PHPUnit Extension for Symfony AI Mate

Token-efficient PHPUnit tools for AI assistants. This package runs tests and returns encoded structured responses designed for debugging and iteration.

Features

• run the full suite, a file, a class, or a single method through one tool
• list discoverable tests
• encoded output with three consistent detail modes
• custom command support for containerized setups

Installation

composer require --dev matesofmate/phpunit-extension
vendor/bin/mate init

In current AI Mate setups, extension discovery is handled automatically after Composer install and update. Run vendor/bin/mate discover when you want to refresh discovery artifacts such as mate/AGENT_INSTRUCTIONS.md.

Useful Mate commands:

vendor/bin/mate debug:extensions
vendor/bin/mate debug:capabilities
vendor/bin/mate mcp:tools:list --extension=matesofmate/phpunit-extension

Use the generated wrapper for Codex:

./bin/codex

Custom Command Configuration

If PHPUnit must run through Docker or another wrapper command, configure matesofmate_phpunit.custom_command.

use Symfony\Component\DependencyInjection\Loader\Configurator\ContainerConfigurator;

return static function (ContainerConfigurator $container): void {
    $container->parameters()->set('matesofmate_phpunit.custom_command', [
        'docker', 'compose', 'exec', 'php-test', 'vendor/bin/phpunit',
    ]);
};

Requirements

• PHP 8.2+
• Symfony AI Mate 0.8+ required
• PHPUnit available locally, or a custom command configured

Available Tools

• phpunit-run
• phpunit-list-tests

All tools return encoded strings through Mate's core ResponseEncoder. Install the suggested helgesverre/toon package if you want TOON responses; otherwise the same payload falls back to JSON.

Output Modes

• default
• summary
• detailed
