3.7 Test Services

If your plugin needs extra services or overrides used only during tests, add them in tests/TestApplication/config/services_test.php.

Example:

<?php

declare(strict_types=1);

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

return function (ContainerConfigurator $container): void {
    $env = $_ENV['APP_ENV'] ?? 'dev';

    if (str_starts_with($env, 'test')) {
        // Add or override services here, e.g. fake clients, stubs, test configs
    }
};

Important: You must also import this file in config.yaml .
