full test suite.
